Cisco Unified CommunicationsManager Express Data Streams

Signaling and Session Control flows between Cisco UnifiedCommunications Manager Express and the IP phone.Cisco Unified Communications Manager Express instructs the IPphones to listen on a port

The audio stream flows directly between the IP phones.

Unified CME'

IP Phone A -*- »*• IP Phone B

" Unified CME - Cisco Unified Communications Manager Express I

Cisco Unified Communications Manager Express uses Session Initiation Protocol (SIP) orSkinny Client Control Protocol (SCCP) to communicate with the IPphones for call setup andsignaling.

When thecall is set up. media exchange occurs directly between the IPphones using the Real-lime Transport Protocol (RTP) to carry the voice data. Inthe figure, userA on phone A wantsto make a call to phone B. UserA dials the numberof user B.The dialeddigits are sent toCisco Unified Communications Manager Express, which is the call-processing engine. CiscoUnified Communicalions Manager Express finds the IP address and port number of the calledIP phone and determines how to route the call.

Using the SCCPor SIP protocol. Cisco Unified Communications Manager Express signals thecalling partv over IP to initiate a dialing tone, and user A hears the dial lone. Cisco UnifiedCommunications Manager Express also signals the call to the destination IP phone, which startsringing. When user B accepts the call, the RTP media path is opened between the two IPphones.

The IP phones require no further communication with Cisco Unified Communications ManagerExpress until either user A or user B invokes a feature, for example. Call Transfer or callconferencing, or ends the call.

The main capabilities of Cisco Unity Express are:* Provides voice mail features

• Auto-attendant capabilities

• IVR" support

• Support for fax messages

* Survival remote site voice mail

• MR - Interactive Voice Response |

Cisco Unity Express is available on selected voice-enabled Cisco Integrated Service Routers,but uses its own architecture and processing unit, which is located in a module slot on a CiscoIntegrated Service Router or a Cisco Integrated Service Router Generation 2 router, to providethe following features:

• Voice mail: Provides messaging and greeting services for increased customer service andefficient employee communications. The maximum number of mailboxes depends on thehardware module and license agreement that is purchased for Cisco Unity Express.

• Auto-attendant: An auto-attendant might replace the operator and allows the caller to self-direct their call. Some common functions that an auto-attendant provides arc the following:

— The caller can spell the name of the user they are trying to reach.

— If the caller knows the extension of the destination, the caller can enter the extension

to be directly connected.

— An auto-attendant can offer basic menus that allow a user to navigate through themenus by pressing a key.

— Applications offering information only, for example, movie showing limes on amovie hotline.

• Interactive voice response (IVR) capabilities: IVR allows a caller to select options froma voice menu and to interact with the IVR system. After the IVR system plays aprerecorded voice prompt, the caller presses a number on a telephone keypad to select anoption. Eor example, customers dial an enterprise hotline and IVR enables callers to runqueries to gather information from a customer database or to press a number on the dial padto be connected to a particular agent.

Support for fax messages: Inbound fax capability is provided by using a combinationofthe native 1.37 fax processing on Cisco Integrated Service Routers that arc combined withthe message management of Cisco Unit; Express. Users can receive faxes using a directinward dialing (DID) number for each user, and send the fax as a Tagged Image FileEormat (T1EE) attachment to a defined mailbox.

Sur\i>able Remote Site Voicemail: Survivable Remote Site Voiccmaii (SRSV) workswith Sun iv able Remote Site Telephony (SRST). SRST provides remote site telephony, forexample, if a central call processingengine at the headquarters is not operational or theWAN link is broken. After the failure is delected, the IP phones register with the SRST ofCisco 1:nilled Communications Manager Express SRST router.

A deplovment of Survivable Remote Site Voicemail requires a Cisco Unified MessagingGatewav (Cisco UMG) and the relevant licenses. When the WAN connection is up, CiscoUnity Express is provisioned by the Cisco UMG and is not actively used. The Cisco UMGsends the provisioning information to each Survival Remote Site Voicemail site andmaintains any changesat the headquarters and branch locations. Whenthe WANconnectivitv fails. Cisco Unit} Express processes calls the centralized voice-mail system orauto-attendant locally.

Cisco Enitv Express storesall voicemailsduringthe WAN outage. When the connection isrestored, the messages are sent to the centralized Cisco Unity Connection. Cisco UnityExpress goes back in waiting mode. Survivable Remote Site Voicemail supports thefollowing features: subscriber greetings and spokennames, distribution lists,messagewaiting indication, or message notification.

Introducing Cisco Voice and Unified Communications Administration (ICOMM) vS.O © 2010 Cisco Systems. Inc

A migration from a physical Cisco Unified Communications Manager server to a virtualmachine can be done via the DRF. A backup from a Cisco Unified Communications Managerserver can be restored in a VM. A mixture of physical and virtual servers (virtual machines) issupported, which allows an easy migration process.

A VM uses the same licensing process as a physical server. Unlike the physical servers, aspecial license MAC is used. The license MAC is a hash of a set of data on the server, which ishashed to produce a 12-digit hexadecimal string that looks like a MAC address. The licenseMAC can be obtained from the web interface or the CLI, using the command show status.

Other Cisco Unified Communications applications that arc supported on Cisco UCS are thefollowing:

• Cisco Unity Connection version 8.0

• Cisco Unified Presence version 8.0

• Cisco Unified Mobility Advantage version 8.0

• Cisco Unified Contact Center Enterprise version 8.0

TFTP Server

Each Cisco I inified Communications Manager server is defined as a publisher or subscriber atthe time of the installation. Within a Cisco Unified Communications Manager cluster, there canonlv beone publisher, butup to eightsubscribers running theCisco CallManager Service.

ForIPphone registration redundancy, up to three Cisco Unified Communications Managerscan be networked together in a Cisco Unified Communications Manager Group. In addition, thefourth registration option can be an SRST router.

A cluster is built from two or more Cisco Unified Communications Manager servers networkedtogether to provide sen, ices to endusers, which allows support of more enddevices andprov idesredundancy andcentralized administration. Some Cisco Unified CommunicationsManagers in a cluster prov idebasic phone call processing, such as call routing, signaling,phone features, and dial plan administration. Other Cisco Unified Communications Managerscan provide services such asTE1 I',conferencing, music onhold(MOII), and others.

The decision on how many subscribers arc addedto the Cisco Unified CommunicationsManagercluster depends on the following factors:

• Backup requirement in case of failure (redundancy)

• Splitting the load between servers(load sharing)

• How main phones will be supported in the network (scalability)

Inaddition to thepublisher and subscribers, a dedicated IFTP server is recommended forCiscoUnified Communications solutions with more than 1250 users.

Database Replication and User-Facing FeaturesThe figure describes the Cisco Unified Communications Manager database replication process.

Database Replication and User-FacingFeatures

IBM Informix Database:

- Owned by the publisher.

• One-way replication.

• Allchanges are made on thepublisher.

- Ifthe publisher is down

- User-fadngfeatures(UFF),such as call forwarding, etc.,are changed on the activesubscriber.

- Changes to the subscriber arereplicated to the olher serversin the duster.

• When the publisher is back, thesubscriber synchronizes thechangesto the publisher.

Acluster isdefined asany number ofCisco MCS servers that share the same Structured QueryLanguage (SQL) database. An SQL cluster consists ofone primary server that is called a firstnode orpublisher. This server isloaded first during the installation process. The server softwareis loaded in such a way that the SQL Server application takes onthe responsibility formaintaining and replicating the database. The other servers inthe cluster are loaded assubsequent nodes orsubscribers tothe database contained in the first node.

The publisher usually makes changes in the SQL database. The other servers in the cluster havecopies of thedatabase thatareread-only copies.

An exception is a replication ofthe user-facing features during the time a publisher is down.Eor example, call forwarding, message waiting, and other user-facing features are changed onthesubscriber server towhich the IPphone is registered. These changes arethen replicated toall servers in the cluster.

Any user-facing feature data changes made tothe subscriber database are sent tothe publisher.The changes are written tothe database ofthe publisher and are then made available to thesubscribers. This information is replicated to thesubscribers at regular intervals. Thesubsequent nodes contact the first node and ask for any changes. Ifchanges have been made tothe database, thepublisher makes thechanges available to thesubscribers at thattime.

Intracluster Communication

The figure describes the intracluster communication between the nodes in a Cisco UnifiedCommunications Manager cluster.

Intracluster Communication

Intracluster CommunicationSignaling (ICCS) replicatesrun-time data like registrationof devices to all nodes runningthe Cisco CallManagerService

Call Detail Records (CDRs)and Call Management Records(CMRs) are collected by thesubscribers.

The data is periodicallyuploaded to the publisher.

Billing system connects onlyto the publisher.

fhere are two primarv kinds of intraclustcr commtinications. or communications within a CiscoUnified Communications Manager cluster. Thev are as follows:

• Intracluster Communication Signaling (ICCS) involves the propagation andreplication ofrun-time data such as registration of devices, location bandwidth, and shared mediaresources. This information is sharedwith all members of a clusterrunning the CiscoCallManager Service, andit ensures theoptimum routing of callsbetween members of thecluster and associated gatewav s. ICCS runs on TCP ports 8002 to 8004.

• Call Detail Records (CDRs) and Call Management Records (CMRs), when enabled on allservers, are collected bv the subscriber and uploaded to the publisher periodically. During aperiod during which the publisher is unreachable, the CDRs and CMRs are stored on thelocal harddisk of the subscriber. Whenconnectivity is re-established with the publisher, alloutstanding CDRs arc uploaded to the publisher, which stores the records in the CiscoUnified Communications ManagerCDR Analysis and Reporting(CAR) database.

Cisco Unified Communications Manager Data StreamsThe figure describes Cisco Unified Communications Manager data streams and how thedifferent components interactwith each other.

Cisco Unified CommunicationsData Streams

Signaling and session control flows between Cisco Unified CM" and the IPphone and between Cisco Unified CM and the PSTN gateway.

The audio stream is terminated by the PSTN gateway.

PSTN Gateway

fvludsa Exchange

• Unified CM = Cisco Unified Communications Manager

Cisco Unified Communications Manager uses SIP or SCCP to communicate with IP phones forcall setup and control tasks.

SIP supports protocol extensions, so that applications can support advanced features and canstill intemperate with other less functional applications. Here is an example: Three colleaguesare on a conference call. Two of them are at a headquarters location where their SIP-enabled IPphones support video capabilities; the third is at a remote office that docs not support\ ideophones. SIP will establish the conference among the three users, enabling the videoportion for the two users whose equipment supports it. The third user will participate withaudio only. This approach is a shift from the "least-common denominator1 approach in whichonly functions supported by all users are implemented (in which case, none of the colleagueswould be able to use video).

When the call is set up. media exchange occurs directly between the IP phones using RTP tocarry the audio.

In the figure, user A on IP phone A (left telephone) wants to make a call to user B on the PSTNphone (right telephone). In this case, dialed digits are sent to Cisco Unified CommunicationsManager, the call-processing engine. Cisco Unified Communications Manager routes the call tothe PSTN gateway, which uses the Media Gateway Control Protocol (MGCP). H.323. or SIPfor signaling and session control. When user B accepts the call, the RTP media path opensbetween IP phone A and the PSTN gateway, which terminates the RTP stream and converts thestream to the time-division multiplexing (TDM) network.

Cisco UnityConnection will preserve the majority of the end-user functionality, including voice calls,HTTP requests, and IMAP requests, but lower port capacity will be available for taking voicecalls.

One Cisco Unitv Connection server will be designated as the publisher node or "primary" in theserver pair. The other server will be designated subscriber node or "secondary" in the serverpair. The role separation will be consistent with the Cisco Unified Communications Managerclustering scheme, in which there is always one publisher and multiple subscribers. However,only two Cisco Unitv Connection servers are supported in the active-active model. Each CiscoUnitv Connection server maintains its own directory and message database.

A Cisco Unitv Connection active-active high-availability server (Cisco MCS-7845) pair willsupport up to 20.000 mailboxes with 20.000 voice-mail subscribers.

Each Cisco MCS-7845 server can support up to 250 voice-mail ports, for a cumulative total of500 voice-mail ports when both servers are active. If only one server is active, then portcapacity is lowered to a maximum of 250 ports. When installing an active-active high-availability server pair, two types of servers can be defined—a publisher and a subscriber.These terms are used to define the database relationship during installation. When installing thesubscriber in an active-active high-availabilitypair, the IP address or hostname of the primaryor publisher server must be av ailable. After the software is installed, the subscriber willsubscribe to the publisher to obtain a copy of the database and message store.

Cisco Unified Presence OverviewThis topic describes an overview of Cisco Unified Presence.

Cisco Unified Presence Overview

The capabilities of Cisco Unified Presence are:• Presence awareness

• Up to 15,000 users per cluster

• Enterprise Instant Messaging

» Interdomain federation with SIP or XMPP*

• Peer-to-peer file transfer

• Message compliance

• Secure messaging

• Cisco Unified Mobility Advantage integration

•XMPP = Extensible Messaging and Presence Protocol

The main component of Cisco Unified Presence is presence awareness, which means that thecurrent presence status can be derived from automatic events such as computer login andtelephone off-hook. Presence awareness can also be derived from explicit notification eventsfor changing status, such as the user selecting Do Not Disturb (DND) from a change-status picklist. The user availability status indicates whether the user is actively using a particularcommunications device, such as a phone. Communications capabilities of users indicate thetypes of communications that the user is capable of using, such as video conferencing, webcollaboration, or audio. In a Cisco Unified Presence cluster, up to 15.000 users can be added.

Cisco Unified Presence incorporates the Jabber Extensible Communications Platform (XCP),which enables an industry-standard collaboration between different user clients. Withinterdomain federation, the Cisco Unified Presence domain can be federated to other domains,

like Google Talk or WebEx Connect, based on SIP or Extensible Messaging and PresenceProtocol (XMPP). With the XCP platform, a significant amount ol new instant messaging (IM)functionality is available in Cisco Unified Presence, for example, peer-lo-peer file transfer.

Many industries require that instant messages adhere to the same regulatory complianceguidelines as all other business records. To comply with these regulations, the Cisco UnifiedPresence system must log and archive all business records, and the archived records must beretrievable.

Cisco Unified Presence provides support for IM compliance by collecting data for thefollowing IM activities in single cluster, intercluster, or federated network configurations:

• Point-to-point messages

• Group chat, which includes ad hoc. temporary, and permanent chat messages.

OverviewThis lesson introduces the characteristics of Cisco Unified Communications solutions, the

components that are required in a convergent network, the differentVoIPsignaling protocols,quality of service issues, and media transmission protocols. It also gives an overview oftraditional voice networks.

"mm ObjectivesUpon completing this lesson,you will be able to describethe characteristics of a Cisco UnifiedCommunications solution and what needs to be considered when sending voice over packet-

__ based networks. This ability includes being able to meet these objectives:

• Describe how traditional voice networks work and give a short overview of the components

Overview of Traditional Voice NetworksThis topic describes the characteristics of a traditional voice network. It is critical to understandthe function of these traditional telephony components to successfully deploy a VoIP-basedsvstem.

Traditional Voice Networks

A traditional PBX consists of several components, like control cards, slationcards, and trunk cards

Various types of telephone circuits are terminated on different types of cards.

A PBX uses its ovwi cabling environment for carrying the electrical signalthrough wiring closets to the endpoints.

Digital phones connected to PBXs are typically proprietary

CO" Switch

Analog or Digital 8j| PSTNTrunk

j^ Analogor»&r DigitalPhones

PBXs come in various sizes, from 20 to 20.000 stations. The selection of a PHX is important lomost companies because a PBX has a typical life span of 7 to 10 years. All PBXs offer astandard. ba»ic set of calling features. Optional software provides additional capabilities.

A traditional business phone svstem is composed of multiple components. The figure showsthese components and includes the following:

• Telephones: There are two types of telephones that are used in a traditional businesstelephonv network as follows:

— Analog telephones: These phones have a direct connection to the PBX.

— Digital telephones: These phones convert analog voice lo a digitized stream andconnect to a PBX.

• PBX: A PBX is a private!; owned switch that is located on the customer premises.

• Voice mail: A voice-mail svstem is either integrated in the PBX, or can be connected overa digital proprietary circuit.

• Trunk: A trunk provides the path between two switches. Common trunk types include thefollowing:

— "fie trunk: A dedicated circuit that connects PBXs to each other or lo music on hold

(MOID svstems,

—• CO trunk: A direct connection between a local central office (CO) and a PBX. Theconnection mav be digital or analog.

Analog CircuitsIbis figure describes the different analog circuits that can be used with Cisco routers.

Analog Circuits

FXS ports are used to:• Connect analog phones or fax devices

• Provide power, call progress tones, and dial tones• Emulatethe CO switchtotheattached devices

FXO ports are used to:• Connect to office equipment

• Make and receive calls from the PSTN

E&M ports are used to:• Connect to external MOH sources

• Create tie-lnes to PBX systems

Analog voice port interfaces connect routers inpacket-based networks to two- orfour-wireanalog circuits in telephony networks. Two-wire circuits connect toanalog telephone or faxdevices, and four-wire circuits connect to PBXs. Connections to the public switched telephonenetwork (PSTN) CO aretypically made with digital interfaces, 'fherearethree types of analogvoice interfaces that Cisco gateways support:

• Foreign Exchange Station (FXS) interfaces: An FXS interface connects the router oraccess server to end-user equipment suchas telephones, fax machines, or modems. TheFXS interface supplies ring, voltage, anddial toneto the station and includes an RJ-I tconnector for basic telephone equipment or PBXs.

• Foreign Exchange Office(FXO) interfaces: An FXO interface is used for trunkconnections to a PSTN CO or to a PBXthat does not supportor need digital signaling. Astandard RJ-11 modular telephone cable connects the FXO voice interface cardto thePSTN or PBX through a telephone wall outlet.

• Ear and mouth (E&M) interfaces: Trunk circuitsconnect telephone switchesto oneanother: they do notconnect end-user equipment to the network. Themostcommon formof analog trunk circuit is the E&M interface, which uses special signaling paths that areseparate from thetrunk audio pathto convey information aboutthecalls.

Digital CircuitsThis figure describes the different digital circuits that can be used with Cisco routers.

Diqita! Circuits

For enterprise networks, digital circuits are typically-used to connect to the PSTN:

* Bearer channels are used for the transport of data or voice;data channels are used for signaling information.

* Digital circuits are used to conned to the PSTN or for trunkstoother PBXs.

* Time division multiplexing is used on digital circuits.

- Signaling is Channel Associated Signaling (CAS) or CommonChannel Signaling (CCS).

T1, El.orBRIPSTN

Digital voice ports are used in traditional PBX deployments andpacket voice networks, mainlyto connect to thedigital, circuit-switched telephone network, or to traditional PBXs. Thedigitalvoice port interfaces thatconnect the router or access server to Tl, FT, or ISDN BRI lines passvoice data and signaling between the packet network and the circuit-switched network.

There are three tvpes of digital voice circuits that aresupported on Cisco voice gateways asfollows:

• Tl: Usestime-division multiplexing (TDM) to transmit digitaldata usingchannelassociated signaling (CAS) or common channel signaling (CCS).

• F.I: Uses I DM to transmit digital data over 30 voice channels using CAS or CCS.

• BRI: Commonlv used in hurope for smaller branch offices lo provide digital connectionsto the CO switch with two bearer (B) channels and one data (D) channel, using CCS.

• Supports media flow-through (default) and media flow-around

• Provides codec negotiation and video integration

A lelco prov ider can connect the enterprise to the PSTN with VoIP trunks. VoIP trunks areeasyto configure. Whencomparing VoIP trunkswith traditional trunks, such as a digitalTl or Tlcircuit, the following characteristics can be outlined:

• Cost savings areone of the biggest benefits of VoIP trunks because thecostper line istypically lesswith VoIP trunks than with traditional circuits. VoIP trunks typically alsohave lower rates for long distance.

• VoIP trunks can use the bandw idth that is guaranteed to the voice traffic for data whenvoice is not utilizing the bandwidth. This procedure requires properimplementation ofquality of service (QoS).

• Internet telephony service provider (fl'SP) trunks are usually Session Initiation Protocol(SIP) based, although the ITSP can use 11.323.

Cisco Unified Border Element is a demarcation point. Cisco IInified Border Flement providescall routing, signaling, andcall control capabilities between twoVoIP networks. Forexample,it prov ides thesecapabilities between an enterprise and a VoIP providernetwork orinterconnects two enterprise networks.

Cisco Unified BorderFlementterminates and reoriginates both signaling (11.323 and SIP) andmedia streams Real-Time Transport Protocol (RTP)and Real-Time Transport Control Protocol(RTCP) while performing border interconnection services between IP networks. Cisco UnifiedBorderFlementwas formerly known as Cisco Multiservice IP-to-lP Gateway. Cisco UnifiedBorder Flement. in addition to other Cisco IOS Software features, includes Session BorderController (SBC) functions that helpenableend-to-end IP-based transport of voice, video,anddata between independent unified communications networks.

Cisco Unified Border Flementcan process calls that arc controlled by SIP or 11.323. Thisprocessing also includes the ability lo interconnect VoIPnetworks usingdifferentsignalingprotocols as follows:

VoIP Protocols

This table describes the different VoIP protocols (hat are used in aconverged network.

VoIP Protocols

intraditional networks, different signaling protocols exist fordevice control in an IP-based network:

H.323

SIP

MGCP

SCCP

ITU standard protocol for interactive conferencing;evolved from H.320 ISDN standard; decentralized diatplan

IETF protocol for nteractive and non interactiveconferencing;decentralized dalplan

IETFstandard for PSTN gateway control; centralizeddialplan

Cisco proprietary protocol used between Unified CM andIP phones or to controlFXS ports

VoIP uses several control signaling protocols and call signaling protocols:

• H.323: 11.323 is a standard that specifies the components, protocols, and procedures thatprov ide multimedia communication services—real-time audio, video, and datacommunications—over packet networks, including IP networks. H.323 is part ofa familyof ITU-1 recommendations that arccalled 11.32\ that provides multimedia communicationservices o\er various networks. It is actually an umbrella of standards (bat define allaspects of synchronized voice,video, anddata transmission. It also definesend-to-end callsignaling. With H.323. gateways can be used for digit translation ormanipulation and areable toroute calls onspecific rules. The use ofgateways for digit translation andmanipulation is called adecentralized dial plan. For example, an H.323 gateway in adifferent country can have other digit manipulation rules to match national dial planrequirements.

• SIP: SIP is adetailed protocol that specifics the commands and responses to set up and teardown calls. SIP also provides features such as security. SIP and its partner protocols.Session Announcement Protocol (SAP) and Session Description Protocol (SDP). provideannouncements and information about multicast sessions to users on a network. SIP definesend-to-end call signaling between devices. SIP is atext-based protocol that borrows manyelements of HIIP. using the same transaction request and response model and similarheader and response codes. It also adopts amodified form ofthe UR1. addressing schemethat is used within email, which is based on Simple Mail Transfer Protocol (SMTP). SIP isalsoused to prov idedecentralized dial plan features.

1-44 Introducing Cisco Voice and Unified Communications Administration (ICOMM) vS.O '2010 Cisco Systems, Inc

Media Gateway Control Protocol (MGCP): MGCP is amethod for PSTN gatewaycontrol or thin dev ice control. Specified in RFC 2705. MGCP defines aprotocol thatcontrols VoIP gateways that are connected to external call control devices, which arereferred to as call agents. MGCP provides the signaling capability for less expensive edgedevices, such as gateways, which may not have acomplete voice-signaling protocol such asH.323 implemented. For example, any time an event such as off hook occurs at the voiceport of agatewav. the voice port reports that event to the call agent. The call agent thensignals that device to provide aservice, such as dial-tone signaling, With MGCP, all callrouting decisions are made by the central call processing unit, for example, the CiscoUnified Communications Manager. This process allows centralized management ofcallrules and digit manipulation toprovide a central dial plan.

Skinnv Client Control Protocol (SCCP): SCCP isaCisco proprietary protocol that isusedbetween Cisco Unified Communications Manager and Cisco VoIP phones. The end stations(telephones) that use SCCP are called skinny clients, which consume less processingoverhead. SCCP can also be used tocontrol FXS ports in a router loprovide supplementaryfeatures.

Digital Signal ProcessorsThis figure describes the function ofdigital signal processors (DSPs

Digital Signaling Processors

The DSP chipperforms sampling, quantization, encoding, andoptional compression.

DSPsare used in both directions to convert from a traditional analogor digital voice signal to VoIP, and vice versa

The numberofsimultaneous calls that a chip can process dependson the type of DSP and the codecs that are being used.

DSPs

PSTNAnalog or Digital IP Packets

IP

DSP chip, for examplePVOM2orPVDM3

A DSP isa specialized microprocessor that isdesigned specifically for digital signalprocessing, DSPs enableCisco platforms to efficiently process digital voice traffic. DSPs on arouterprov ide stream-to-packet signalprocessing functionality that includes voicecompression, echocancellation, andtone- andvoice-activity defection. With the Packet VoiceDSP Module 3(PVDM3) modules. Cisco offers multiple power-saving modes, including apower-saver mode when the module is not in use. In power-saver mode, each PVDM3can saveup to 5 watts of power.

Note PVDM3 modules are not supported ontheexisting Cisco 2800 and3800 Series IntegratedServices Routers.

The fourmajor functions of DSPs in a voicegateway are as follows:

• Transcoding: The direct digital-to-digital conversion from one codec lo another.Transcoding compresses anddecompresses voice streams to match endpoint devicecapabilities. Transcoding is required when an incoming voice stream is digitized andcompressed (witha codec) to save bandwidth. But the local device does not supportthattype of compression. Ideally, all IP telephony devices wouldsupportthe same codecs,butthis is not the case. Rather, different devices support different codecs. Transcoding isprocessed by DSPson the DSPfarm: sessionsare initiated and managed by Cisco UnifiedCommunications Manager. Cisco Unified Communications Manager alsorefers totranscoders as hardware MediaTermination Points(MTPs). If an application or servicecanprocess only one specific codec type, which is usually G.711, a G.729 call from a remotesite must be transcoded to G.71 1.This transcoding can only be done using DSPresources.Because applications and sen icesare often hosted at mainsites. DSPtranscoding resourcesare most common in central sites.

1-46 Introducing Cisco Voice and Unified Communicalions Administration (ICOMM) v8.0 ©2010 Cisco Systems, Inc.

Voice termination: Applies to acall that has two call legs, one leg on atime-divisionmultiplexing (TDM) interface and the second leg on aVoIP connection, fhe IDM legmust be terminated bv hardware that performs coding, decoding, and packctization ol thestream DSPs perform this termination function. ADSP also provides echo cancellation,voice activity detection (VAD). and jitter management at the same time that it performsvoice termination.

-Vudio conferencing: In atraditional circuit-switched voice network, all voice traffic goesthrough acentral device (such as aPBX system), which provides audio conferencingservices as well Because IP phones transmit voice traffic directly between phones, anetwork-based conference bridge is required to facilitate multiparty conferences. Aconference bridge is aresource that joins multiple participants into asingle call. It can ^accept any number of connections for agiven conference, up to the maximum number ofstreams that are allowed for a single conference on that device. There is aone-to-onecorrespondence between media streams that are connected lo aconference and participantsthat are connected to the conference. The conference bridge mixes the streams together andcreates aunique output stream for each connected party. The output stream lor agivenpartv is the composite of the streams from all connected parties minus their own inputstream. Hardware conference bridges are used in two environments. They can be used toincrease the conferencing capacity in acentral site without putting an additional load onCisco Unified Communications Manager servers, which can host software-basedconference bridges. More important, hardware conference bridges are also used in remotesites. Ifno remote-site conference resources are deployed, every conference will be routedtocentral resources, which sometimes results inexcessive WAN usage.MTP: An entitv that accepts two full-duplex voice streams using the same codec. It bridgesthe media streams together and allows them to be set up and torn down independently. Thestreaming data that is received from the input stream on one connection is passed to theoutput stream on the other connection, and vice versa. In addition, the MTP can be used totranscode a-law to mu-law and vice versa, oritcan be used to bridge two connections thatutilize different packctization periods (different packet sizes). MTPs are also used toprovide further processing ofacall, for example. DTMF conversion. There are severalmethods for sending DTMF over IP. Two communicating endpoints might not support thesame DTMF format. In these cases, an MTP in the media path can convert DTMF signalsfrom the format ofone endpoint tothe format ofthe other endpoint.

G722offers wideband voice with low DSP processing requirementsiLBC isoptimized for WAN and Internet audio streams (packet loss).iSAC is a wideband codec with high audio quality thatis supportedwith Cisco Unified IP Phone 8900 and 9900 Series and Cisco UnifiedCSF clients.

G 729 can be implementedwith VAD* and CNG"as G.729Annex B.

"VAD- Voice Activity Detection-CNG = Comfort Noise Generation

Acodec is asoftware algorithm that compresses and decompresses speech or audio signals,fhere are many standardized codecs thatarc used in VoIP networks.

G.711 is an ITU-T standard that uses pulse code modulation (PCM) to encode analog signalsinto adigital representation by regularly sampling the magnitude ofthe signal at uniformintervals, and then quantizing it into aseries ofsymbols in adigital (usual! vbinary) code. Thevoice samples created by the PCM process generate 64 kb/s ofdata. This data is carried acrossa network for a G.71 1 call.

G.722 is a I'll '-T standard wideband speech codec operating at48. 56. and 64 kb/s. G.722 istypically used in LAN deployments, where the required bandwidth is not prohibitive, and offersa significant improvement in audio quality over older narrowband codecs such asG.711.without causing an excessive increase in implementation complexity. Cisco UnifiedCommunicalions Manager calculates G.722 with 64 kb/s.

Internet Low Bitratc Codec (iLBC) isa speech codec that is suitable for robust voicecommunication over IP. The codec is designed for narrowband speech and results in apavloadbit rate of 13.3 kb/s. The CPU load is like die CI729A. with higher quality and better responseto packet loss. Ifthere are lost frames. iLBC processes voice quality issues through gracefulspeech quality degradation. Iost frames often occur with lost or delayed IP packets. Ordinarylow-bit-rate codecs exploit dependencies between speech frames, which unfortunately results inerror propagation when packets are lost ordelayed. In contrast. iLBC-encoded speech frame;,are independent and so this problem will not occur.

Internet Speech Audio Codec (iSAC) is awideband speech codec that is robust to packet jitter(delay variation) and packet loss, fhe complexity iscomparable to G.722 at lower bit rales.iSAC has an adaptive and variable bit rate (10 to32 kb/s). Cisco Unified CommunicationsManager calculates iSAC with 32 kb/s.

Introducing Cisco Voice and Unified Communications Administration (ICOMM] v8.0 ©2010Cisco Systems. Inc.

G.729 is the compression algorithm that Cisco uses for high-quality 8-kb/s voice. G.729 is ahigh-complexity, processor-intensive compression algorithm that monopolizes processingresources.

Although G.729A is also an 8-kb/s compression algorithm, it is not as processor-intensive asG.729. G.729A is amedium-complexity variant of(i.729 with slightly lower voice quality andis more susceptible to network irregularities such as delay, variation, and "tandeming."Tandeming causes distortion that occurs when speech is coded, decoded, then coded anddecoded again, much like the distortion that occurs when avideotape is repeatedly copied.fhe Annex Bvariant ofG.729 is also a high-complexity algorithm that adds VAD and comfortnoise generation (CNG) to the codec. VAD detects silence that occurs in typical conversations.This silence is present when one end is talking and the other is listening. The listening end canhave the RTP stream that is going toward the talker temporarily suppressed. The benefit ofthissuppression is an approximate 35 percent savings in bandwidth. The RTP stream is reactivatedupon the detection of sound on the listening end, which can cause clipping of the first syllablewhen the RTP stream restarts. With traditional voice circuits, users are used tohearing whitenoise. When users switch todigital circuits, the lack ofwhite noise can bemistaken for adisconnection. CNG inserts white noise into the line loaccommodate users who are changingfrom traditional voice circuits.

G.729AB is a medium-complexity variant ofG.729B with slightly lower voice quality.

RTP and RTCP

This figure describes the difTcrent protocols for transporting voice and video traffic over an 1P-hascd network.

RTP and RTCP

RTP provides end-to-end delivery sen/ices fordelay-sensitivedata, such as voice and video.

Randomly picks even ports from UDP port range 16384 lo32767.

RTCP provides out-of-band statistics and control information.

The data flow is paired with the RTP stream and uses thesame port as the RTP stream plus 1.

RTP prov ides end-to-end network transport functions that are intended for applicationstransmitting real-time requirements, such as audio and video. Those functions include payload-typc identification, sequence numbering, time stamping, and delivery monitoring. RTPtypically runs in addition to User Datagram Protocol (UDP) so that itcan use the multiplexingand checksum sen ices of that protocol. RIP does not have a standard TCP or UDP port onwhich it communicates. The only standard that it obeys is that UDP communications arc doneusing an even port, and the next higher odd port is used for RTCP communications. Althoughthere arc no standards that are assigned. RTP isgenerally configured to use ports 16384 to32767.

RIP is frequently used with Real Time Streaming Protocol (RTSP) in streaming mediasystems. RTP isalso used with H.323 or SIP in videoconferencing and push-to-talk systems,this wide applicability makes RTP an essential part ofa VoIP technical foundation. RTP goesalong with RTCP. and it is built in addition to UDP. Applications that use RTP arc lesssensitive to packet loss butare typically very sensitive to delays, so UDP is a better choice thanTCP for such applications.

RTP is a critical component of VoIP because it enables the destination device to reorder andretime the voicepackets before they are playedout lo the user. An RTP headercontains a timestamp and sequence number, which allows the receiving device lo buffer and to remove jitterand latency by sv nchronizing the packets to playback a continuous stream of sound. RTP usessequence numbers to orderthe packets only. RTP doesnot request retransmission if a packet islost.

1-50 Introducing Cisco Voice and Unified Communications Administration (ICOMM] v8.0 ©2010 Cisco Systems, Inc.

RTCP provides amechanism for hosts that arc involved in an RTP session to exchangeinformation about monitoring and controlling the session. RTCP monitors the quality olZents such as packet count, packet loss, delay, and jitter. RTCP transmits packets as apercentage of session bandwidth, but at aspecific rate of al least every 5seconds.SR rP encrypts the RTP data in both unicast and multicast applications. SRTP uses AdvancedEncryption Standard (AES). for audio stream encryption.

Overview of Packet-Oriented NetworksThis topic describes the advantages ofapacket-oriented network.

Packet Requirements

Diliereni data has different requirements. Voice traffic usually generates asmooth demand onbandwidth and has minimal impact on other traffic as long as the voice traffic is managedWhile voice packets are typically small (60 to 200 bytes), they cannot tolerate delay or drops.1he result ofdelays and drops are poor, and often unacceptable, voice quality,fhe QoS requirements for data traffic vary greatly. Different applications may make verydifferent demands on the network—for example, a human resources application versus anautomated teller machine application. Even dilfercnl versions ofthe same application mav havevarying network traffic characteristics.

While data traffic can demonstrate cither smooth or bursty characteristics depending upon theapplication, data traffic differs from voice and video in terms ofdelay and drop sensitivity.Almost all data applications can tolerate some delay and generally can tolerate high drop'ratcs.Because data traffic can tolerate drops, the retransmit capabilities of TCP become important. Asa result, many data applications use TCP.

In enterprise networks, important (business-critical) applications are usually casv lo identifv.Most applications can be identified based on TCP or UDP pott numbers. Some applications usedynamic port numbers that, to some extent, make classifications more diflicull. Cisco IOSSoftware supports Network-Based Application Recognition (NBAR). which can be used torecognize dynamic port applications.

Videoconferencing applications also have stringent QoS requirements very like therequirements for voice. Hut videoconferencing traffic is often bursty and greedy in nature and.asa result, can impact other traffic. Therefore, it isimportant lounderstand thevideoconferencing requirements for anetwork and to provision carefully for thoserequirements.

Advantages and Drawbacks of Packet-Oriented Networksfhere are several advantages and drawbacks that are presented in packet-oriented networks.

Advantages and Drawbacks of Packet-Oriented Networks

Merging different traffic streams to a single network canlead to a number of service-quality issues:• Lack ofbandwidth: Multiple, simultaneousflows compete fora

limited amount of bandwidth.

• Delay issues: End-to-end delay occurswhen packets musttraverse manynetwork devices and linksthat add up to theoverall delay.

• Jitter: The variability oftimethat packets need through thenetwork is called "jitter," which occurs as a result ofdifferentnetwork load or paths.

• Packet loss: Packets might be dropped when a link is congested.

The four biggest problems facing converged enterprise networks are asfollows:

• Lack of bandwidth: Merging different traffic streams to an IP-based network can lead tobandwidth capacity problems—for example, large graphics files or multimedia users.Increased useof voice andvideo endpoints canalso cause bandwidth capacity problemsover data networks.

• Delay issues: Delay isthe time that it takes for a packet toreach the receiving endpointafter being transmitted from the sending endpoint. This time iscalled the "end-to-enddelay." and consists of two components:

— Fixed networkdelay: Two types of fixed delays areserialization and propagationdelays. Serialization isthe process ofplacing bits onthe circuit. The higher thecircuit speed, the less time it takes toplace the bits onthecircuit. Therefore, thehigher the speed of the link, the less serialization delay isincurred. Propagationdelay is the time that il lakes for frames to transit the physical media.

— Variable network delay: Processing delay is a type of variabledelay, and is thetime required for a networking device to look uptheroute, change the header, andcomplete other switching tasks. Insome cases, thepacket must also bemanipulated—for example, when the encapsulation type or the hop count must bechanged. Each of these steps can contribute to theprocessing delay.

• Jitter: Jitter is the della. or difference, in the total end-to-end delay values of two voicepackets inthe voice flow. Jitter occurs asa result ofdifTcrent network paths ordifferentnetwork load.

• Packet loss: Loss of packets is usually caused by congestion in the WAN, resulting inspeech dropouts ora stutter effect if the playout side tries toaccommodate by repeatingprevious packets.

Quality of Service RecommendationsThis figure describes the different QoS recommendations for voice and video traffic.

QoS Recommendations

Voice and video traffic has extremely strict QoS requirements:

QoS issues i Recommendation

Latency < 150 ms

Jitter <30ms

Loss <1 %

Bandwidth requirements for voice and video depend on thecodec and overhead.

Video streams need an additional 20 percent bandwidth.

Voiceand video packets can tolerate no more than a 150-ms delay (G.114 one-wayrequirement) and less than one percentpacket loss. Jitterdelay shouldnotexceed 30 ins.

Depending on the codec and Layer 2 protocol, a typical voice call will require 17 to 106 kb/sofguaranteed priority bandwidth plus an additional 150b/s per call for voice-control traffic.Multiplying these bandwidth requirements limes the maximum number of calls dial areexpected during the busiest time period will provide an indication of the overall bandwidth thatis required for voice traffic.

The minimum bandwidth fora videoconferencing stream wouldrequire the actual bandwidth ofthe stream (dependent upon the typeof videoconferencing codecbeing used)plussomeoverhead. Torexample, a 384-kb/s video stream would actually require a total of 460 kb/s ofpriority bandwidth,

Link Fragmentation and InterleavingThis figure describes the link fragmentation and interleaving mechanism.

Link Fragmentation and Interleaving

• 1500 bytes need 214 mstobetransmitted ona 56 kb/s link.• Frames are fragmented into smaller packets.• Fragmented packets are interleaved tominimize thedelay.• Used for Multilink PPP or Frame Relay.

* Traffic increases due to more frame overhead.

Frame Relay

mData lO

FRF. 12

Link fragmentation and interleaving (LFI) are a Layer 2 techniques inwhich large frames arebroken into smaller, equally sized fragments, and transmitted over the link inan interleavedfashion with more latency-sensitive traffic flows (like VoIP). Using LFI, smaller frames areprioritized, and a mixture offragments is sent over the link. LFI reduces the queuing delay ofsmall frames because the frames are sent almost immediately. Link fragmentation, therefore,reduces delay and jitter by expediting the transfer ofsmaller frames through the hardwaretransmit (Tx) queue. The LFI methods available include Multilink PPP (MLP), Frame RelayFragmentation Implementation Agreement (FRF.12), and FRF.I I Annex C.

Note LFI is nota technique to save bandwidth. Every newsmaller, equally sized fragment has itsown new header, which increases the overall required bandwidth.

Compression MethodsI'his figure describes the different compression methods.

Compression Methods

Header Compression

Used to compress RTP headers for efficient real-time transport ofdata.

Performed on a link-by-link basis

Reduces size of voice packet headers from40 bytes to 2 or 4 bytes(CRC)

G 729 calls over Frame Relay can be reduced from 28 kb/s to 14 kb/s

Payload Compression

CPU-intensive task that may add per-packet delay.

Advantage depends on the complexityof the payload compressionalgorithm.

RI P includes a dataportion anda header portion. Thedataportion of RTP is a thinprotocolthat provides support for the real-time properties of applications, such as continuous media,including timing reconstruction, loss detection, andcontent identification. Theheader portionof RTP is considerably largerthan the dataportion.The headerportion consists of an IPsegment, a UDP segment, andan RTP segment. Given the size of the IP/UDP/RTP segmentcombinations, it is inefficient to send the IP/UDP/RTP headerwithoutcompressing it.

Theminimum 20 bytes of the IPsegment that is combined with the8 bytes of the UDPsegment and the 12 bytes of the RTP segment, create a 40-byte IP/UDP/RTP header. The RTPpacket has a pav load of approximately 20 to 160bytes for audioapplications that usecompressed pay loads.

The RTP header compression feature compresses the IP/UDP/RTP header in an RTP dalapacket from 40 bytes to approximately 2 to 4 bytes.

RTPheadercompression accomplishes majorgains in terms of packetcompression becausealthough several fields in the header change in every packet, the difference in header fields (forexample, the Sequence Number) duringan RTP stream from packet to packet is often the sameand predictable. Therefore, the second-order differenee is zero.The decompressor canreconstruct the original header without any loss of information.

RIP header compression also reduces overhead for multimedia RTP traffic. The reduction inoverhead results in a corresponding reduction in delay. RTP header compression is especiallybeneficial when the RIP pay load si/c is small, for example, for compressed audio payloads of20to50bvtes.

1-56 Introducing Cisco Voice and Unified Communications Administration (ICOMM) v8.0 ) 2010 Cisco Systems, Inc.

RTP header compression can be used for media-on-demand and interactive services such asInternet telcphonv. RTP header compression provides support for real-time conferencing olgroups of anv si/'c within the Internet. This support includes source identification support lorgatevvav ssuch as audio and video bridges, and support for multicast-to-un,cast translators. RI Pheader compression can benefit both telephony voice and multicast backbone applicationsrunningover slow links.Usin* RTP header compression on any high-speed interfaces—that is. anything over Tlspeed—is not recommended. Any bandwidth savings that is achieved with RTP headercompression may be offset by an increase in CPU utilization on the router.Laver 2pavload compression is aCPU-intensive task and can add per-packet compressiondelav due to the application of the compression method to each frame. The serialization delay,however, is reduced because the resulting frame is smaller. Serialization delay is the fixeddelav that is required to clock the frame onto the network interface. Depending on thecomplexity of the Layer 2payload compression algorithm, overall latency might be reduced,especially on low-speed links.Cisco routers support hardware-assisted compression to reduce the CPU load and the Layer 2payload compression delay.

Quality of Service ModelsThis figure describes the different quality ofservice models.

Quality of Service Models

There are three different models for deploying QoS in anetwork:

• Best-effort model

No QoS applied to packetsDefault model for all traffic

* Integrated Services model (IntServ)Offers absolute QoS guarantees by explicitly reservinqbandwidth

Uses RSVP to reserve network resources* Differentiated services model (DiffServ)

Allows classification of network traffic

QoS policy enforces differentiated treatmentof traffic classesMany levels ofqualitypossibleCommonly used in enterprise networks

There are three different models av ailable for deploying QoS in a packet-oriented network:• Best-effort: With the best-effort model. QoS is not applied to packets. Ifit is not important

when orhow packets arrive, the best-effort model isappropriate. Best-effort isthe defaultfor all router models if noQoS isdeployed.

• Integrated Services (IntServ): IntServ can provide very high QoS to IP packets.Essentially, applications signal to the network that they will require special QoS for thattime and that bandw idth is reserved. With IntServ. packet delivery is guaranteed. Ilowever.the use ofIntServ can severely limit the scalability ofanetwork. IntServ is amultiple-service model that can accommodate multiple QoS requirements. IntServ inherits theconnection-oriented approach from telephony network design. Hvery individualcommunication must explicitly specify its traffic descriptor and requested resources tothenetwork. Ihe edge router performs admission control loensure that available resources aresufficient in the network. Tiie IntServ standard assumes that routers along apath set andmaintain the state for each individual communication.

fhe role of RSVP inthe Cisco QoS architecture islo provide resource admission controllor VoIP networks. Ifresources are available. RSVP accepts a reservation and installs atraffic classifier in the QoS forwarding path. The traffic classifier tells the QoS forwardingpath how to classify packets from aparticular flow and what forwarding treatment toprov ide.

In the IntServ model, the application requests a specific kind ofservice from the networkbefore sending data. The application informs the network ofits traffic profile and requests aparticular kind ofsenice that can satisfy its bandwidth and delay requirements. Theapplication isexpected tosend data only after it gets a confirmation from the network. Theapplication is also expected to send data that lies within its described traffic profile.

Introducing Cisco Voice and Unified Communications Administration (ICOMM) v8.0 ©2010Cisco Systems. Inc.

Differentiated services (DiflServ): DiffServ provides the greatest scalability andflexibility in implementing QoS in anetwork. Network devices recognize traffic classesand provide different levels of QoS to different traffic classes. DilTServ was designed toovercome the limitations ofboth the best-effort and IntServ models. DilTServ can providean "almost guaranteed" QoS. while being cost-effective and scalable still.DiffServ is like aconcept known as "soft QoS.'" With soft QoS. QoS mechanisms arc usedwithout prior signaling. In addition. QoS characteristics (bandwidth and delay, forexample), arc managed on ahop-by-hop basis by policies that are establishedindependently at each intermediate device in the network. The soft QoS approach is notconsidered an end-to-end QoS strategy because end-to-end guarantees cannot be enforced.However, soft QoS is amore scalable approach toimplementing QoS than hard QoS. Many(hundreds or potentially thousands) ofapplications can be mapped into asmall set ofclasses within which similar sets ofQoS behaviors are implemented. Although QoSmechanisms in this approach are enforced and applied on ahop-by-hop basis, uniformlyapply ing global meaning to each traffic class provides both flexibility and scalability.With DiffServ. network traffic is divided intoclasses that arebased on businessrequirements. Each ofthe classes can then be assigned adifferent level ofservice. As thepackets traverse anetwork, each ofthe network devices identifies the packet class andprovides service to the packet according to that class. Many levels ofservice can be chosenwith DiffServ. For example, voice traffic from IP phones is usually given preferentialtreatment over all other application traffic. Email is generally given best-effort service.Nonbusiness traffic can either be given very poor service or blocked entirely.

Quality of Service MechanismsThis figure describes thedifferent quality of service mechanisms.

Quality of Service Mechanisms

• Classification Each class-oriented QoS mechanism mustsupport some type of classification, forexample DSCP.

* Markrno Used to mark packets based on classification,metering, or both.

• Congestion management' Each interface must have aqueuing mechanismto prioritize transmission of packets.

• Congestion avoidance Used to drop packets early to avoidcongestion later in the network.

* Pohong and shaping1 Used to enforce a rate limit based onthe metering. Excess traffic is either dropped, marked, ordelayed.

* Link efficiency Used to improve bandwidth efficiency throughcompression, link fragmentation, and interleaving.

The maincategories of toolsthat are used to implement QoS in a network are as follows:

• Classification and marking: This mechanism involves identifying and splitting of trafficinto different classes and the marking ofirafllc according lobehavior and business policies.Classification can be done using existing and trusted differentiated services code point(DSCP) values on the incoming interface or it can be identified with Network-RasedApplication Recognition (NBAR).

• Congestion management: Thismechanism involves the prioritization, protection, andisolation of traffic that is based on markings. Congestion management can beperformedwith weighted round robin (WRR) and modified deficit round robin (MDRK).

• Congestion avoidance: This mechanism discards specific packets thai are basedonmarkings toavoid network congestion. Common techniques arcrandom early detection(RED) and weighted random early detection (WRI-D).

• Policing and shaping: These aretraffic conditioning mechanisms that police traffic bydropping noncompliant traffic tomaintain network integrity. These mechanisms also shapetraffic to control bursts by queuing traffic.

• Link efficiency: Onetype of linkefficiency technology is packet header compression,which improves the bandwidth efficiency of a link. Another technology is LFI. which candecrease thejitter of voice transmission by reducing voicepacketdelay.

Applying Quality of Service to Input and Output InterfacesThis figure describes how quality of service is applied in apacket-oriented network on inputand output interfaces.

(High-speed to low-speed links oraggregation points)

(Goingto lower-speedlinks or from points ofaggregation)

(Low-speedWAN links)

In aQoS-enabled network, classification is performed on every input interface. Marking shouldbe performed as close to the network edge as possible—in the originating network device, ifpossible. Devices farther from the edge of the network, such as routers and switches, can beconfigured to trust or not trust the markings that are made by devices on the edge of thenetwork. An IP phone, for example, will not trust the markings ofan attached PC, while aswitch will generally be configured to trust the markings ofan attached IP phone.Itmakes sense touse congestion management, congestion avoidance, and traffic-shapingmechanisms on output interfaces. These mechanisms help maintain smooth operation oflinksby controlling how much and which type oftraffic is allowed on alink. On some router andsv'vitch platforms, congestion management mechanisms, such as weighted round robin (WRR).can be appliedon the input interface.

Congestion avoidance is typically employed on an output interface wherever there is achancethat ahigh-speed link or aggregation oflinks feeds into aslower link, for example, a LANfeeding into a WAN.

Policing and shaping are typically employed on output interfaces to control the flow of trafficfrom ahigh-speed link to lower-speed links. Policing is also employed on input interfaces tocontrol the flow into a network device from ahigh-speed link by dropping excess low-prioritypackets.

Both compression and LFI are typically used on slower-speed WAN links between sites loimprove bandwidth efficiency.

Queuing Algorithms

1-62

This figure describes the different queuing algorithms.

Queuing Algorithm:

• FIFO

Firstpacket in is first packet out; onlyone queue• Priority queuing (PQ)

Empty queue 1, if queue 1 isempty, then dispatchpackets fromqueue 2, and so on

• Weightedfairqueuing (WFQ)

Flow-based algonthm that simultaneouslyschedules interactive trafficto the front of a queue

* Class-based weightedfairqueuing (CBWFQ)

• Extends WFQ functionalityto provide support for user-defined trafficclasses

• Low-latency queuing (LLQ)

Bringsstrict PQ to CBWFQ;allows delay-sensitive data like voice tobe dequeued and transmitted before packets inotherqueues aredequeued

Queuing algorithms are the following:

• FIFO: FIFO is the simplest queuing algorithm. Packets are placed into asingle queue andserv iced in the order they were received. All individual queues are, in fact. FIFO queues.Other queuing methods rely upon FIFO asthe congestion management mechanism forsingle queues, while using multiple queues toperform more advanced functions such asprioritization.

• Priority queuing (PQ): 'I he PQ algorithm is also quite simple, liach packet is assigned apriority and placed into a hierarchy ofqueues that are based on the assigned priority. Whenthere are no more packets in the highest queue, the next lower queue isserviced. Packetsare then dispatched from the next-highest queue until either the queue is empty oranotherpacket arrives for a higher PQ.

Packets will be dispatched from a lower queue only vvhen all higher-priority queues areempty. Ifa packet arrives for a higher queue, the packet from the higher queue isdispatched before any packets in lower-level queues.

The problem with PQ is that packets waiting in the lower-priority queues may never bedispatched ifa steady stream ofpackets continues loarrive for aqueue with a higherpriority.

• Weighted fair queuing (WFQ): WFQ is a flow-based algorithm that simultaneouslyschedules interactive traffic to the from ofa queue to reduce response time and shares theremaining bandwidth among high-bandwidth flows in a fair manner. Classificationidentifies a flow and assigns a queueto the flow.

Introducing CiscoVoice and Unified Communications Administration (ICOMM) v8 0 ©2010Cisco Systems, Inc.

Weight is used for scheduling lo give proportionately more bandwidth to Hows with ahigher priority. The tail-dropping scheme is improved so that it drops packets of he mostaggressiv eflows. WFQ uses afixed number of queues. The hash function is used to assignaqueue to aflow. There are eight additional queues for system packets and optional* up to1000 queues for RSVP flows. The number of dynamic queues that are used by WFQ-is bydefault based on the interface bandwidth. Using the default interface bandwidth. WFQ uses256 dynamic queues. The number of queues can be configured in the range between 16 and4096 (the number must bea power of2).Class-based weighted fair queuing (CBWFQ): CBWFQ extends ^e standard WFQfunctionality to provide support for user-defined traffic classes. With CBWPQ. theadministrator defines the traffic classes that are based on match criteria, includingprotocols access control lists (ACLs). and input interfaces. Packets that sal.sty the matchcriteria for aclass constitute the traffic for that class. Aqueue is reserved for each class,and traffic belonging toa class isdirected tothat class queue.After aclass has been defined according lo its match criteria, characteristics can beassigned to it Bandwidth, weight, and maximum packet limit can be assigned tocharacterize aclass. The bandwidth assigned to aclass is the minimum bandwidthdelivered to the classduringcongestion.

To characterize aclass, the queue limit must also be defined for that class, which is themaximum number ofpackets allowed to accumulate in the class queue. Packets belongingto aclass are subject to the bandwidth and queue limits that characterize the class. After aqueue has reached its configured queue limit, enqueuing of additional packets to the classcauses tail drop or random packet drop lo take effect, depending on how the class policy isconfigured.

Low-latency queuing (LLQ): Although WFQ provides afair share ofbandwidth to everyflow and fair scheduling ofits queues, itcannot provide guaranteed bandwidth and lowdelav to selected applications. For example, voice traffic may still compete with otheraggressive flows in the WFQ queuing system because the WFQ system lacks priorityscheduling fortime-critical traffic classes.

The LLQ feature adds strict priority queuing to CBWFQ. Strict priority queuing allowsdelay-sensitive data such as voice lo be dequeued and sent first (before packets in otherqueues are dequeued), giving delay-sensitive data preferential treatment over other traffic.Without LLQ. CBWFQ provides weighted fair queuing based on defined classes with nostrict priority queue available for real-time traffic. CBWFQ allows you lo define atrafficclass andthen assign characteristics to thatclass.

For CBWFQ. the weight for apacket belonging to aspecific class is derived from thebandwidth that has been assigned to the class when itwas configured. Therefore, thebandwidth thai is assigned to the packets ofaclass determines the order in which packetsare sent. All packets are serviced fairly based on weight; no class ofpackets may begranted strict priority. This scheme poses problems for voice traffic, which is largelyintolerant ofdelay, especially variations in delay. For voice traffic, variations in delayintroduce irregularities oftransmission that are heard as jitter in the conversation.

User Management: RolesThis figure describes user role characteristics.

User Management; Roles

Role characteristics;

- Configure end users and application users with different privilege levels:- No access

- Read only (view)

- Full access (view and modify)

• Roles comprise groups of resources (on a menu basis)for anapplication:- Default standard roles (CCM end users, CCM admin users, etc.)

- Custom roles

Each user isassigned with acertain role. Each role comprises certain application resources.Resources in Cisco Communications Manager Adminislration application are assigned withone ofthe following privileges: No Access, Read, and Update (full access). Otherapplications—for example Cisco Extension Mobility or Cisco Unified Serviceability—specifytheir own access privileges to their resources.

Eoreachrolethai is associated with theCisco Unified Communications ManagerAdministration application, one ofthese privilege levels applies for access to each oftheresources. The access privileges specify thefollowing privileges:

• The read access privilege specifics that users in auser group that have this privilege for aparticular resource can view only the windows that the resource comprises but cannotmodifv the parameters in the windows. The read access privilege limits access to windowsto read operations. Buttons such as Insert, Delete, Update, and Reset do not display.

• The update access privilege specifics that users in auser group that have this privilege for aparticular resource can view and change the parameters in the windows that the resourcecomprises. Users with update privileges can perform operations such as Insert, Delete.Update, and Reset as well as executive functions that can start or stop aprocess or servicefrom the Cisco Unified Communications Manager Administration and Cisco UnifiedCommunications Manager Serviceability windows.

• Roles and user groups provide multiple levels ofsecurity to Cisco Unified CommunicationsManager Administration and to other applications. The system groups the resources that areavailable to Cisco Unified Communications ManagerAdministration and to otherapplications into roles. Each application comes with standard, predefined roles. Eachapplication defines ils own access privilege for Cisco Unified Communications ManagerAdministration.

• Class ofservice (CoS): Defines the features that a user can use. For example. CoS controlsuser accessto licensed features such as the Cisco Unity Inbox. Whena CoS includes accesslo a feature that requires an individual license, users can be assigned to groups ofusers ofthe CoS only ifenough licenses are available. CoS also defines how users interact withCisco Unity Connection. For example, a CoS specifics the maximum length ofusermessages and greetings, and whether users can choose to be listed indirectory assistance.

• Templates: Three typesof templates exist:

— Usertemplates define standard useroperation and settings.

— Call Handler templates define operational modes.

Contacttemplates definestandardcontactsettings.

• Contacts: A system contact docsnothaveaccess to anyCiscoUnity Connection featuressuchas voice messaging. A system contact may represent a person in thecompany who hasa voice-mail account on another voice messaging system. A system contact might alsorepresent a customer or vendor who does notneed a voice mailbox, butwho frequentlycommunicates with Cisco Unity Connection users.

• Distribution Lists: Used to send voice messages to multiple users. The users that aremembers of a system distribution list typically areuserswho needthesame information ona regular basis, such asemployees ina department or members of a team. The class ofsen ice that is associated with each user account dictates whether users can send messagesto s\ stem distribution lists in Cisco Unity Connection.

• Call Management: Definesdifferent call handlersfor call routingandmessagehandling.

— Call handlers answer calls, play prompts to callers, provide callers with informationand options, route calls, and take messages.

— Directory handlersprovidedirectory assistance that callerscan use to reach CiscoUnity Connection users. Whena caller searches for a usemameor part of a name, adirectory call handler looksup the extension in the directory and routes the call.

— Interview call handlers collect information from callers by playing a series ofquestions that have beenrecorded. The answersarc recordedand sent to a voice-mail user. For example, administrators mightuse an interview handler to takesalesorders or to gather information for a product support line.

• Message Storage: Quotas can be specified to help control the size of user voice mailboxes.

• Networking: Whena messaging systemrequiresmore than one Cisco UnityConnectionsvstem, the servers can be networked together such that they replicate directory informationamong all the systems on the Cisco Unity Connection digital network or via Voice Profilefor Internet Mail (VPIM).

• Dial Plan: Dial plan flexibility is supported by using partitions and search spaces, withwhich administrators can segment the Cisco Unity Connection directory for both dialingand addressing. For example, partitions and search spaces can be configured to allow foroverlapping extensions.

System Settings allow configuration of global configuration parameters, for example:

• Licenses: Each license file is registered to the MAC address ofthe network interface card(NIC) on the Cisco Unity Connection server. The license file for one server cannot be usedon a second server (for example, because administrators want lo replace the Cisco UnityConnection server).

i 2010 Cisco Systems. Inc. Overview of Administrator and End-User Interfaces

Holiday Schedules: Cisco Unity Connection has three predefined schedules: All Hours.Weekdays, and Voice Recognition Update Schedule. Administrators can modify but notdelete the predefined schedules.

External Services: When users belong to a CoS that has access tothe Cisco UnityPersonal Call Transfer Rules feature, administrators can configure Cisco Unity Connectiontoaccess Microsoft F.xchange calendar information for a user, and toenable users to importtheir Microsoft Lxchange contacts. This allows users lo create Cisco Unity Personal CallTransfer Rules thatare based on their Microsoft Hxchange calendar andcontacts.IfCisco Unified MeetingPlace is installed inthe network ofthe company, administratorscan integrate the application as anexternal service so that users can review upcomingmeetings and joinactive meetings while onthe phone or while using the Cisco PersonalCommunications Assistant (Cisco PCA).

Lightweight Directory Access Protocol (LDAP): Ifadministrators are using a supportedLDAP-compliant directory as thecorporate directory. LDAP canbe integrated with CiscoUnitv Connection.

— Create Cisco Unitv Connection users by importing them from the LDAP directory

— Configure Cisco Unitv Connection to periodically resynchronize users with theLDAP directory

Simple Mail Transfer Protocol (SMTP): Cisco Unity Connection can notify a useraboutnew messages by callinga phoneor pager.Additionally, administrators can set up CiscoUnitv Connection to send message notifications via email.

SMPP: With the servicesand information lhat is provided by a wireless carrier, mobilemessaging sen ice provider or similar company. Cisco Unity Connection can use the ShortMessage Peer-to-Peer (SMPP) protocol to send message notifications in theshortmessageservice (SMS) format to cell phones and other SMS-compatibledevices when users receivenew messages, SMS is a "storeand forward service." whichmeansthat messages are notsent directly to the device used by the message recipient. Instead, an application like CiscoUnity Connection- known as an Internal Short Message Fntily (FSMF)—submits amessage to the SMSCenter(SMSC). The SMSCthen forwards the message to the device.

Telephony Integrations: Identifies the phonesystemswith which Cisco Unity Connectionintegrates. In Cisco Unilv Connection Administration, a phone system hasoneor more portgroups. Voice messaging portsare addedto the port group forconnectivity to. forexample,a Cisco Unified Communications Manager.

Tools: Cisco Unitv Connection provides different tools for easy maintenance andintegration tasks, for example:

— 1he Bulk Administration Tool allows administrators to create, update, and deletemultiple user accounts or systemcontactsal the same lime by importing informationthat is contained in a comma-separated value (CSV) file. In addition, it allowsadministrators to export information about users or system contacts from CiscoUnitv Connection to a CSV file.

— The Task Managementmenu lists various system maintenance and troubleshootingtasks lhat Cisco Unity Connection automatically runs on a regular schedule.

This figure describes how to configure end users in Cisco Unified Communications Manager toenable the end-user website access.

End users are either synchronized from EDAP or locally created. In both ways, users can beadded to agroup, which contains one or more roles. Cisco Unified Communications Managerhas acouple ofpreconllgured standard groups. Eor default end-user access, the end user mustbe added tothe Standard CCM End Users group. This group conlains two roles. Standard CCMEnd Users and Standard CCMUSER Administration. The Standard CCM End Users roleenables end users to log in to the /ccmuser web interface. Standard CCMUSER Administrationdefines which permissions the end user has.

Note The end user needs anassociated device ordevice profile toaccess his phone ordeviceprofile from the end-user website.

Customize User Website PermissionsThis figure describes how to customize end-user website permissions in Cisco UnifiedCommunications Manager. Go to User Management >Role and add anew role. Select theapplication Cisco Call Manager Administration. The GUI presented on the slide appears.

Customize User Website Permissions

Thedefault permissions ofStandard CCMUser Administration can bechanged or a new role can be added:

• Customized usergroups must contain theStandard CCM EndUsers role toenablelogin

• Effective access privileges from overlapping rolesor usergroupscan be configured inthe enterprise parameters:

The Role configuration page expands to display a list ofall the resources that are associated ^with the application. Privileges (read, update, or none) for each resource are selected from thislist. Access rights can be full access (both read and update check boxes are selected), read only(onlv the read check box is selected), and no access (both read and update check boxes arcunchecked).

When creating a new role, there are no privileges that are configured by default. Therefore, theadministrator needs to configure each option.

Youcansavetime when creating a newroleif youcopy anexisting rolethathas requirementsthat are close tothe requirements ofthe administrator and making the necessary edits.Otherwise, the administrator needs to configure privileges for each and every resource page.

Remember that standard roles cannot be deleted or modified. Custom roles can be created fromthe beginning or bycopying andthen modifying a standard role.

LDAP directories are specialized services that store user information ina database. Thedatabase is optimized for ahigh number ofreads and searches, and occasional writes andupdates. Directories typically store data that do not change olten, such as employeeinformation, userprivileges on thecorporate network, andso on.

The LDAP provides applications with a standard method for accessing and potentiallymodifv ing the information that isstored inthe directory. This capability enables companies tocentralize all user information ina single repository that isavailable to several applications,with a remarkable reduction inmaintenance coststhrough theeaseof adds, moves, andchanges.

Examples ofLDAP directories are Microsoft Active Directory, Netscape. iPlanct, and SunONE. Cisco Unified Communications Manager supportstwo types of integration:

• LDAP synchronization: Allows user provisioning where personal and organizational dataarc managed inan LDAP director)' and replicated tothe Cisco Unified CommunicationsManager configuration database.

• LDAP authentication: Allows user authentication against an LDAP directory. When usingLDAP authentication, passwords are stored andmanaged in LDAP. PINs are alwaysmaintained locally in Cisco Unified Communications Manager.

When LDAP synchronization is activated, some user data is nolonger controlled by CiscoUnified Communications Manager Administration webpages andmustbe changed in theLDAPdirectory itself, for example, the end-username fields.

Cisco Unitv Connection can transfer and screen incoming calls according to rules that end usersconfigure in the Cisco Unity Personal Call Transfer Rules web tool. Cisco Unity Connectionuses apersonal call transfer rule to transfer particular calls to an end user, according to calleridentity, time of day. and the end-user meeting schedule, or to transfer calls to voice mail or toanother phone number. End users can set rules to transfer calls to aphone number, aseries ofphone numbers, to amail-based paging address, or to send SMS messages.End users can build very simple personal call transfer rules—for example, to transfer acallfrom asingle phone number to voice mail—or create more complex rules by using thefollowing components:

• Personal contacts list: Cisco Unity Connection uses the personal contacts list torouteincoming calls, aswell as toplace outgoing calls.

Note End users can manage their personal contacts list in the Cisco Unity Assistant web tool.

• Caller groups: Callers can be organized into groups, in order to apply one rule to multiplecallers without having to recreate the rule multiple times. Caller groups can contain otherCisco Unity Connection users, system contacts, and personal contacts.

• Personal destinations: End users can create adirectory ofcontact phone numbers to whichCisco Unity Connection can route incoming calls.

Call Flows in Cisco UnifiedCommunications Manager andCisco Unified CommunicationsManager Express

OverviewIP telephony networks require seamless integration with the public switched telephone networkrem With multiple call paths available, network administrators need to have an m-d P1

understanding of call routing in order to control fhe path that ,s taken for aparticular call, andof course, to control call costs. This module covers call flows ,n C.scc-UnifiedCommunications Manager and Cisco Unified Communications Manager Express.

Understanding Call Flows andCall Legs

OverviewThis lesson provides an overview of call flows and call legs in Cisco Unified CommunicationsManager and Cisco Unified Communications Manager Express.

ObjectivesUpon completing this lesson, you will be able to describe the characteristics of calljlows andthe associated call legs in Cisco Unified Communications Manager and Cisco UnifiedCommunications Manager Express. This ability includes being able to meet these objectives:• Describe theCisco Unified Communications Manager callflows and call legs

• Describe the Cisco Unified Communications Manager Express call flows and call legs

Cisco Unified Communications Manager CallFlows and Call Legs

Phis topic describes the Cisco Unified Communications Manager call flows and call legs

• Before sending packets, IP phones will query the DNS serverto resolve the IP address of the Cisco UnifiedCommunications Manager.

11 DNS

and Respon

IP Phone

Cisco Unified Communications Manager can use either IP addresses or names to refer to otherIP devices in application settings. When names are used, they need to be resolved to IPaddresses by a Domain Name Svstem (DNS)server.

Both methods have some advantages:

• Using If addresses: The system does not depend on a DNS server. This situation preventsloss of sen ice when the DNS server cannot be reached. When a device initiates aconnection, the time that is required to establish fheconnection is shorterbecause no nameresolution is required (i.e.. a DNS lookup sent todie DNS server, and a DNS reply sentback from the server are not required). IJy eliminating the need for DNS, there is no dangeroferrors that are caused by incorrect configuration ofthe DNS. Troubleshooting issimplified because there isnoneed toverily proper name resolution.

• Using DNS: Management issimplified because logical names are simpler to process than32-bit addresses. IfIP addresses change, there is no need to modify the application settingsbecause thev can still use the same names. Only the DNS server configuration must bemodified inthis case. IP addresses ofCisco Unified Communications Manager servers canbetranslated toward IP phones because the IPphone configuration files donotinclude theoriginal server IP address (which should appear differently to the IPphone), but ratherinclude names. As long as these names are resolved to the correct (translated) address whenDNS requests have been sent outby IP phones. Network Address Translation (NAT) is nota problem.

In general, because ofthe additional point of failure lhat iscaused by configuration errors orbecause of unavailabilitv ofthe service, the recommendation is not lo use DNS with CiscoUnifiedCommunications Manager.


The figure illustrates acall between Cisco Unified Communications Manager-controlled IPphones where DNS is used.Before the IP phone can communicate with Cisco Unified Communicalions Manager, it mustresolve the name ofthe sener. The IP phone obtains the name ofthe server from theconfiguration file, which was downloaded from aTFTP server. Signaling messages can btexchanged between the IP phone and Cisco Unified Communications Manager only after thename ofthe sener hasbeen obtained.

No extra step (DNSlookup)

Higher availability

No dependency on the DNS server

The recommendation is to remove DNS reliance

Some implementations may require DNS. for example, integration withCisco Unified Presence

IP Phone AIP Phone B

When IPaddresses are used instead of DNS names for the Cisco Unified CommunicationsManager servers, ihe need for the extra step ofDNS resolution is eliminated. The signalingsession can bo set up immediate!} and calls can beprocessed even if the DNS service is notavailable, fherefbre. the recommendation is to remove DNS reliance.

Note Some Cisco Unified Communications Manager implementations may require a DNS server;for example, when integrating Cisco Unified Communications Manager with Cisco UnifiedPresence Server

In order to diange the default hehav ior ofusing DNS. perform the following steps for eachCisco Unified Communications Manager server inthe cluster:

1. In Cisco I'niiied Communications Manager Adminislralion, go lo System >Server.

2. Select the first (next) available server from the list ofCisco Unified CommunicationsManager servers.

3. Change the server name to ihe IP address ofthe server and save the changes.

By default, hostnamcs are also used in IP phone URLs. When DNS reliance hostnamcs are usedin these phones. UREs must also be replaced by IP addresses. Enterprise Parameters in CiscoUnified Communicalions Manager Administration are used lo configure the IP phone URLs.

Centralized Architecture PSTN Backup

Gateway supports PSTN access via SRST

Cisco Unified Communications Manager canbeconfigured with aPSTNbackup route via gateways

Call Forward Unregistered (CFUR)Ifthe primary IPWAN routefails, callsare rerouted overthesecondary PSTN route

In acentralized Cisco Unified Communications Manager deployment with multiple remotesites across the IP WAN. a centralized call processing model consists ofa centralized CiscoUnified Communications Manager cluster that provides services for many sites and uses the IPWAN to transport IP telephonv trafficbetween the sites.

When the IP WAN route fails, branch IP phones cannot reach the central Cisco UnifiedCommunications Manager. Therefore, remote IP phones are no longer registered with CiscoUnified Communications Manager and calls will no longer work.

Cisco Unified Communications Manager can be configured with aPSTN backup route viaCisco gatewavs. IfThe primary IP WAN route fails. Cisco Unified Communications Managerreroutes calls over the secondary PS'l Nroute. To route calls via the PSTN for unregistered IPphones. Cisco Unified Communications Manager can be configured using the Call ForwardUnregistered (CFUR) feature.

At the remote branch, ihe Cisco Unified Survivable Remote Site Telephony (SRST) feature,which is available in Cisco IOS gatewavs. provides call processing services to remote IPphones during an IP WAN outage. When the IP WAN is down, the IP phones at the remotebranch office can register to the branch SRS f router. The SRST router can process callsbetween registered IP phones and can send calls lo other sites through the PSTN. Whenimplementing the multisite WAN model with centralized call processing, consider thefollowing guidelines:

• Maximum of 1000 locations per Cisco Unified Communications Manager cluster.• Maximum of1100 H.323 dev ices (gateways, multipoint control units, trunks, and clients)

or 1100 Media Gatewav Control Protocol (MCiCP) gateways per Unified Cisco UnifiedCommunications Manager cluster.

Introducing Cisco Voice and Unifed Communications Administration (ICOMM) v8.0 ©2010 Cisco Systems, Inc.

Minimize delav between Cisco Unified Cisco Unified Communications Manager andremote locations toreduce voice cut-through delays.There is no limit to the number of IP phones at each individual remote branch. However,the capability that is provided by the SRST feature in the branch router limits the number ofIP phones controlled by each router. For example, on aCisco 3845 Integrated SeriesRouter amaximum of 720 Cisco IP phones arc supported during WAN outrage or tailovcrto SRST. The maximum number ofIP phones is platform-dependent.Use the location-based Call Admission Control (CAC) mechanism in Cisco UnifiedCommunications Manager to provide CAC into and out of remote branches. Cisco UnifiedCommunications Manager can support amaximum of 30,000 IP phones per cluster whenCisco Unified Communications Manager runs on the largest supported server. ResourceReservation Protocol (RSVP)-based CAC between locations can be used to supportnetworks that are partly and fully meshed, or networks that are fully meshed.

Cisco Unified SRST

Cisco Unified Communications Manager Express SRST

The following items must be considered when implementing PSTN backup:

• During an IP WAN failure. Cisco Unified Communicalions Manager reroutes calls oversecondary PSTN routes. Because the PS'l Nsupports only F. 164 numbering, the internaltelephony numbering scheme is not valid on the PSTN.

• One option is for the userto redial the full H. 164 number afteran IP WAN failure, ['hisoption is not the preferred solution.

• Abetter solution is for Cisco Unified Communications Manager to transparently modifythe dialed internal site codes to full F. 164 numbers before using the secondary PSTN route.Ibis procedure means that the userdoesnotneed to know the full H. 164 number andnoredial is necessary vvhen the primarv IP WAN fails.

• Cisco Ijfiiied Communications Manager support for various Cisco gateway signalingprotocols: 11.323 or Session Initiation Protocol (SIP) prov ides peer-lo-pcer communicationwith gateway s and other Cisco IInified Communications Manager clusters orCisco IinifiedCommunications Manager Express. Cisco IInified Communicalions Manager can controlCisco Voice Gatewavs and PSTN links using MGCP or SCCP.

• Because Cisco Unified Communications Manager is not reachable, no calls can originate orterminate on remote IP phones.

Abbreviated on-net calls between sites may need to be expandedto full E.164 numbers when rerouted over the PSTN.

Remote gateways are not required tocontrol IP phones.IPphones are still controlledby the localCisco UnifiedCommunications Manager cluster.

In adistributed Cisco Imilled Communications Manager architecture the PSTN backup pathselection can be based on the calling device. Cisco Unified Communications Manager can beconfigured to have different paths available to reach the same destination that may be selectedbased on the calling device,

Asecondary path can be used when the primarv IPWAN path isnot available as follows:

• Acall can be transparently rerouted over the PSTN during an IP WAN failure.

• Route pattern, route list, and route groups provide call routing flexibility.

Digit strings mav require modification. Abbreviated on-net calls between siles may need to beexpanded to full F.164 numbers when rerouted over the PSTN.

Note Remote gateways arenot required to control the branch IP phones because the local CiscoUnified Communications Manager cluster confrols theIP phones.

AAR Call FlowThis section describes the call flow for automated alternate routing (AAR).

AAR Call Flow

• The IP WANis fullyoperational.

• CAC blocks a call over the IP WAN.

• The call is automaticallyrerouted over the PSTN.- Alternatively. Call Forward NoBandwidth can be set.

To avoid oversubscribing WAN links with voice traffic and causing deterioration ofthe qualityofestablished calls. CAC is used to limit the number ofcalls between the sites. Centralizedcall-processing models can take advantage of AAR features. AAR allows Cisco UnifiedCommunications Manager to dynamically reroute acall over the PSTN ifthe call is deniedbecause of CAC as follows:

• AAR allows calls tobererouted through the PSTN by using an alternate number whenCisco Unified Communications Manager blocks a call due to insufficient locationbandwidth. With AAR. the caller does not need tohang up the phone and redial the calledpartv. Without AAR. the user would gel areorder tone and the IP phone would display the"Not enough bandwidth" message.

• AAR applies to centralized call-processing deployments. For instance, ifatelephone in acompany headquarters calls atelephone in branch Band the available bandwidth for theWAN link between the branches is insufficient (as computed by the mechanisms at thelocations). AAR can reroute the call through the PSTN. The audio path ofthe call would beIP-based from ihe calling phone to its local (headquarters) PSTN gateway, time-divisionmultiplexing (TDM)-based from that gateway through the PSTN to Ihc branch Bgateway,and IP-based from the branch B gateway to thedestination IPphone.

• AAR is transparent to users. It can be configured so that users dial only the on-net directorynumber. For example, all that is required to reach the destination is the four-digit number ofthe called phone. No additional user input is required to reach the destination through thealternate network, such as the PSTN.

In the preceding example, acall is placed from phone Ato phone B, but the locations-basedCAC denies the call due to insufficient bandwidth. Cisco Unified Communications Managernow automatically composes the required route pattern to reach phone Bvia the PSTN andsends the call off-net.

AAR CharacteristicsThissection describes the characteristics of AAR.

AAR Characteristics

- Provides a fallback mechanism for callsdenied byCallAdmission Control (CAC) and reroutes the calls over the PSTN.- Only works for locations-based CAC- Only works for calls placed to internal directory numbers

- AAR supportsthe following callscenarios:- Call originates from an IP phone within one location and

terminates at an IP phone within another location.- Incoming call through a gateway device within onelocation

terminates at an IP phone withinanother location.• AAR destination mask can be configured per device toreroute

calls to other phone numbers, such as cell phones.- Call Forward No Bandwidth (CFNB).- Forward to voice mail can be configured per device to

reroute callsto voice mail.

» AAR does not work with SRST.- Not activated by WAN failure

The characteristics of AAR are as follows:

• AAR provides amechanism for calls that are denied by Cisco Unified CommunicationsManager -based CAC or RSVP-enabled locations-based CAC by rerouting calls over thePSl'N in the event of CAC failure.

• AAR only works for calls placed to internal directory numbers. It does not apply to callsplaced to route patterns or feature patterns such as Mcct-Me or Call Park. However it doeswork for hunt pilots and computer telephony interface (CTI) ports. These entities can beconfigured with an AAR group and an AAR calling search space (CSS).

• The alternate number that is used for the PSTN call iscomposed ofthedialed number, aprefix that is configured per AAR source and destination group, and the external phonenumber mask of the called device.

• Alternatively, calls can be routed to voice mail or an AAR destination mask can beconfigured per device, which allows any number to be used for arerouted call. The numberlhat is specified at the AAR destination mask is also known as the Call Forward NoBandwidth (CKNB) destination.

Note AAR isa Cisco Unified Communications Manager fallback mechanism for calls thataredenied by locations-based CAC or RSVP-enabled locations-based CAC. It does not apply tocalls denied by external gateways due toexceeding theavailable oradministrativelypermitted number of channels or to calls that have been rejected on trunks (for example, ongatekeeper-controlled H.225 or intercluster trunks). If such calls fail for any reason, routelists and route groups provide additional fallback mechanisms.

Call Flows inCisco Unified Communications Manager andCisco Unified Communications Manager Express

AAR supports the following call scenarios:

• Acall originates from an IP phone within one location and terminates at an IP phone withinanother location.

• An incoming call through agateway device within one location terminates at an IP phonewithin another location.

AAR docs not work with SRST for the following reasons:

• AAR isnot activ ated by WAN failures, but only after CAC denies a call,

• If the AAR-composed number results in anumber with Ihe same area code as the gateway.typically the area code must not be dialed. In order to solve this problem, a translationpattern can be created that strips offthe area code before dialing the AAR-composednumber,

• Depending on the dial plan implementation and the type of calls (international, multiplecountries, and so on), additional modifications might be required.

• AAR does not support CTI route points as theorigin or destination of calls.

• AAR is not compatible with Cisco Extension Mobility for users who roam to differentsites.

• For off-net calls to the PSIN. telephony administrators may configure the access point tothe public network near the call origin ornear the call destination. Access to the PSTN nearthe call origin is referred toas headend hop-off (IIPTIO). Access to the PSTN near the calldestination is referred to as tail-end hop-off (TF.HO). When using THI10. it is important toconfigure the AAR CSS so lhat the local gateway is always used for calls being reroutedusing AAR. Othenvise calls will fail, because the call leg lo the (remote) PSIN gatewayagain runs into the same issue as the initial call. The call needs to go over the IP WAN."which typically means it goes out ofthe location ofthe originating phone. This route is notpossible because there is no bandwidth thai is lelt for the location, which is the reason whythe initial called resulted in a CAC failure.

Cisco Unified Communications Manager ExpressCall Flows and Call Legs

This topic describes the call flows and call legs in Cisco Unified Communications ManagerLxpress.

Cisco Unified CommunicationsManager Express Call Flow

• Cisco Unified Communications Manager Express uses dialpeers to establish logical connections, or call legs, tocomplete an end-to-end call.

«Adial peeris an addressable call endpoint.- POTS dial peersconnect to a traditional telephony

network.

- VoIP dial peers connect overa packet network.- IPphones are POTSdialpeers.

• Dial peers are defined foroutgoing destinations.• Defaultdial peer for incoming calls.

- Additional inbound dial peers maybe configured.

For calls to fiow correctly through the Cisco Unified Communications Manager Express, theadministrator must have a good understanding ofthe following:

• The locations ofthe telephony edgedevices

• The types ofconnections lhat need to be made between these devices• The telephone numbering scheme that is to be applied to the devices

Cisco Unified Communications Manager Express uses dial peers toestablish logicalconnections to complete an end-to-end call between devices. These logical connections arereferred to as call legs.

Fach dial peer is an addressable call endpoint. The type of dial peer is dependent on the actualconnection as follows:

• When using atraditional telephony connection, the plain old telephone service (POTS) dialpeermust be used.

• When connecting via an IP packet network, a VoIP dial peer is used. Additional dial peertvpes are available for connectivity to other network types. Other dial peer types includeVoice over Frame Relay (VoFR). Voice over ATM (VoATM), and Multimedia Mail overlP(MMolP).

© 2010 Cisco Systems, Inc.


Dial peers are defined for outgoing destinations. Multiple dial peers may exist in the sameCisco Unified Communications Manager Express and are matched based on destinationmatching criteria.

When an IP phone is configured in Cisco Unified Communicalions Manager Express, thesy stem automatically creates avirtual voice port thai represents the line (slate) on the phvsicalIP phone. Internally. a POTS dial peer isused for routing calls to the line extension number(virtual voice port), h may seem unusual that a POTS dial peer is used for an IP phone. Thereason is that an IP phone behaves in an identical manner to traditional analog telephonvdevices. However, instead ofaphysical voice port, avirtual voice port is used.Adefault dial peer is automatically available for matching incoming calls. Additional inbounddial peers may be configured when it is necessary to apply different characteristics to differentinbound calls.

Dial peers are used for both inbound and outbound call legs. Dial peers are used to identify callsource and destination endpoints and lo define the characteristics lhat are applied to each callleg in the call connection. Adial peer is associated with each call leg. Attributes that aredefined in adial peer and applied to ihe call leg include the codec, quality ofservice (QoS).voice activity detection (VAD). and fax rate.

It is important to remember lhat these terms are defined from the perspective of the CiscoUnified Communications Manager Express router as follows:

• An inbound call leg originates when an incoming call arrives at the Cisco UnifiedCommunicalions Manager Express router.

• An outbound call leg originates when an outgoing call is placed from the Cisco UnifiedCommunications Manager Express router.

Forinbound calls from a POTS interface thataredestined for the packet network, the routermatches aPOTS dial peer for the inbound call leg and avoice-network dial peer, such as VoIP.for the outbound call leg.

For inbound calls from the packet network, the router matches a VoIP dial peer to terminate theinbound VoIP call leg and aPOTS dial peer for the outbound call leg. Dial peers that define thecharacteristics ofapacket network connection are sometimes referred to as voice-network dialpeers.

Matching Inbound Dial Peers••hissection describes configurable parameters that are used for matching inbound dial peers.

Matching inbound Dial Peers

Configurable parameters used for matching inbounddial peers:

• incoming called number Definesthe called numberor DialedNumber Identification Service {DNIS) string

Applies to VoIP, POTS T1/E1 CAS, and ISDN dial peers• answer-address Defines the originating calling numberorAN)

string) to match the Incoming call leg loan inbound dial peer• port Attempts tomatch theconfigured dial-peer port

to the voice port that isassociated with the incoming callPOTS dial peers only

When determining how inbound dial peers are matched on aCisco Unified CommunicationsManager Fxpress router, ii is important to note whether the inbound call leg is matched to aPOTS orVoIP dial peer. Matching occurs in the following manner:

• Inbound POTS dial peers are associated with the incoming POTS call legs oftheoriginating router or gatewav.

• Inbound VoIP dial peers are associated with the incoming VoIP call legs ofthe terminatingrouter or gatewav.

When aCisco IOS router or gatewav receives acall setup request, it looks for adial-peer matchlorthe incoming call. This match isnota digit-by-digit match. Instead, (he router uses the fulldigit string that is receiv ed in the setup request for matching against the configured dial peers.Information elements lhat are sent in the call setup message and physical port are matchedagainst configurable dial-peer command attributes. These elements arcas follows:

• Called number Dialed Number Identification Service (DNIS): DNIS isthe call destinationdial string, and it isderived from the ISDN setup message orchannel associated sianalin*(CAS) DNIS.

• Calling number Automatic Number Identification (ANl): ANI is anumber string thatrepresents the origin, and it isderived from the ISDN setup message orchannel associatedsignaling (CAS) ANI. The AN! is also referred to as the calling line ID (CUD).

• Voice port: Voice port represents the POTS physical voice port.

The router orgatewav matches the call setup parameters inthe order thai is listed here:

I. The router orgatewav- attempts to match the called number ofthe call setup request withthe configured incoming called-number parameter ofeach dial peer.

3-24 Introducing Cisco Vorce and Unified Communications Adminislralion (ICOMM) v8 0 ©20IOCisco Systems. Inc.

2 If amatch is not found, the router or gateway attempts to match the calling number ofthecall setup request with the answer-address parameter ot each dial peer.

3 If amatch is not found, the router or gateway attempts to match the calling number of thecall setup request to the destination-pattern parameter ot each dial peer.

4 The voice port uses the voice port number that is associated with the incoming call setuprequest to match the inbound call leg to the configured dial-peer port parameter.

5. Ifmultiple peers have the same port that is configured, the router or gateway matches thefirst dial peer that isadded to the configuration.

6. Ifamatch is not found in the previous steps, the default is dial peer 0.

Because call setups always include the DNIS information, it is recommended to use theincoming called-numbcr command for inbound dial-peer matching. Configuring the incomingcalled-number command is useful for acompany that has acentral call center that providessupport for anumber of different products. Purchasers of each product get aunique toll-lreenumber lo call for support. All support calls are routed to the same trunk group destined for thecall center When acall conies in. the computer telephony system uses the DNIS to fiash theappropriate message on the computer screen ofthe agent to whom the call is routed. The agentwill then know how tocustomize the greeting when answering the call.The calling number ANI is used wilh the answer-address command when you want to matchcalls that are based on the originating calling number. For example, when acompany hasinternational customers who require foreign-language-speaking agents to answer the call, thecall can be routed to the appropriate agent based on the country ofcall origin.The calling number ANI is used with the destination-pattern command when the dial peersare set up for two-wav calling. In acorporate environment, the head office and the remote sitesmust be connected. As long as each site has aVoIP dial peer configured to point to each site,inbound calls from the remote sitewillmatch against thatdial peer.

Default Incoming VoIP Dial Peer

Ifthere is no dial peer match, use the default dial-peer 0.

Dial peer 0 default capabilities:• Any codec is supported• VAD is enabled

• DTMF relay is disabled

• Fax relay is disabled

• DSCPAF31 signaling

- DSCP EF media

• No RSVP support

Default dial peers are used for inbound matches only. They are not used tomatch outboundcalls thatdo nothave a dial peerconfigured.

fhe default dial peer is referred to as dial peer 0: it cannot be modified and is not displayedwith any slum commands.

Dial peer 0 lor inbound VoIP peers has die following settings:• Any codec is supported.

• QoS parameters lor signaling are differentiated services code point (DSCP) Al 31 and formedia. DSCP I.f for media.

• VAD is enabled.

• RSVP is not supported.

• The fax rate isset to voice andthe fax relay is disabled.

• There is no interactive voice response (IVR) application support.

The default dial peer 0 will fail to negotiate nondefaull capabilities orservices.

When the default dial peer is matched on a VoIP call, the call leg lhat is set up in the inbounddirection uses any supported codec for voice compression that is based on the requested codeccapability coming from the source router.

Introducing Cisco Voice and Unified Communications Administration (ICOMM) vS.O ©2010Cisco Systems, Inc

When adefault dial peer is matched, the voice path in one direction may have differentparameters than the voice path in the return direction. This difference in voice path parametersmav cause one side ofthe connection to report good quality voice while the other side reportspoor quality voice. For example, the outbound dial peer has VAD disabled, but the inbound callleg is matched against the default dial peer, which has VAD enabled. VAD would be on in onedirection and off in the return direction.

When the default dial peer is matched on an inbound POTS call leg, there is no default IVRapplication with the port. As aresult, the user gets adial tone and proceeds with dialed digits.

prefix 011

Outbound dial-peer matching is completed on adigit-by-digit basis. Therefore. Cisco UnifiedCommunications Manager F.xpress checks for dial-peer matches after receiving each digit andthen routes the call whena full match is made.

Cisco Unified Communications Manager Express matches outbound dial peers using thefollowing order:

• The Cisco Unified Communications Manager Express router uses Ihe dial peerdestination-pattern command to determine which dial peer will be used to route the call.

• The dial-peer configuration will then determine where to forward the call using one of thefollowing configuration commands:

— POTS dial peers usethe port command.

— Vol Pdial peers use the session targetcommand.

Ifmore than one dial peer matches the dial string, all ofthe matching dial peers are used toform arotary group. The router attempts to place the outbound call leg using all ofthe dialpeers in the rotary group until one issuccessful.Use the show dial plan number string command to determine which dial peer is matched to aspecific dialed siring. This command displays all matching dial peers in the order that they areused.

It may be necessary to manipulate digits in adial string before acall is passed to a remotetelephonv dev ice: for example, when calling PBXs with different capabilities to accept digits,or for PSTN and international calls. The Cisco Unified Communications Manager Fxpressrouter supports various strategies for configuring digit manipulation within dial peersdepending on the existing dial plan, the digits thai users are expected to dial, and thecapabilities ofthe PBX. These options, along with the destination pattern, determine the dialstring that the router forwards tothe telephony device.

Call Flows inCisco Unified Communications Manager and CiscoUnified Communications Manager Express

When Cisco Unified Communications Manager Fxpress matches the destination patlem in aPOTS dial peer, the matched (left-justified) digits are stripped and (he remaining digits areforwarded to the voice port. Dial peer configuration options allow for nondefault behavior sothat the destination digit string is presented in away that Ihe receiving telephony device-ex peets:

• Ihe no digit-strip command disables this automatic digit-stripping function so thatmatching digits are not stripped from the dialed string before it is passed to the telephonvinterface.

• fhe forward-digits command controls the number ofdigits thai are stripped before thedialed string is passed to the telephony interface. Afixed number ofdialed digits, or alldialed digits, can be forwarded regardless ofthe number ofdigits that explicitly match thedestination pattern.

• The prefix command can be used to add specific digits to the beginning of'ihe dialed stringbefore it is forwarded to the telephonv interface.

Influencing Outgoing Call BehaviorI'his section describes how to influence the behavior ofoutbound dial peers.

Influencing Outgoing Call Behavior

How to influence the dial peerusage {hunt selection):1 Longest match; ifmultiple matchesthen2 Explicit preference; if multiple matches then3 Random selection

Modify the hunt behavior:• dial-peer hunt command

• Eight variants and combinations can beselected- Longest match

- Explicit preference

- Random

- Least recent use

By default, the Cisco Unified Communications Manager Express searches for amatch. If thereare more matches for the destination pattern, the preference command is checked. Ifseveralmatched dial peers have the same preference, then the dial peers are selected randomly bydefault.

This hunting behavior can be influenced. To specify ahunt selection order for dial peers, usethe dial-peer hunt command in global configuration mode. Anumber from 0to 7selects apredefined hunting selection order as follows:

• 0: Default hunt order. Longest match inphone number, explicit preference, randomselection

• 1: Longest match inphone number, explicit preference, least recent use

• 2: Explicit preference, longest match in phone number, random selection• 3: Explicit preference, longest match inphone number, least recent use

• 4: Least recent use. longest match inphone number, explicit preference

• 5: Least recent use. explicit preference, longest match in phone number

• 6: Random selection

• 7: Least recent use.

"fhe least recent use option selects the destination pattern with the longest period oftime sinceit was last selected: that is. the longest idle time.

Lesson 2

Understanding theConfiguration ComponentsImpacting Call Flows in CiscoUnified Communications

Manager

OverviewImplementing atelephony class ofservice (CoS) means lhat not all users can access all callrouting table entries. The result is that for aspecific calling device orline, some destinationsare permitted while others are not. Olher devices or lines may be permitted to access differentdestinations. This lesson describes the configuration components that impact call flows inCiscoUnified Communications Manager.

ObjectivesUpon completing this lesson, you will be able to describe configuration components like CoS.Call Admission Control (CAC). route lists, route groups, and others that impact call flows inCisco Unified Communications Manager. This ability includes being able to meet theseobjectives:

• Describe Ihc concept of CoS

• Describe call routingin Cisco Unified Communications Manager

Cisco Unified Communications Manager CoSThis topic prov ides an overview ofthe concept ofclass ofservice (CoS).

Class of Service

Class ofservice (CoS) provides calling restrictions tocertain groups of users:

• Used to control telephony charges including:Block costly service numbers

Restrict international calls

* Used for special applications including:

Route calls with the same numberdifferently per user(different gateway per site for PSTN calls)

Route calls to thesame number differently pertime ofday

CoS isan important dial plan component. Sometimes called calling privileges, it isused toimplement control of access to the dial plan. It is oftendesirable that not all userscan accessallcall routing table entries, for example, for a particular calling device or line, some destinationsare permitted while others are not.

CoS provides callingrestrictions to certaingroupsof usersas follows:

• Ised tocontrol telephonv charges: For example. CoS isused to block costly servicenumbers or to restrict international calls.

• I'sed for special applications: Forexample, routing callswith thesame numberdifferently for each user (e.g.. use a different gateway perbranch site for public switchedtelephone network [PSTN] calls) or routing calls to the same number differently atdilTerenttimes ofthe dav.

The Long Distance class also allows long-distance PSTN callsand the International class also enables international PSTN calls.

Note The call privileges should besetaccordingly tothe current cost ofcalls. For example, ifnational costsarefree, you could build only two classes: long distance except mobile callsand infernational callsincluding mobile calls. ^^

Implementation ofCoS based on the different requirements ofeach originating device.Nontechnical issues such as the business needs of anorganization usually drive theserequirements.

For example, all employees may require full PSIN access including international dialing, whileother phones, such as the lobby phone, require emergency PSTN access only. Fhis scenarioshows a need for two distinct classes of service: one for the employees and another for ihelobby phone users.

Careful planning is required to listthe desired reachable destinations for each calling device.

The preceding tabic lists the Cisco Unified Communications Manager configuration elementsthat are used for calling privilege implementation along with their characteristics.The main features that are used toimplement CoS are partitions and calling search spaces(CSSs). Additional CoS features are available to allow various calling privilegeimplementations based on the individual needs ofthe customer.The Cisco Unified Communications Manager configuration elements that are used for callingprivileges are as follows:

• Partitions: Apartition is agroup ofdestination numbers with similar reachabilitycharacteristics (directory' numbers, route patterns, translation patterns, and so on).

• CSSs: ACSS isa list of(destination) partitions that are accessible from a particular(source) device.

• Time Schedules and Time Periods: Time schedules and time periods arc used toallowcertain partitions to be reachable only during acertain time ofthe day.

• Client Matter Codes (CMC): CMCs are used totrack calls to certain numbers for callaccounting and billing. Client Matter Codes force the user to enter acode to specify that thecall relates toaspecific client matter. The CMC isassigned lousers, such as customers,departments, or individuals. When configured, the user must enter the client code to tracktheir calls for accounting orbilling purposes. For example, totrack that the Salesdepartment has made acall, each sales person must enter the CMC assigned to Sales. TheCMC isused only for tracking purposes: it isnot used torestrict access. Ilowevcr, tomaintain accurate accounting and billing information, a call will be allowed only ifavalidCMC is entered.

Forced Authorization Codes (FAQ: These codes are used to restrict outgoing calls locertain numbers. Auser must enter an authorization code to reach the number. Forexample, acode must be entered to permit international dialing. IfFAC is combined withCMC. then both codes need to be entered.

Note Some devices, features, and applications do not support CMC and FAC. These applicationsor features (for example, call forwarding) need FAC- and CMC-free route patterns for calling.

Partition <None> and CSS <None>This section describes what happens to entities that do not have an assigned partition or CSS.

Partition <None> and CSS <None>

• By default, all entities that can have a partition reside inpartition <None>

- Directory numbers, route patterns, etc.• By default, all entities that can have a CSS are assigned CSS

<None>

- Calling entities such as IPphones, gateways, ortrunks• Entities that are in partition <None> are always accessible

- Regardless of whether or not the calling entity hasa CSS* Entities that have CSS <None> assigned can only access

destinations that are in partition <None>

- The recommendation is to have an empty <None>partition, andtherefore no calls can be made

By default, all entities that can be configured with apartition are in Ihe partition <None>. Allentities that can be configured with aCSS are assigned CSS <None> by default.Members ofpartition <None> (also called the null partition) are always accessible by sourcesofacall rouling request, regardless oftheCSS ofthat call routing source.

Entities that do not have a CSS assigned (for example CSS <None>) can only access callrouting targets thatare inpartition <Nonc>.

Note By default, no partitions and CSSs are assigned and all entities are associated with the nullpartition and CSS <None>. Therefore, by default, all calls are possible for all calling sourcesto all destinations.

CSS Partition Order RelevanceThis section describes situations where the order of partitions within the CSSs is important

CSS Partition Order Relevance

ACSS is an ordered list of partitions• All accessible entities ofthe call routing table areconsidered by

best match logic

Entities that are in a partition that is listed in the CSS of thecalling entity

Entities that do not have a partition assigned• Multiple identical entities can existinthe call routing tablebut must

be in different partitions

• If there isnosingle bestmatch, the call routing table entry whosepartition is listedfirst in the CSS of the calling device is used.

• Resulting route selection prioritiesBest match

Ifthere are many equally qualified matches, the order of thepartition in the CSS is the tie breaker.

ACSS is an ordered list ofpartitions. The partition that is listed first has ahigher priority than apartition listed later.

When Cisco Unified Communications Manager performs a call routing lookup, the best matchlogic cov ers all accessible entities: lhat is. all targets that reside in a partition thai is listed in theCSS ofthe calling phone and all targets that do not have a partition applied.

Multiple identical entities can exist in the call routing table, but they must be in differentpartitions. One exception to this rule is phone directory numbers. Iftwo or more devices sharethe same directory number within the same partition, this directory number iscalled a sharedline.

Ifno single best match is found, the call routing table entry whose partition islisted first intheCSS ofthe calling dev ice isused. In summary, the entry of the call routing table isselectedbased on ihe following order:

1. Best match is searched.

2. Ifmany equally qualified matches exist (no single best match), the order ofthe partition inthe CSS ofthe calling device is the tiebreaker: for example. Ihe match found in the earlierlisted partition.

In the example, aphone has aCSS thai contains two partitions, Chicago and San Jose.Destination directory numbers are assigned tothe partitions asfollows:

• Directory number 3001 (phone 2-1) is assigned tothe Chicago partition.

• Directory number 3001 (phone I-l) isassigned to the San Jose partition.

When the user places a call, thefollowing procedure applies:

• The user dials 3001.

• Cisco Unified Communications Manager uses the number 3001 and performs a call routinglookup through the partitions (Chicago and San Jose) listed in the CSS ofthe calling phone.

• Cisco Unified Communications Manager finds an equal (full) match for two entries: phone1-1 andphone 2-1 (San JoseandChicago).

• The Chicago partition is listed first in the CSS. so the call issent toChicago directorynumber 3001 (phone 2-1). Call routing iscomplete and phone 2-1 rings.

Note If thepartitions were listed in reverse order, the call would besenttoSan Josedirectorynumber 3001 (phone 1-1).

Note Although route pattern 300X matches the dialed number and is listed in the first partition, it isnot used to route the call in this example. The first priority for the call routing decision is thebest match. The order of partitions within the CSS is important only when multiple bestmatches exist.

Cisco Unified Communications Manager CallRouting

fhis topic prov ides an overview ofcall routing in Cisco Unified Communications Manager.

Call Routing Types

Intrasite

Intersite

PSTN

Routing Component and Characteristics -Calls within a single site (on-net)

• Uses assigned directory number to route callsinternally

• Directory numbers usuallyhave a uniform lengthCalls between sites:

• On-net uses internal directory numbers

• Off-net uses route patterns to send calls to other sitesthrough PSTN gateway; ifabbreviated dialing is used,internal number has to be translated to PSTN numberfirst

Calls toPSTN (off-net)" ""• Uses route patterns to send cafls to PSTN

destinations

In Cisco Unified Communications Manager, telephone calls need lo be routed andinterconnected based on thedialed number, 'fhis process is like IP routing. Call routing isdestination-based routing.

Three major areas of call routing exist as shown in the figure:

• Intrasite routing covers call routing within a single site.

• Intersite routing coverscall routing between multiple sites, franslation paltern are used forcentralized call-processing deployment models and route patterns are used for distributedcall-processing deployment models.

• PS'fN rouling covers call routing between a site and the PS'fN.

Cisco Unified Communications Manager automatically routes calls lo internal destinationswithin the samecluster,because it is configured with the directory numbers of its associateddevices. This tvpe of configuration is comparable to directly connected networks at a router inIP routing.

An explicit route, called a route pattern, must be configured for external destinations such as (1)PS'fN destinations (including off-net intersite calls,whicheffectively are PSTN destinations asthey are addressed by their PSTN number): (2) other VoIP domains such as an Internettelephony service provider (I'fSP): or (3) another Cisco Unified Communications Managercluster. This route is equivalent to static routes in an IP router.

In summary, the call routing table of Cisco Unified Communications Manager is composed ofconnected devices, directory numbers of registered IP phones, and statically entered routepatterns that point to external destinations.

Sources of Call Routing RequestsThe table shows sources ofcall routing requests, that is. entities lhat require a call routing tablelookup.

Sources of Call Routing Reque;

IP Phones

Trunks

Gateways

Translation

Patterns

Voice-Mai

Ports

The number dialed by an IP phone is looked up in therouting table.

Acall request received through a trunk is looked up in therouting table.

A call request received from a gateway is looked up in fhecalf rouling table.

Aftera translation pattern is best matched (as a target of acall routing table lookup) the transformed number is lookedup again in the call routingtable. The entity that generatesthislookup is the translation pattern.A voice-mail system can be configured to allow callingother extensions or PSTN numbers {e.g., the mobile phoneof an employee}. In these cases the call routing request isreceived from the voice-mail port of Cisco UnifiedCommunications Manager.

When thinking of ihe sourceof a call routingrequest, the simplestexample is an IP phoneplacinga call. However, thereare other routingcomponents thai can require acall routingtabiclookup. In addition to phones, calls can be received through gateways or trunks from theoulside. But there are other entities that are sources of call routing requests, which are not thatobvious:

• Translation patterns: A translation pattern is like a route paltern. It includes a paltcm (theentry in the call routing table). If matched by the dialed number, another number (thetranslated numberthat is configured by the translation pattern)is looked up again in therouting table. A translation pattern therefore combines both roles in a single entity:

It is a call routing table target that is matched by a dialed number.

Then, the translation pattern causes a new. second lookup for the translated number.

• Voice-mail ports: When a call has been sent lo a voice-mail system, the voice-mail svstemcan request that the call be transferred to another directory number, lo a PS'fN destination,for example, the mobile phone of a user, or to an assistant. In all these scenarios, the voice-mail port is the entity that requests the call being routed by Cisco Unified CommunicationsManager.

Note The distinction between call routing sources and call routing targets is extremely importantwhen implementing features such as calling privileges, call classification, and others.

Cisco Unified Communications Manager Call Routing LogicWhena numberis dialed.Cisco Unified Communications Managerusesclosest-match logic toselect which pattern tomatch from among all the patterns in its call routing table.

Cisco Unified CommunicationsManager Call Routing Logic

Cisco UnifiedCommunicationsManager usesclosest-match logicto select the bestdestination pattern.

When multiplematching patternsare present, thebest pattern isselected based on:

- It matches thedialed string

• AND

- It matches the User C ,fewest strings dials1234other than thedialed string

User A .dials120O

UserB ,dials1212

121X

1234

1234

In practice, vvhen multiple potentially matching patterns arcpresent, thedestination pattern ischosen based on the following criteria:

• It matches the dialed string.

• Among all the potentially matchingpatterns, it matches the fewest stringsother than thedialed string.

• Forexample, consider thecasethat is shown in the figure, where thecall routing tableincludes the patterns 1XXX. 12XX. 121X, and 1234:

• When user A dials the string 1200, Cisco Unified Communications Manager compares itwith the patterns in its call routingtable. In this case, thereare two potentially matchingpatterns. 1XXX and 12XX. Bothof themmatch the dialedstring, but 1XXX matches atotal of 1000 strings (from 1000 to 1999) while I2XX matches only 100strings (from 1200to 1299). Therefore, 12XX is selected as the destination of this call.

• When user B dials the string 1212. there are three potentially matching patterns. 1XXX,12XX. and 121X. As mentioned above, 1XXX matches 1000 strings and 12XX matches100 strings. However. 121X matches only 10 strings. Therefore, 121X is selected as thedestination of this call.

• When user C dials the string 1234. there are three potentially matching patterns. 1XXX.I2XX. and 1234. As mentioned above. 1XXX matches 1000 strings and 12XX matches100 strings. However, 1234matches only a single string (the dialed string). Therefore.1234 is selected as the destination of this call.

Overlap sending and receiving

fhe table shows the supported addressing methods in Cisco Unified Communicalions Managerfor different devices.

In Session Initiation Protocol (SIP), en-bioc dialing can be used in two ways. In Ihe first wav.the whole dialed string is sent in a single SIP INVl'f I: message. The other way is to use theKeypad Markup Language (KPMI.). which allows digits to be sent one by one. SIP dial rulesare dial rules that are processed inside the SIP phone. Thus, an SIP phone can detect invalidnumbers and play a reorder lone without sending any signaling messages to Cisco UnifiedCommunications Manager. If dialed digits match an entry of an SIP dial rule, the dialed stringis sent in a single INVITE message to Cisco Unified Communications Manager. If CiscoUnified Communications Manager requires more digits. KPML can be used lo send Iheremaining digits from the SIP phone to Cisco Unified Communications Manager one by one.

Trunks and PS I N interfaces can be configured for overlap sending and receiving allowingdigits to be sent or received one by one over an ISDN PRI.

User Input on SCCP PhonesThis section describes how Cisco Unified Communications Manager handles user input onSkinny Client Control Protocol (SCCP) phones.

User Input on SCCP Phones

• SCCP phones report every input event to Cisco UnifiedCommunications Manager immediately (stimulus protocol)- On-hook, off-hook, each digit dialed, etc.

• Cisco Unified Communications Manager analyzes phoneinput digit by digit against the configured dial plan andresponds with feedback.- Dial tone, ring back, reorder tone, etc.

• No dial plan information resides at the IP phone

SCCP (off-hook)

• io'ay dial tones

(first dialed digit)

SCCP IP PhoneCisco Unified

Communications Manager

Using the SCCP. IP phones report every user input event to Cisco Unified CommunicationsManager immediate!*'. For instance, as soon as the user goes off-hook, asignaling message issent from the phone l'o the Cisco Unified Communications Manager server with which it isregistered. The phone can be considered to be aterminal, where the Cisco UnifiedCommunications Manager server configured dial plan makes all decisions resulting from theuser input.

As other user events are detected by the phone, they are relayed toCisco UnifiedCommunications Manager individually. Auser who goes off-hook and then dials 1000 wouldtrigger five individual signaling events from the phone (off-hook and four individual digits) toCisco Unified Communications Manager. All the resulting feedback that is provided to theuser such as screen messages, playing dial tone, secondary dial tone, ring back, reorder, and soon. are commands that are issued by Cisco Unified Communications Manager to the phone inresponse to thedial plan configuration.It is neither required nor possible to configure dial plan information on IP phones runningSCCP. All dial plan functionality is contained in the Cisco Unified Communications Managercluster, including the recognition ofdialing patterns as user input iscollected.Ifthe user dials apattern that is denied by Cisco Unified Communicalions Manager, the reordertone is plaved to the user as soon as lhat pattern becomes the best match in Cisco UnifiedCommunications Managers digit analysis. For instance, ifall calls to 91976 are denied, vvhenthe user dials 91976123456, the reorder tone would be sent to the user's phone as soon as theuser dials 91976.

Ifan endpoint is sending dialed digits one by one, Cisco Unified Communicalions Managerimmediately starts digit analv sis when it receives the first digit.

In fact, digit analv sis starts even before the first number id dialed. This step begins when aphone indicates an off-hook state to Cisco Unified Communications Manager. The CiscoUnified Communications Manager looks up a null string dialed number, which matches allavailable call routing tables at this point. Adialed null string can be used in atranslation patternto offer private line, automatic ringdown (PI .AR) functionality.

As each additional digit is received. Cisco Unified Communications Manager can reduce thelist ofpotential matches (for example, the entries ofthe call routing tables lhat match the digitsreceived so far). Once a single entry ismatched (like the directory number 100I in theexample) the current match is used and the call issent to the corresponding device.

Note Cisco Unified Communications Manager does not always receive dialed digits one by one.SCCP phones always send digit by digit SIP phones can use en-bloc dialing tosend thewhole dialed string atonce or KPML tosend digit by digit. If digits are received en-bloc, thewhole received dial string is checked against thecall routing table at one time

In countries whose national numbering plan is not easily defined with static route patterns,Cisco Unified Communications Manager can be configured for overlap sending and overlapreceiving. Overlap sending means that Cisco Unified Communications Manager keepscollecting digits as they are dialed by the end users, and passes them on to the PS'fN as they aredialed. To enable overlap sending, check the Allow Overlap Sending check box on the RoutePattern configuration page. I'hc route paltern needs only toinclude the PSIN access code (forexample. "9" in North America or "0"inmany European countries).

Cisco strongly recommends using the complete route pattern, route list, and route groupconstruct because it prov ides the greatest flexibility for call rouling, digit manipulation, routeredundancy, and future dial plan growth.

1he1ocal Route Group feature helps reduce the complexity and maintenance efforts ofprovisioning in a centralized Cisco Unified Communications Manager deployment that usesmany locations with their own gatewavs.

The lundamental breakthrough in the Local Route Group feature comprises decoupling thelocation ofa PSTN1 gatewav from the route patterns that are used toaccess the gateway.

Cisco Unified Communications Manager supports aspecial Local Route Group that can bebound to aprovisioned route group differently based on the Local Roule Group device poolsetting ofthe originating dev ice.

Devices,such as IP phones from different locations, can therefore use identical route lists androute patterns, but Cisco Unified Communications Manager selects the correct gatewavs fortheir local end via the device pool.

The reserved name. Standard Local Route Group, identifies a local route group in configurationwindows. Ihe binding ofa provisioned local route group to ihc local route group occursdvnamicallv during call setup.

The information in the dev ice pool, towhich the originating device (such as a phone or trunk)belongs, prov idesthe basis for this binding.

With local route group mapping. Cisco IInified Communications Manager can treat gatewaysmore like a sen ice:

• Customers benefit because efforts related lo provisioning andmaintaining route plans arereduced as a result of this solution.

. For an implementation that comprises Nsites, in simple local routing cases, configurationof \ route patterns and \ route lists reduces to configuration of otic route pattern and oneroute list.

. Simple local routing comprises cases in which each site needs lo route off-net calls to itslocal gateways.

• Prov isioning of roule patterns and route lists can be reduced from the need to configure A'route patterns and Sroute lists to aconfiguration where only one route pattern and oneroute list are needed.

For this case it can be further assumed that all phones that reside at aparticular site belong to asingle CSS which is unique to that site. For example, phones at the Boulder site belong to theCSS called CSS-Bldr and so on.

Hunt Group Overview

Mam businesses have arequirement for amethod lo make many lines work together under asingle called number, such as ahelpdesk. Ahunt group is agroup of telephone lines that arcassociated with a common number.

Hunt Group Overview

• IPphones can be configured as hunt group members.• Calls toa single hunt pilot number aredistributed tohunt group members.

Use' dials

1-800-123-4567

Many businesses ha\ e sales orsenice support departments that work as groups to processinbound calls from customers. These businesses typically need several phone lines and amethod tomake the lines work together. Ifone representative isbusy ornot available, the callwill rotate lo othermembers ofthe group until il is answered or forwarded to an auto-attendantor voice mail.

Hunt groups are the mechanisms that help these businesses manage inbound calls. Ahunt groupis a group of telephone lines that are associated with a common number. When a callcomes intothe number associated with the hunt group, the call cycles through the group of lines until anavailable line is found, fhis process is known as hunting.

Cisco Unified Communications Manager call hunting implementation comprises the followingcomponents:

• Directory numbersor voice-mail ports areassigned to line groups.

• Line groups are assigned to hunt lists. Ahunt list can have one ormore line groups, fheline group hunt options and distribution algorithms can bespecified inorder todefine howcall hunting should be performed for the members ofa line group.

3-60 Introducing Cisco Voice and Unified Communications Administration (ICOMM) v8.0 >2010 Cisco Systems, Inc

• Hunt listsarc assigned to huntpilots. A hunt list is an ordered listof linegroups.

• Hunt pilots are the numbers that have been dialed to invoke a hunting process. Ahunt pilotcan becalled directly (for example, to provide a certain service to customers). A call canalsobe forwarded to the huntpilot from an IP phone that received a calland is configuredto forward calls to the hunt pilot to provide call coverage.

While hunting, the forwarding configuration of linegroup members is notused. Ifthe huntingalgorithm is ringing a phone and the call isnotanswered, theCall Forward No Answer (CFNA)setting of thatphone is ignored andthehunting algorithm goeson to the next linegroupmember.

Hunt Pilots

3-62

Hunt pilots are the numbers that havebeen dialedto invoke a huntingprocess.

Hunt Pilots

Hunt pilots are configured with a hunt pilot number:• The number that needs to be called to start a hunting process

* Perform digit manipulation

• Point directly to a hunt list

* Specify the maximum hunt timer

• Specify final forwarding settings (on hunt exhaustion)

A hunt pilot can be called directly (for example, to provide a certain service to customers). Acall can also be forwarded to the hunt pilot from an IP phone lhat received a call and isconfigured to forward calls to the hunt pilot to provide call coverage.

Hunt pilots arc dial patterns in the call routing table like route patterns and directory numbers.The hunt pilot points direct!} to a hunt list. Hunt lists point to line groups, which finally pointto endpoints.

At the hunt list, digit manipulation can be configured in order to transform the calling andcalled number before the call is passed on to line group members. Calls can be redirected to afinal destination when the hunting fails because of one or both ofthe following reasons:

• Al! bunting options have been exhausted and the call still is not answered.

• A maximum hunt timer lhat is configured at the hunt list has expired.

fhis call redirection is configured in the Hunt Forward Settings section ofthe hunt pilotconfiguration page, and the destination fortius redirect can be either ofthe following options:

• A specific destination that is configured global!) al ihe hunt pilot.

• A personal preference that is configured at the phone line of (he originally called numberwhen hunting on behalf of that number fails. The personal preference is configured usingthe Call Forward No Coverage (CFNC) settings at the phone line.

For example, the personal preferences option can be implemented by configuring a user's phoneso that the Forward No Answer field redirects the call lo a hunt pilot, in order to search forsomeone else who can answer the call. Ifthe call hunting fails, cither because all the huntingoptions were exhausted or because a time-out period expired, the call can be sent to adestination personalized for the person who was originally called.

Intrcducing Cisco Voice and Unified Communications Administration (ICOMM) v8.0 © 2010 Cisco Systems. Inc

• Setting the Forward No Coverage field within the person's Directory Number configurationpage will forward the call tothe voice-mail number. The call will be sent tothat person'svoice mailbox if hunting fails.

The following considerations applyto calls processed by hunt pilots:

• Call Pickup andGroup Call Pickup arc notsupported on calls thataredistributed by a huntpilot. A member ofthe linegroup cannot pickup a huntpilotcalloffered to anothermember in the line group, even if they belong to the same Call Pickup group.

• The huntpilot can distribute calls to any of its line groupmembers, regardless of callingprivilege implementation at the linegroup member. If linegroup members are configuredwith a partition, the huntpilot overcomes all partitions and CSS restrictions.

Call Admission Control

Multisite deployments are usually interconnected by an IP WAN where bandwidth is relativelycostly or limited. CAC is important in amultisite environment in order toavoid bandwidthoversubscription by too many voicecalls.

Call Admission Control

CAC limits the number of calls between certain partsofthe network in order to avoid bandwidthoversubscription:• Oversubscription results in delayed packets and packet

drops.

- All voice streams are affected (not only packets of a callthat exceeds the bandwidth limit)

- Results in quality degradation of all voice calls

• CAC avoids oversubscription problems by limiting thenumber of voice calls.

Whenoversubscription occurs in a VoIPnetwork, any packetsof any voice streamswill beaffected, not only Ihepacketsofthe particularcalls that exceedthe bandwidth limit.This factresults inpacket delays and packet drops of all voice callsandhence degrades the quality of allvoice calls. Therefore, in order to ensure good voice quality, CAC is used to limit the numberof voice calls and maintain bandwidth limits.

CAC limits the number of calls between certain parts ofthe network in order to avoidbandwidth oversubscription with too many voice calls. This goal cannot be achieved by qualityof service (QoS) as it only provides the means lo prioritize voice over data traffic.

CAC avoids oversubscription problems by limiting the number of voice calls in the network.

Location Characteristics

Ihis section describes Cisco Unified Communications Manager locations-based CAC.

Location Characteristics

• Each device has one location assigned.

• Calls are limited in and out of a location by permittingacertain bandwidth for calls,

Calls within a location are unlimited.

• Audio bandwidth is calculated by actual codec plus IPoverhead (assuming a 20-ms packetization period)

G.729

KB/s on Layer 3

80

24

Works within a Cisco Unified Communications Managercluster (including exit points)

- Trunks, gateways, etc. can be put into a location allowingsome control for calls leaving the cluster

Locations-based CAC is topology-unaware

Cisco Unified Communications Manager uses locations to implement CAC. Calls are limitedbv permitting a certain bandwidth for all calls coming into and going out of a location.

Cisco Unified Communications Manager calculates the actual audio codec bandwidth plus IPoverhead (assuming a packetization period of 20 ms). Therefore, each 0.711 call reduces thebandwidth thai is configured for a location by 80 kb/s while a (i.729 call reduces the availablebandwidth bv 24 kh/s.

Kach device has one location assigned, fhe assignment can be direct and via a device pool orvia a device pool alone. If both are used, the device configuration has a higher priority.

fhe configured bandwidth limit is independent ofthe destination location ofthe call. Unlike aregion configuration, where the maximum pemiitted codec is configured per pair of regions, ihebandwidth limit of a location applies to all interlocalion calls, regardless ofthe other location.

Locations provide CAC for calls within a cluster. However, because locations can also beconfigured for gatewavs and trunks, they do allow some control for calls leaving the CiscoUnified Communications Manager cluster.

I ocalions-based CAC in Cisco Unified Communications Manager is totally unaware ofthetopology ofthe network, ft is a purely logical assignment and does not reflect ihe actualtopology or the actual bandwidth available.

Note Calls within a location do not count toward the location bandwidth limit; they are unlimited.

The locations-based CAC algorithm considers only calls that go in or out of a location.


RegionsThis sectiondescribes Cisco Unified Communications Managerregions. Regions are used tocontrol the codec that is used for a call.

Regions

The codec that will be used depends on Cisco UnifiedCommunications Manager region configuration:• Each region is configuredwith the codec with the highest permitted

bandwidth requirements:

- Within the configured region

- Toward specific other regions (manually added)-••- Towardall other regions (that have not been manually added)

• Each region is assigned to a device pool.- Adevice pool isassigned to a device.

• Codec selection depends on the capabilities of the two devices:

- Best codec that is supported by both devices and does notexceed bandwidth requirements ofthe codec permitted in theregion configuration.

- ffdevices cannot agree on a codec, a transcoding device isinvoked.

The codec that will be used for a call depends on Cisco Unified Communications Managerregion configuration.

Lach device is assigned with a region via the device pool configuration. For each region, theadministrator can configure the codecwith the highestpcnnitledbandwidth requirement withina region, to other specifically listed regions, and to all other (not listed) regions.

When a call is placed between two devices, the codec is determined based on the regions ofthetwo devices and on the capabilities ofthe devices. The devices will use the best codec that issupported by both devicesand does not exceedthe bandwidth requirements ofthe codec that ispermitted for the regions that are involved in the call.

Ifthe two devices cannot agree on a codec (for instance, if region configuration allows G.729as the maximum codec but one device only supports G.711). a Iranscoder is invoked (ifavailable) to convert from G.711 to G.729.

In order lo conserve IP WAN bandwidth, a low-bandwidth codec should be used in the IP

WAN. For calls within a LAN environment, a high-bandwidth codec should be used foroptimal audio quality.

Note When designing where to use a type of codec, it is important to consider that a low-

bandwidth codec such as G.729 is designed for human speech. However, The G 729 codec

will not work well for other audio streams such as music on hold (MOH)

)2010 Cisco Systems, Inc. 3-69


Defining RegionsThis figure shows an example scenario for a typical codec configuration in Cisco UnifiedCommunications Manager.

Defining Regions

Typical region usage:* Use high-bandwidth codecs within a region.

• Use low-bandwidth codecs between regions.

Remember: Low-bandwidth codecs are designed forhuman speech and do not work well for other audiostreams such as fax or MOH.

The tabic in the figure shows a typical scenario for codec configuration in a Cisco UnifiedCommunications Manager multisite environment.

For calls within a site env ironment. a high-bandwidth codec should be used for optimal audioquality.

For calls between sites, a low-bandwidth codec should be used in order lo conserve IF WAN

bandwidth.

According to the preceding table. Cisco Unified Communications Manager regions areconfigured in the following wav;

• G.711 for calls between ihe headquarters IF phones

• G.711 for calls between branch l IF phones

• Ci.7l I lor calls between branch 2 IF phones

• G.729 for calls between the headquarters IP phones and any branch IP phones

• G.729 for calls between IP phones in different branches

As a result ofthe preceding configuration, all calls that use the IP WAN between the remotesites and the headquarters use G.729. Calls, local to one site, use G.711.

Cisco Unified Communications Manager supports the following CACfeatures

fJSv'^-'jnables ;oc3tiens

• Distributed call-processing deployments

H.323 gatekeeper C*C

In centralized call-processing deployments, locations and Resource Reservation Protocol(RSVP)-enabied locations can be used lo provide CAC. In the event where acall is notadmitted bv one ofthese two CAC methods due to bandwidth limitations, automated alternaterouting (AAR) can be used to reroute the call over the PSTN (off-net) instead of denying thecall. AAR provides asimilar service to PSTN backup, except that the trigger event is not acallfailure on the on-net path but no available bandwidth from the CAC point ofview.In distributed call-processing environmenLs, H.323 gatekeeper CAC can be used with 11.323trunks {gatekeeper-controlled intercluster trunks and 11.225 trunks). If the H.323 gatekeeperdoes not admit the call, standard backup functionality ofroute lists and route groups areapplied. For example, to route calls that have not been admitted by the gatekeeper to be sentover the trunk, one ormore PSTN gateways can be configured inanother (lower-priority) routegroup ofthe same route list. In this configuration, the gatekeeper-controlled trunk is preferredover the PSTN as long as calls are admitted; once CAC rejects acall, calls are sent over thePSTN.

Lesson 3

Understanding theConfiguration ComponentsImpacting Call Flows in CiscoUnified CommunicationsManager Express

OverviewImplementing atelephony class ofservice means that not all users can access all call routingtable entries. "Fhe result is thatfora specific calling device or line, some destinations arcpemiitted while others are not. Other devices or lines may be permitted to access differentdestinations. This lesson describes the concept ofcalling privileges and how they can beimplemented on Cisco Unified Communications Manager Express routers using class ofrestriction (COR).

ObjectivesUpon completing this lesson, you will be able to describe configuration components (COR. dialpeers, and so on) that impact call flows in Cisco Unified Communications Manager F.xpress.Thisability includes being able to meetthese objectives:

m Describe the concept of class of restriction

• Describe call routing in Cisco Unified Communications Manager Express

Cisco Unified Communications Manager ExpressCOR

Ihis topic describes Cisco Unified Communications Manager Express COR.

Class of Restrictioi

Cisco Unified Communications Manager Express uses theCisco IOS class ofrestriction (COR) feature to implementcalling privileges

COR defines the destinations a useris allowed to dial.

COR lists areassigned toephone-dns and dial peers:Incoming COR listfor calls arriving in Cisco UnifiedCommunications Manager Express

- Outgoing COR list for calls outbound from Cisco UnifiedCommunicationsManager Express

Calling priv ileges define thedestination to which a useris allowed to dial and connect. COR isaCisco gateway feature lhat enables class ofservice (CoS) orcalling privileges tobe assignedto phones.

Calling priv ileges areimplemented onCisco IOS gateways using COR lists. In Cisco UnifiedCommunications Manager Express. COR lists can be applied toany dial peer ordirectorynumber.

COR lists arc assigned loCisco Unified Communications Manager Express ephone-dn and dialpeers as follows:

• Incoming COR list is assigned forcalls arriving in Cisco Unified CommunicationsManager F.xpress

• Outgoing COR list is assigned for calls outbound from Cisco UnU'ial ComnuinicalionsManager Express

COR is highly dependent on properly configured call routing. Ifcalling privileges are not beingenforced effectively, it may have something todo wilh the way calls arebeing routed.

When deplov ing COR. it isoften necessar; tohave more granular dial peers. For example, itmav not be practical to use the 9Tdestination pattern asa"catchall" dial peer for outgoing callsto the public switched telephone network (PSIN). Creating new dial peers todistinguishamong intcmai. local, long distance, and international calls, and services such asemergency911 gives grealer control over which PSTN destinations are accessible.

COR BehaviorThis section describes the COR behavior when implementing calling privileges on CiscoUnified Communications Manager Express.

COR Behavior

Foreach call, the incoming COR list is matchedagainstthe outgoing COR list:• If the outgoing COR list is a subset of the incoming COR list,

the call is routed.

• If the outgoing COR list is not a subset of the incoming CORlist, the call is not routed.

international Call Penrsittert

The COR feature provides the ability to deny certain call attempts based on the incoming andoutgoing class ofrestriction lists provisioned on the dial peers.COR is used to specify which incoming dial peer can use which outgoing dial peer to make acall. Each dial peer can be provisioned wilh an incoming and an outgoing COR list.COR functionality provides the ability to deny certain call attempts based on the'incoming andoutgoing COR lists that are provisioned on the dial peers. This functionality provides flexibilityin network design, allows users to block calls (for example, calls to 900 numbers), and appliesdifferent restrictions tocall attempts from different originators.

Thelock and key analogy is useful here as follows:

• Outgoing COR listsare locked.

• Incoming COR lists contain the keys to open the locks.

The fundamental mechanism at the center ofthe COR functionality relies on the definition ofincoming and outgoing COR lists. Each COR list is defined to include anumber of members,which are simply tags previously configured as class ofrestriction members or tags.Multiple COR members or tags are defined, and COR lists are configured that contain theseCOR members or tags. Each COR list is then assigned to dial peers as an incoming or outgoinglist using the corlisl incoming orcorlist outgoing commands.When acall goes through Cisco Unified Communications Manager Express, an incoming dialpeer and an outgoing dial peer are selected based on the Cisco IOS dial-peer routing logic. IfCOR lists arc associated with the selected dial peers, the following additional check isperformed before extending the call:

Note Incommg and outgoing are terms that are used with respect to the voice ports For exampleif you try to make acalf from aphone that is connected to one of the Foreign ExchangeStation (FXS) ports of the router, it is an incoming call for the Cisco Unified CommunicalionsManager Express and voice port. Similarly, if acall is made to that FXS phone, then it is anoutgoing call.

Default COR BehaviorThis section describes the default COR behavior when implementing calling privileges onCisco Unified Communications ManagerExpress.

Default COR Behavior

When no corlist commands are applied to some dialpeers:

• If no incoming COR list is configured, thecall is alwaysrouted (master key).

• If nooutgoing COR list is configured, thecall is alwaysrouted.

!n*a'national Call Permitted

Outbound

POTS Call Leg

PSTN,,'

Ifno COR lisl statements are applied to the Cisco Unified Communications Manager Expressdial peers, the following properties apply:

• When no incoming corlist command isconfigured on adial peer, the default incomingCOR list is used. The default incoming COR list has the highest possible priority andtherefore allows this dial peer toaccess all other dial peers, regardless oftheir outgoingCOR list.

• When no outgoing corlist command isconfigured on adial peer, the default outgoing CORlist isused. The default outgoing COR list has the lowest possible priority and thereforeallows all other dial peers toaccess this dial peer, regardless oftheir incoming COR list.

In summary, the following call routing occurs when no COR list statements are applied to dialpeers:

• Ifno incoming COR list isconfigured, the call is always routed (like amaster key to alllocks).

• Ifnooutgoing COR list isconfigured, the call is always routed (no lock).

Cisco Unified Communications Manager ExpressCall Routing

This topic describes call rouling in Cisco Unified Communications Manager Express.

Call Routing Overview

By default Cisco Unified CommunicationsManager Egressselects the dialpeer wilh a destination pattern that matches the greatest number of dialeddigits

Dial peer 1 isselected because destination 91302 is Ihe longest match.Ifmorethanone outbound dial peer matchesthe dialstring, allmatching dialpeers are used to form a hunt group.

- Aloutbound dial peersinthe hunt group aretried until oneissuccessful.

DfelP**"2

When a call arrives inCisco Unified Communications Manager Express, theoutbound dial peerwith adestination pattern that matches the greatest number ofdialed digits isselected.When the call setup message contains all the digits necessary to route the call, Cisco UnifiedCommunications Manager Express searches for an outbound dial peer. The entire incoming dialstring is used to match outgoing dial peers.

In the preceding figure, dial peer 1is selected because destination 91302 is the longest match.Iftwo-stage dialing is required for the incoming call, the match isdone digit by digit. CiscoUnified Communications Manager Express enters digit collection mode (digits are collected in-band). Outbound dial peer matching isdone on adigit-by-digil basis. The Cisco UnifiedCommunications Manager Express checks for dial peer matches after receiving each digit andthen routes thecallvvhen the first match is made. Inthis case, dialpeer2 would beselectedbecause destination 9 matches.

Note If more thanone outbound dial peer matches thedial string, all matching dial peersare usedto form a hunt group. All outbound dial peersinthe hunt group are tried until one issuccessful.

When more than one outbound dial peer matches the dial string, all matching dial peers areused to fonn a hunt group. By default, all outbound dial peers in the hunt group are tried untilone is successful. Ihe Cisco Unified Communicalions Manager Express administrator canconfigure primarv and backup routes using the preference dial peer configuration option.

The dial peer preference indicates the preferred order ofthe dial peer within the hunt group asfollows:

• I'hc lowerthe number, the higher the preference

• Default 0

• Range (Ho It)

In the preceding figure, both dial peersare configured withthe samedestination address. Thisconfiguration means thatwhen a match occurs, both will fonn a hunt group.

Standard Cisco Unified Communications Manager Express dial-peer selection points to asingleinterface. To assign adial peer to multiple interfaces, perform the following:• Assign digital interfaces oranalog voice ports toaIrunk group.• Assign the trunk group to an outgoing dial peer as amember of one or more trunk groups.

fhe administrator has achoice ofcall hunting schemes to access ihe interfaces in the trunkgroup as follows:

• Ecast-used (default)

• Round-robin

• Eongest-idle

• Least-idle

• Sequential

• Random

When adial peer is amember of more than one trunk group, use the preference-num value toset the order in which the trunk groups will be used for the dial peer. Aprcferencc-num valueof I is the highest preference so that the trunk group is used first; avalue of 64 is the lowestpreference so that the trunk group isused last.Ifno value is entered for prcferencc-num. the software assigns the trunk group apreference of65. which causes that trunk group tobe selected after all other trunks are used.If two trunk groups have the same preference-num value, the trunk group that was configuredfirst is used before the other trunk group.

Basic Automatic Call DistributionCisco Unified Communications Manager Express supports an auto-attendant function and acallqueuing function Two Tool Command Language (Tel) scripts arc provided with Cisco UnifiedCommunications Manager Express software. The two functions together provide what isknown as the basic automatic call distribution (B-ACD) service.

Basic Automatic Call Distribution

• Basic automatic calldistribution (B-ACD) provides auto-attendant functionality to allow the callerto self-direct.

- Extension, voice mail, or ephone hunt group

• Provides call queuing functions if noagent in an ephone huntgroup is currently available:- Upto 10 auto-attendants- Maximum 10 ephone hunt groups

• Tools for collecting and obtaining callstatistics• Requires two built-in Cisco Systems Tel scripts in flash

memory:

- Auto-Attendant

-- Call queuing function

The built-in applications are app-b-acd-aa for the auto-attcndant feature and app-b-acd for thequeuing feature.

Configuring these applications is identical to configuring the external Tc! scripts, fheappropriate audio files must be uploaded into fiash memory.The first function ofthe B-ACD isthe aulo-attendant. 'fhe auto-attcndant function, called CiscoUnified Communications Manager AutoAllendant. The aulo-attendant can answer incomingcalls and present abasic menu ofup to four options. Commonly presented options includeenabling the caller to go directly to an extension by entering the extension number, go directlyto an operator by pressing 0. go to voice mail, orgo to an ephone hunt group.Ofthe four available options that are presented in the Cisco Unified Communications ManagerAutoAttendant menu, three can point to thepilot number of anephone hunt group.

Theautomated function isenabled through the configuration ofthe Cisco UnifiedCommunications Manager AutoAttendant Tel script.

Ifamember ofthe hunt group is unavailable, the second function ofthe B-ACD service, callqueuing, activates. The characteristics ofcall queuing are as follows:• Call queuing allows calls to be placed in aqueue in the order oftheir arrival.• Supports upto 10 auto-attendants and 10 ephone hunt groups.

SummaryThis topic summarizes the kev points thai were discussed in this lesson.

Summary

• To implement calling privileges, Cisco UnifiedCommunications Manager Express uses COR lists, whichare assigned lo dial peers and ephone-dns. When anoutgoing COR list isa subset ofthe incoming COR list a callwill be routed.

Using the trunk group feature, a single dial-peer destinationmatch can access multiple voice ports. Up to 64 trunk groupvoice ports can be accessed using the default least-usedhunt scheme.

Network Time ProtocolThis subtopic describes the NTP.

Network Time Protocol

- NTP is strongly recommended- All network devices keep the same time

• Publisher synchronizes to the master NTP clock source- External or internal to the corporate network

• Subscribers gettheir clock from thepublisher• IP phone gets the displayed time from the Cisco Unified

Communications Manager towhich itis registered

Subscribers

Internal NTP Clock

IP Phones

NTP can be enabled and configured during Cisco Unified Communications Manager _installation However, ifthe decision to use or not use external NTP servers was not consideredproperly during the initial configuration of Cisco Unified Communications Manager, >t shouldbe reconsidered beforedeploying endpoints.

Useof NTP is stronglyrecommended.

It is extremely important that all network devices have accurate time information because thesystem time of Cisco Unified Communications Manager is relevant in the following situations:• IP phones display date and time information. This information is obtained from Cisco

Unified Communications Manager.

• Call Detail Records (CDRs) and Call Management Records (CMRs), which are used forcall reporting, analysis, and billing, include date and time information.

• Alarms and events in log files, as well as trace information in trace files include timeinformation. Troubleshooting aproblem requires correlation ofinformation that is createdbv different system components (Cisco Unified Communications Manager. Cisco IOSgateway, and so on). This correlation is only possible when all devices in the network havethe same correct time information.

Some Cisco Unified Communications Manager features arc dale- or lime-based, and thereforerely on the correct date and time. These features include timc-of-day routing and certiticate-bascd securitv features.

In aCisco Unified Communications Manager cluster, only the publisher will send NTPrequests to the (external) NTP server(s); subscribers will synchronize their time with thepublisher. The configuration of an external NTP server is not required; ifno NTP server isconfigured—the publisher will rely on its own system time.

Network Time Protocol (Cont)

NTP usesa stratum todescribe how many NTP hops theclockreference is from an authoritative time source.

Stratum 1time server hasa radio oratomic clock directly attached.Stratum 2 time server receives itstime from a stratum 1time server,stratum 3 receives from stratum 2, and so on.

Lowest stratum number is preferred by clients when multiplesources are configured (stratum 1 is the best).

• The external NTP reference dock is preferred bythepublisher,and the internal NTP reference is the backup.

NTP is designed for synchronizing the clocks of computer systems over IP networks. It has ahierarchical organization bytheuse of clock strata.

Stratum 0is an extremely precise clock source, such as an atomic clock or radio clock. Astratum 1server isdirectly connected to astratum 0clock and can provide time information toother (stratum 2) devices. Stratum 2devices can serve stratum 3devices.Connectivity to stratum 0devices is limited. At best, astratum 1or 2connection may beavailable via the Internet.

The lowest stratum number has the highest priority and ispreferred by clients when multiplesources are configured (stratum 1is the best).

In the diagram, the external NTP reference clock is preferred by the publisher. The backup willbe the internal NTP reference.

Note It isrecommended that you use anexternal NTP server to ensure accurate system time onthe first node. Ensure that the external NTP server isstratum 9orhigher (highest internalNTP server is stratum 1). _^__^

Special Functions Used by Cisco IP PhonesThis subtopic describes special functions that arc used by Cisco IP phones in aCisco UnifiedCommunications Manager environment.

Special Functions Used by CiscoPhones

• Cisco Discovery Protocol: IP phones generate and listen toCisco Discovery Protocol messages.

• DHCP: IPphones can get their IP addresses via DHCP.

• Identification by MAC address: IPphones are identified by aunique device ID and not by their IP address.

• TFTP: IP phones are configured automatically bydownloading device-specific configuration files from a TFTPserver

Power over Ethernet (PoE): IP phones can be powered overthe Ethernet network cable.

PC Port: IP phones allow a PC to beconnected by sharing asingle connection to the switch.

Cisco IP phones integrate seamlessly into aCisco Unified Communications deployment. Inconjunction with other components ofthe overall solution. Cisco IP phones can provide thefollowing features:

• Cisco Discovery Protocol: Cisco IP phones generate Cisco Discovery Protocol messageslike almost all other Cisco network products. Cisco IP phones can also listen loCiscoDiscovery Protocol messages sent out by Cisco Catalyst switches. In this way. aCiscoCatalv st switch can indirectly configure the LAN configuration of the phoned including thevoice VFAN and class ofservice (CoS) settings for traffic that isreceived from an attachedPC. The Cisco Discovery Protocol messages that are sent by the IP phone are importantwhen using Cisco Unified Video Advantage, asolution in which IP phones can be used forvideo calls by interacting with video hardware and software thatis installed onthe PC.

• DHCP: Cisco IP phones can have sialic IP configuration, entered at the IP phone, or useDHCP lo obtain IPaddresses thatare assigned from a DHCP server.

• MAC address-based device identification: Cisco IP phones arc identified bv a device ID.which isbased on the MAC address ofthe IP phone. This identification allows the deviceto be moved between subnets and simplifies DHCP configuration, because no specific IPaddress is required foran individual phone.

• TFTP: Cisco IP phone configuration does not take place individually atthe phone, but iscentralized in Cisco Unified Communications Manager. Cisco Unified CommunicationsManager generates dev ice-specific configuration files andmakes them available fordownload at oneor more TETP servers. IPphones will learn the IP address ofthe TFTPserver via DHCP, and then load the appropriate configuration file automatically as part oftheir boot sequence.

Power over Ethernet (PoE): IP phones do not require wall power, but can obtain powerover the Fthernet from anv PoE compliant LAN switch, such as aC.sco Catalyst switchThis capability eliminates the need for extra power adapters and cabling on the user desk.PC port- IP phones allow PCs to be connected to aPC port at the phone and then share theuplink toward the switch. By using the voice VLAN feature of Cisco Catalyst switches andIP phones, the phone and the PC can be separated into different VEANs on asingle accessportat the LAN switch.

Cisco SCCP IP Phone Startup ProcessThis subtopic describes the steps in the standard startup process used by an IP phone to connectto the VoIP network.

Cisco SCCP IP Phone Startup Process

1 IPphone obtains power from theswitch.2 IP phone loads locally stored image.;, Switch provides VIAN information toIP phone using Cisco Discovery

Protocol.

4 Phone sends DHCP request, and receives IPinformation and TFTPserver address.

P IPphonegets configuration from TFTP server.IP phone registers with Cisco Unified Communications Manager:

- Cisco Unified Communications Manager sends softkey template to thephone using SCCP messages.

Depending on the specific network configuration, some or all ofthe following steps may occuron an individual IP phone:

Step 1 Obtaining power from the switch: The IP phone obtains power from the switch ifPoE is used. Alternatively, the IP phone can be powered by wall power or an inlinepower injector.

Step 2 Loading the stored phone image: The IP phone has nonvolatile flash memory inwhich the phone firmware image is stored. At startup, the phone runs abootstraploader that loads the phone image from fiash memory. Using this image, the phoneinitializes its software and hardware.

Step 3 Configuring Ihe VLAN: Ifthe IP phone is connected to aCisco Catalyst switch, theswitch uses Cisco Discovery Protocol to inform thephone whether or nottouse adedicated voice VI .AN for Ethernet frames carrying traffic toorfrom the IP phone(and leaving untagged frames for PC use). Ifthe voice VLAN feature is not enabledatthe switch and announced by Cisco Discovery' Protocol, ihc IP phone does notsend VLAN-taggcd Ethernet frames.

Step 4 Obtaining an IP address: Ifthe Cisco IP phone uses DHCP, the phone queries theDHCP server toobtain an IPaddress. DHCP also informs the IPphone about how toreach the TFIT server (DHCP option 150). IfDHCP isnot used, a static IP addressand TFTP server address must be assigned toeach IP phone locally. IftheDHCPserver does not respond. Ihe IP phone will make use ofthe last used configurationthat is stored in NVRAM.

© 2010 Cisco Systems, IncEndpoint and EndUserAdministration 4-11

Step 5 Requesting Ihe configuration file and the profile file: The TETP server hasconfiguration files and profile files. Aconfiguration file includes parameters forconnecting to Cisco Unified Communications Manager and information about whichimage load aphone should be running. Aprofile file contains various parametersand values for phone and network settings. Fhe IP phone first requests itsSnP<»wc>.cnfAml file from the TFTP server. If ihe TFTP server docs not respond,the IP phone (alls back to the last used configuration stored in NVRAM. Ifthe TFTPserver responds but the SEP</™c>.cnf.xm] file is not found on the server, the phonerequests the XMFDefault.cnf.xml (lie. From that file, the IP phone obtains ils list ofCisco Unified Communications Managers and then attempts lo autoregisterto theprimary server. Then the phone will attempt to download a Certificate TrustList(CTI.) file, which is only used ifcryptographic features are enabled in Cisco UnifiedCommunicalions Manager.

Step 6 Registering on Cisco Inified Communications Manager: The configuration fileincludes a prioritized list ofCisco Unified Communications Manager servers. Afterobtaining the file from the TETP server, the phone attempts to register with thehighest-priority Cisco Unified Communications Manager on the list. Ifthe phone isnot configured in Cisco Unified Communications Manager and autoregistration isenabled. Cisco Unified Communications Manager adds the device, and the phonecan then register. Once the phone has registered, the Cisco Unified CommunicationsManager sends the soflkey template lhat is configured for this IP phone tothe IPphoneusing SCCPmessages.


VLAN Discovery ProcessThis subtopic describes the IP phone VLAN discovery process.

VLAN Discovery Process

The Cisco Catalyst Switch isoptionally configured with VLANinformation

- Voice and data

IP phones useCisco Discovery Protocol to learn VLANconfiguration from a Cisco CatalystSwitch.Voice and data maybe configured to use separate VLANs.

- Provides security between voice and data VLANs- Simplifies QoS implementation using separate voice anddata

networks Learned Configuration:

Osco Router Catalyst Switch IP Phone

Voice and data may be configured to use separate VLANs. This type ofconfiguration canprovide security between voice and data VLANs as well as simplify quality of service (QoS)implementation.

The Cisco IP phone contains an integrated three-port 10/100 switch. The ports providededicated connections to the following devices:

• Port 0 is an internal 10/100 Ethernet interface that carries the IP phone traffic.

• Port 1 connects to a PC or other device.

• Port 2 connects to the access switch orolher network devices. Inline power can beobtainedat port 2.

The voice VLAN feature allows voice traffic from the attached IP phone and data traffic from adaisv-chained PC to be transmitted ondifferent VLANs. This capability provides fiexibility andsimplicity in IP address allocation and the prioritization ofvoice over data.

IP phones use Cisco Discovery Protocol to leam VLAN configuration from aCisco Catalystswitch. IfCisco Discovery Protocol isenabled onthe switch port, the switch instructs anattached phone lo treat the Eayer 2CoS priority value ofthe attached PC in one ofthefollowing ways (based on the extended priority lhat isconfigured atthe switch port):• Trusted: "fhe IP phone allows the PC to send IEEE 802.3 frames (with no CoS priority

value) as well as IEEE 802. Ip frames wilh any CoS priority value.

• Intrusted (default): The IP phone changes the CoS priority value to0 if802.1 p is used bythe PC.

• Configured CoS priority level: The IP phone sets an 802. Ip header with aCoS priorityvalue ofx ifthe PC uses 802.Ip with a di fferent CoS priority level than x,or ifthe PC didnot use 802.Ip at all. but sent 802.3 framesinstead.

IP Phone DHCP ConfigurationThis subtopic describes the IP phone DI 1CP configuration process.

IP Phone DHCP Configuration

• The IP phone initializes the IP slack and sends a DHCP request messageBroadcastto all devices in the (voice) VLAN

• The DHCP server response provides IPconfiguration parameters for theIPphone

IPaddress, subnet mask, defaultgateway, and TFTPserver address(option 150)

• The DHCP server may beonthelocal subnet orremote to IP phones.

Al power on. the IP phone initializes the IP stack and sends a DHCP request message. TheDHCP request message is sent as a broadcast toall devices in the voice VFAN. All devices inthe voice VLAN receiv e the request, but only the DHCP server responds.

In the diagram in the figure, the DIICPsener. TITP server,and Cisco UnifiedCommunications Manager server may be located in the same node orin separate nodes. Allthree servers will receive the broadcast DHCP request. TheTI'FPserver andCisco UnifiedCommunications Manager server will ignore the request. The DHCP server responds.

The DHCP server response prov ides IP configuration parameters for the IP phone as follows:• IP address, subnet mask

• Default gatewav

• TFTP server address (option 150)

The Cisco Unified Communications Manager DHCP server can be configured with multiplesubnets. In this case, the DHCP server may be on the local subnet or remote to some IP phones.When the IP phones arc in remote subnets, a DHCP relay must beenabled so that the DI ICPrequests that were sent out by the clients are forwarded to the DHCP server.

DHCP Server Feature Support OverviewThis subtopic describes DHCP server support in Cisco Unified Communications Manager

DHCP Server Feature Support Overview

• The DHCP server in CiscoUnified Communications Manageris designed to serve only IPphones.- Not designed toserve other network devices (PCs)

• Provides DHCP functionality for smaller deployments (up to1000 IP phones)

- Sufficient for IP phone purposes

• Only one DHCP server is recommended per Cisco UnifiedCommunications Manager cluster.

- DHCP server is a standalone server, no backup serverexists

• The DHCP service is normally provided on the publisher.

• Multiple subnets canbe configured onthe DHCP server.

The Cisco Unified Communications Manager DHCP server is designed to serve IP phones msmall deployments. In adeployment with no more than 1000 devices registering to the cluster.the DI ICP service may be coresident (two or more services or applications running on the sameserver) on the Cisco Unified Communicalions Manager server. For larger deployments, theDHCP server must be run on adedicated orstandalone server (with no other services running).The DHCP server provides DHCP functionality that is sufficient for IP phones, but it shouldnot be used for other network devices such as PCs.

The recommendation is that only one DHCP server exists per Cisco Unified CommunicationsManager cluster. DHCP isnormally provided onthe publisher.Fach DHCP server isa standalone server. Ifthe Cisco Unified Communications Manager thatisconfigured as the DHCP server fails, no backup server exists.

Each DHCP server must be configured fordifferent IP subnets.

'Fhe Cisco Unified Communications Manager administrator configures the DHCP servers andsubnets as follows:

• A maximum of one server for each node.

• Multiple subnetsmay exist on each server.

Different clusters can share one DHCP server, iftheCisco Unified Communications Managerclusters are not geographically separated. In the latter case, itmay need one DI ICP server perlocation. Ifthe DHCP server is shared, some Cisco Unified Communications Manager clustersmav have no DHCP servers.

>2010 Cisco Systems. Inc.Endpoint and End UserAdministration 4-15

Note The DHCP server of Cisco Unified Communications Manager must not be used withdeployments of more than 1000 registered devices. Even if there are fewer devices, theCPU load of the services must be watched closely. If high CPU load is experienced^ theDHCP service should be provided by other devices; for example, a dedicated DHCP serverswitch, router, and so on

Successful registration results in telephony configuration download lothe IP phone. The CiscoUnified Communications Manager server sends additional configuration elements to the IPphone during the final phases of the registration process including:

• Fine extension numbers and speed dials

• Soitkevs

• Other configuration elements

With autoregistration. the IP phone uses the XMLDefault.cnf.xml configuration file lo registerwith the Cisco Unified Communications Manager server. Once registered, a newSY:?<\fac_Address>.cr\1\\m\ configuration file is created.

In the diagram and following steps itis assumed that the SIP phone has obtained an IP addressand infomiation about how to reach a TFTP server. The following stepsexplain the SIPphonestartup process:

Step 1 The SIP phone boots and tries todownload a CTL file. The CTL file contains asetof certificates and isonly used when CiscoUnified Communications Managercluster security has been enabled.

Step 2 Ihe SIP phone requests its SEP<mac>.cnf file from the Cisco TFTP server. Ifa SIPphone is new. this file will not be found because the phone is not currentlyconfigured in the Cisco Unified Communications Manager database.

Step 3 The SIP phone downloads the default configuration file XMLDefault.cnf.xml fromtheTFTP server. Thisconfiguration file contains systemwide configurationparameters, including the location oftheCisco Unified Communicalions Manager ofthe SIP phone. For autoregistration towork for SIP. this file also contains aparameter called auto_registration_name. Ifthis parameter isblank, then the SIPphone will not attempt toautorcgister. Ifthis parameter isnot blank, the SIP phonewill attempt toautoregister if it finishes Ihc boot sequence and still does not haveany legitimate directory number lines that areconfigured.

Step 4 The SIP phone requests the .Loads file, ifone was specified inthe defaultconfiguration file, todetermine what image the phone should berunning. Ifthe.Loads file specifies an image thatisdifferent from the image contained intheSIPphone, the SIP phone attempts toobtain the new images from the Cisco TFTPserver. Ifthe image isdownloaded and verified successfully, theSIP phone willreboot to load the new image.

© 2010 Cisco Systems, Inc. Endpoint and End User Administration

Step 5 The SIP phones will download and use local dial plans iflocal dial plans areconfigured.

Step 6 Aconnection is established lo the Cisco Unified Communications Manager server.

Step 7 The IP phone will now register with the highest-priority Cisco UnifiedCommunications Manager server. The default SIP configuration file indicateswhether the SIP phone should conned using User Datagram Protocol (UDP) orICP.

Step 8 II the SIP phone does not have anv directory number lines provisioned, but ildoesha\ e the Cisco Unified Communications Manager IP address and port, the phonewill check the auto registration name parameter. Ifthe parameter contains a name,that name is used as the directory number line in the SIP Register message that issent to the SIPproxy. I 'pon receiving this message, theCisco UnifiedCommunications Manager should do the following:

• Identifv that the special autoregistration namehas been used.

• Create an entry in thedatabase for the new phone based on ihecurrentautoregistration settings.

• Generate the SFP</Hf/f>.cnf.xmI file for thenewphone.

• Acceptthe registration with the 200 OK response,

• Notify the phone to gel theconfiguration files again (Ifvent header in theSIPNOTIFY message).

• Fhe phone will automatically reset and reboot.

Step 9 The SIP phone will load the configured localization files.

Step 10 The SIP phone loads custom ringer files.

Fhe main differences between theSIPand SCCP startup processes areas follows:

• SEP</H(jc>.cnf.xml: The SIP phones get their entire configuration from the configurationfile. Therefore, theSFP<w<^>.cnFxml file is much larger for SIP than for SCCP.

• Dial plan file (optional): The SIP phones can download and use local dial plans.

• Softkey file: Ihe SIP phonesdownload their soflkeysets in this XML file.

Examples ofelements lhat are assigned through ihe device pool are the following:

• Cisco Unified Communications Manager (iroup (known as the Cisco Unified CM Group)• Regions

• DateAfime Group

Configuration elements can be optional ormandatory. Some mandatory elements have delimitsthat are predefined and administrators can make use of these defaults in basic scenarios. TheSecurity Profile isanexample of a mandatory element.

Asecurity profile must be applied toall phones that are configured in Cisco UnifiedCommunications Manager Administration. The administrator can make use ofexisting securityprofiles, which have securitv disabled.

Phone NTP ReferenceThis subtopic describes the phone Network Time Protocol (NTP) reference.

Phone NTP Reference

Configure a phone NTPreference to ensure thatSIP phones get date andtime synchronization fromthe NTP server.

Phone NTP references

will be selected in the

date/time group.

If none ofthe NTP servers

respond, the SIP phoneuses the date header inthe 200 OK response.

phone NTPRrfciwKn CtwTKMRirti™

e«* 10,2,250431 ^*m*^

Phone NTP references can beconfigured inCisco Unified Communications ManagerAdministration toensure that a Session Initiation Protocol (SIP) phone gets its date and timefrom an NTP server. Ifno NTP server isreachable, the SIP phone uses the date header inthe200 OK response to the register message for the date and time. Skinny Client Control Protocol(SCCP) phones obtain time information within SCCP messages.

After the phone NTP reference has been added to Cisco Unified Communications ManagerAdministration, itmust beadded toa date/time group. Priorities ofthephone NTP referencescan be configured in the date/time group.

fhe date/time group configuration is referenced from adevice pool, and the device pool isassigned to a device at the Device Configuration page.

Phone NTP reference information fields are as follows:

• IP Address: Enter theIPaddress ofthe NTP server thattheSIP phone should use to getitsdate and time.

• Description: Enter adescription for the phone NTP reference. Cisco UnifiedCommunications Manager Administration automatically propagates the information in theIPAddress field to the Description field, but il canbeedited.

>2010 Cisco Systems, Inc. Endpoint and End User Administration

Mode: From the drop-down list box. choose the mode for the phone NTP reference. Thevalues available areihefollowing:

— Directed Broadcast: Directed Broadcast is the default NTP mode. In this mode, thephone accesses dale/time information from any NTP server but gives the listed NTPsen ers (1st - primarv. 2nd - secondary) priority. For example, ifthe phoneconfiguration contains NIPservers where A= primary NTP server and B=secondary/backup NTP server, the phone uses the broadcast packets (derives thedate/time) from NTP server A. IfNTP server Ais not broadcasting, the phoneaccesses date/time information from NTP server B. If neither NTP server isbroadcasting, the phone accesses date/lime infomiation from any other NTP server.Ifno other NTP server is broadcasting, the phone will derive the date/time from theCisco Unified Communications Manager 200 OK response lo the register message.

- I nicast: In this mode, the phone will send an NTP query packet lo lhat particularNTP serv er, Ifthe phone does not receive a response, Ihe phone will accessdate/time information from anv other NTP server.

— Multicast: Ihis mode works in a similar way lo broadcast, except the NTPmessages from ihe sen erare not sent to all destinations (broadcast), but lo agroupofdestinations (multicast). This mode requires multicast routing configuration in theIP network.

— Anycast: This mode alsorequires multicast routing configuration in the IPnetwork,fhis mode works in asimilar way to unicast. Instead ofsending the NTP querypacket to a particular NTP server as a unicast. the phone will send to a multicastdestination. There is usually a primary server listening for the NTP traffic. Asecondarv serv erwill automatically receive the traffic vvhen the primarv server fails.The primary and secondary servers can be reachable anywhere in the multicastnetwork.

Note Cisco Unified Communications Manager cannot be configured asphone NTP references

A Cisco Unified Communications Manager Group specifies a prioritized listof upto threeCisco Unified Communications Managers. The first Cisco Unified Communications Managerin the list serves as the primary Cisco Unified Communications Manager for that group, and theother members ofthegroup serve assecondary and tertiary (backup) Cisco UnifiedCommunications Manager servers.

Each dev ice pool has one Cisco Unified Communicalions Manager Group that is assigned to it.When a device registers, ilattempts toconnect lothe primary (first) Cisco UnifiedCommunications Manager in the group that isassigned to its device pool. Ifthe primary CiscoUnified Communications Manager isnot available, the device tries toconnect tothe next CiscoUnified Communications Managerthat is listed in the group, and so on.

Cisco Unified Communications Manager Groups provide the following important features forthe Cisco Unified Communicalions System:

• Redundancy: This feature allows the administrator todesignate primary and backup CiscoUnified Communications Manager servers for each group.

• Call processing load balancing: 'Fhis feature allows the administrator todistribute thecontrol of devicesacrossmultiple Cisco Unified Communications Managerservers.

For most systems, there is a need for multiple groups. Asingle Cisco Unified CommunicationsManager can be assigned to multiple groups to achieve better load distribution and redundancy.

Locations ConfigurationFhis subtopic describes the Locations configuration.

Locations Configuration

• Add locations to implement call admission control ina centralizedcall-processing deployment,

• Regulate audio quality and video availability by limiting theamountof bandwidth that is available foraudio and video calls.

Use locations to implement Call Admission Control (CAC) in a centralized call-processingsystem. CAC enables the administrator to regulate audio quality and video availability bylimiting the amount ofbandwidth that is available for audio and video calls thai go in or out ofa location.

Each location is assigned a name. The location name will be assigned todevices such as IPphones. It is helpful ifthe names follow some meaningful structure such as "Branch 1" or"Central Site."

In a central i/edcall-processing system, a single Cisco Unified Communications Managercluster provides call processing for all locations on the IP telephony network. The CiscoUniiied Communications Manager cluster usually resides at the main (orcentral) location,along with other devices such as phones and gateways. The remote locations contain additionaldevices, but no Cisco UnifiedCommunications Manager. IP WAN links connect the remotelocations to the main location.

Note IfCAC is notused to limit the audioand video bandwidth on IPWAN links, an unlimitednumber of calls can be active on that link at the same time.This situationcan cause thequality ofall audio andvideo calls todegrade as thelink becomes oversubscribed.

Autoregistration

Ihis subtopic describes the Cisco Unified Communications Manager autoregistration featureforassigning extension numbers to new IPphones.

Autoregistration

• Supported by all Cisco IP phones.

* Existing endpoints are not affected.

• Automatically adds IP phones not found in database

Based on MAC addresses

* An autoregistration directory number range is configured.

Each IP phone added by autoregistration is assigned withthe next available directory number of the configuredrange.

• Cisco Unified Communications Manager BAT can be used tomake bulk changes after autoregistration.

* The Cisco Unified CommunicationsManager Auto-RegisterPhone Tool can be used to associate phones with specificdirectory numbers after autoregistration.

Autoregistration allowsCisco Unified Communications Manager to issueextension numbers tonew IP phones. This process is like the way in which the DHCPserver issues IP addresses.

When autoregistration isconfigured and enabled, a new IP phone boots and attempts to registerwith Cisco Unified Communications Manager for ihe first time, and then Cisco UnifiedCommunications Manager issues an extension numberfrom a configured range. AfterCiscoUnified Communications Manager issues theextension, it adds the phone to itsconfigurationdatabase with the used device ID (MAC address) and the assigned extension.

After the phone is added, theassigned extension usually must usually be modified because aspecific extension is intended to be usedfor a given phone. Therefore, autoregislralion onlyslightly simplifies registration whenadding many IP phones. The MAC addresses ofthe phonesare automatically added to the Cisco Unified Comniunications Manager configuration database.The extensions per phone must still be modified.

Some phone sellings, such as device pools, need to be globally changed from their defaultvalues. Use Cisco Unified Communicalions Manager BAT after phones have beenautoregistered.

for largedeployments, use the Cisco Unified Communications Manager Auto-Register PhoneTool, which allowsspecific extensions to be assigned lo individual phones basedon user input.

Autoregistration is supported by all IPphones and does not affect phones lhat are alreadyconfigured.

Cisco Unified Communications Manager BATThis subtopic describes the Cisco Unified Communicalions Manager BAT.

Cisco Unified CommunicationsManager BAT

• Cisco Unified Communicalions Manager BAT performs bulktransactions to the Cisco Unified Communications Manaqerdatabase.

• Fast efficient method to add, update, or delete a largenumber ofsimilar phones, users, or ports at thesametime.

• Export data (phones, users, gateways, and so on}Exported files can be modified and reimported.

• Integrated with the Cisco Unified Communications ManagerAdministration pages and available by default.

• Supports localization.

• Cisco Unified Communications Manager Auto-RegisterPhoneToo! also available from Bulk Administration menu butrequires additional products.

Ciseo Unified Communications Manager BAT allows for fast and efficient bulk update,addition, or deletion ofCisco Unified Communications Manager configuration databaserecords, including the capability toadd phone records.

Ihe Cisco Unified Communications Manager BAT' is integrated with the Cisco UnifiedCommunications Manager Administration pages and available by default.

features include import and export ofdata files lo and from the Cisco Unified CommunicationsManager configuration database as follows:

• Import data, such as phones, users, gateways, and others, are output to files. These filescontain the data fields thai are needed for configuration, such as IP phone parameters.

• Lxported files canbe modified andreimported.

When using Cisco Unified Communicalions Manager BAT to add phones, the administratormust specify the MAC addresses ofthe IP phones along with the respective directorv numbersintheBA'l files.

Note The MAC address isprinted in text and Universal Product Code (UPC) form onboth theshipping box ofthe IPphone and on the IPphone itself, which allows the use ofbarcodescanners rather than manually typing MAC addresses into BATfiles.

Alternatively, the administrator can use autoregistration first, so thai Cisco UnifiedCommunications Manager includes all phones with their MAC addresses and the directorynumbers that were assigned by autoregistration. fhe administrator can then modify ihedirectorv numbers in the exported tiles by replacing the directory numbers thai were assignedby autoregistration with those that are actually desired for the individual phones. These editedfiles can then be used bv Cisco IInified Communications Manager BAT' to update the phonerecords in the database.

Understanding TelephonyFeatures

OverviewCisco Extension Mobility allows users in CiscoUnified Communications Manager or CiscoUnified Communications Manager Express to usedifferent IPphones, regardless of theirlocation, with their own settings and personal directory number. Many businesses havedepartments thatwork as groups to handle inbound calls from customers. Thesebusinessestypically need several phone lines and a method tomake the lines work together so that if onerepresentative is busy ornotavailable, the call can beanswered byother members of the groupor forwarded to another number or voice mail, fhis can be done with call pickup groups, huntgroups, or shared lines. CiscoUnified Communications Manager and Cisco UnifiedCommunications Manager Express have a wide rangeof call coverage features to ensure thatincoming calls can beanswered, the line states of directory numbers can be monitored, andcalls between end users can be handled.

The Cisco Extension Mobility feature allows users to log in to any IP phone and have theirindividual user-specific phone configuration applied to the phone they are using. Users arereachable al their personal extension regardless of their location and the physical phone theyuse.

Cisco Extension Mobility is implemented as a phone service and traditionally works within aCisco Unified Communications Manager cluster. Cisco Extension Mobility Cross Cluster(EMCC) support was introduced with Cisco Unified Communications Manager version 8.0.

Cisco Extension Mobility allows users to log in to any phone and get their individual user-specific phone configuration applied to the phone that they arc using. Thus, users can bereached al their personal directory number, regardless ofthe location or physical phone.

The user-specific configuration is stored in device profiles. After successful login, the phone isreconfigured wilh user-specific parameters; other (device(-specific parameters remain thesame. If a user is associated with multiple device profiles, the user must select the deviceprofile to be used. If a user logs in wilh a user ID that is still logged in at another device, one ofihe following options can be configured:

• Allow multiple logins: When this method is configured, ihe user profile is applied to thephone where the user is logging in and the same configuration remains active at the devicewhere the user logged in before. The line numbers become shared lines as they are activeon multiple devices.

• Deny login: In this case, the users get an error message. Eogin is only successful after theuser logged out at the other dev ice where ihe user logged in before.

Cisco Extension Mobility Login ProcessThis subtopic describes the Cisco Extension Mobility feature login process,

Cisco Extension Mobility Login Process

User presses the services button onan IP phone and selects the CiscoExtension Mobility service

The user is authenticated by user IDand PIN

After successful authentication,Cisco Extension Mobility selects thedevice profile associated with theuser (prompts user to select ifmultiple associations exist)

The IP phone configuration isupdated with the configurationparameters from the device profile.

The IP phone resets and loads theupdated configuration. Cisco Unified

Communications

Manager Database

When a phone user wants to log in to a phone, the following sequence of events occurs:

• The user presses the Services button on the phone and selects the Cisco E.xlension Mobilitysen ice from the list of phone services available at the phone.

• The Cisco Extension Mobility service requires the user to log in by user ID and PIN. Theuser enters the required data.

• Ifthe entered user ID and PIN are correct. Cisco Extension Mobility selects the deviceprofile that is associated with the user.

• Cisco Unified Communications Manager updates the plione configuration with the settingsofthe selected dev ice profile. User-specific device-level parameters, lines, and other phonebuttons are updated with user-specific settings.

• 'fhe IP phone is reset and loads the updated configuration.

Users can now utilize the phone as if they were using their own phone al their home location:directorv' numbers, speed dials. Message Waiting Indicator (MWI).and other settings are allcorrect, regardless ofthe location and the IP phone that is being used.

Users can logout of Cisco Extension Mobility by pressing the Services button and choosingLogout in theCisco Extension Mobility service. If users donot logout. ihe system willautomaticallv log them out after the expiration ofthe maximum login time (ifthe appropriateService Parameter has been configured accordingly).

The user is also automaticallv logged out of a phonewhenthe user logs intoanotherphone andCisco Unified Communications Manager is configured for auto-logout on multiple logins.Another option is that ihe current userofthe phone logs oula previous user. Thecurrent usercan then log inand update the phone with their personal settings. After logout. Cisco UnifiedCommunications Manager reconfigures the phonewith eitherthe standard configuration oftheIP phone or another device profile.

Note Ifa user is associated with more than one device profile, all associated profiles aredisplayed andthe user must selectthedesired profile, Auser may be assigned multipleprofiles so that separate profiles are available ona per-site basis. This procedure iscommonwhen the traditional approach is usedto implement calling searchspaces (CSSs), CiscoExtension Mobility only updates the line configuration (including the line calling searchspace)butnotthe device calling searchspace. In orderto allow the selection ofa localgateway, a different (line) calling searchspace must be applied per site. In sucha scenario,the user selects a site-specificdevice profile that differsfromthe device profile that is usedat other sites in its line CSS. The line calling search space of such site-specific profiles givesaccess to routepatternsthat routepublic switched telephonenetwork (PSTN) callsto theappropriate (local) gateway.

Administrators can configure each IP phone lo support Cisco E.xlension Mobility by using thedefault dev ice profile. This procedure allows users who do not have a user device profile for aparticular IP phone to use Cisco Extension Mobility with that phone.

A device profile defines the attributes ol a particular device. A device profile includesinfomiation such as the phone template, user locale, subscribed services, and speed dials.

The dev ice profile is not associated with a physical phone. It includes all the properties of adev ice except those that arc explicitly lied lo the device, such as MAC address or directoryURE. When a dev iee profile has been loaded onto a device, the device adopts the attributes ofthat device profile.

When a user logs in to a phone that is configured for Cisco Extension Mobility and the user hasa user device profile that is configured for thai phone, ihc user device profile replaces theexisting configuration ofthe device. When a user logs out. the logout profile replaces the userdevice profile.

Call Coverage in Cisco Unified CommunicationsManager

This topic describes call coverage in Cisco Unified Communications Manager. Thediagrampresents different call forward options.

Call Forward Options

Users and administrators can define different call forward

options;

• Set on the directory number configuration pages.

• Call forward all can be set on the IP phone.

• Call forward permissions can be restricted with calling searchspaces.

TTie Cisco Unified Communications Manager supports different types of call forwarding:

• ('all Forward All (C'FA): CEA means that al! calls are forwarded unconditionally. CEAcan be configured by the phone user from either the user web page or at the phone itself. IfCEA is configured, the call is forwarded immediately without ringing the originally dialedphone. For CEA. a primary and a secondary CFA can be configured, which can be linkedtogether in a manner similar to a device and line calling search space. Eor all call forwardscenarios, the corresponding call forward calling search spaces are used; line and devicecalling search spaces are ignored. Therefore, ifthe system uses partitions, it isrecommended to always set call forward calling search spaces. If call forward callingsearch spaces are not used, forward operations are likely to fail.

• Call Forward Busy (CFIJ): CEB fonvards calls that are received while the IP phone is inuse with another call. CEB can be configured by the administrator in Cisco UnifiedCommunications Manager Administration or by the phone user from the user web page.The settings in this row of fields specify the forwarding treatment for internal calls to thisdirectory number ifthe directory number is busy and the busy trigger setting is reached.The call forward busy trigger determines how many active calls exist on a line before thecall forward busy setting gets activated. Cisco Unified Communications Manager allowsvou to define different call forward destinations based on whether the call is internal or

external.

) 2010 Cisco Systems. Inc. Enablement of End User Telephony and Mobility Features

• ("all Forward No Answer (CFNA): CFNA forwards calls ifthe call is not answeredwithin a specified amount of time. CFNA can be configured by the administrator in CiscoUnified Communications Manager Administration or by the phone user from the user webpage. The Cisco Unified Communications Manager allows you to define difierent callforward destinations based on whether the call is internal or external.

• Call Forward No Coverage (CF1NC): CENC forwards calls when a user forwards calls toa hunt pilot and the hunt pilot is temporary not available CENC also forwards a call if ilcannot be answered bv a member of a line group. In the Hunt Pilot configuration settings,use the Personal Preferences Destination fields to enable the CENC destination for the

original called number that forwarded the call to the hunt pilot. 'Fhe Cisco UnifiedCommunications Manager allows you to set different call forward settings for internal andexternal calls.

• Call Funvaru* un CTI Failure: fhis field applies only to computer telephony integration(CTI) route points and CTI ports. The settings in this row specify the forwarding treatmentfor external calls to this CI'l route point or CTI port ifthe CTI route point or CTI port fails.

• Call Forward Unregistered (CFUR): CEUR applies when no device with the configureddirectorv number has registered successfully to the Cisco Unified CommunicationsManager: for example, when a device al a remote office looses the WAN connectivity.

• No Answer Ring Duration: Used in conjunction with CFNA destination, this field sets thetimer for how long the phone will ring before it is forwarded. Leave this setting blank touse the value lhat is set in the Cisco CallManager Service parameter Forward No AnswerTimer. The default is 12 seconds.

Note When the voice mailbox is checked, Cisco Unified Communications Manager ignores the

settings in the Destination box and Calling Search Space fields.

Shared Lines

This subtopic describes shared lines in Cisco Unified Communications Manager.

Shared Lines

Same directory number configured on multiple IP phones.

All IP phones will ring at the same time ifthe directory number iscalled.

The call can be taken from any of the IP phones. All other IP phonesstop ringing when the call is answered.

All users with directorynumber 1000 can

answer Ihe call.

1000

User A dialed directorynumber 1000

UserB

A shared line is implemented by assigning Ihe same directory number to multiple phones in thesame partition. Ifthe number is called, all phones that are configured with this shared finedirectorv number will ring. The first user that accepts the call is conneclcd to the caller and allother phones stop ringing.


Shared Lines with Barge and PrivacyThis subtopic describes shared lines wilh the Barge and Privacy features.

Shared Lines with Barge and Privacy

• With the Barge feature, users can add themselves to anactive call on a shared line.

• There are two ways to use barge functionality:

The Barge softkey uses the built-in conference bridge.

cBarge uses a conference bridge (media resource),

* Privacy prevents other users on a shared line from viewingcall information or from barging into the call.

fhe Barge feature allows a userto be added to a remotely active call thai is on a shared line. Anactive call on a shared line is an active (connected) call that is made to or from another devicethat shares a directorv number with Ihe line. Barge supports this type of remote-in-use call.

Phones support Barge in two conference modes:

• Huilt-in conference bridge at Ihc target device (the phone that is being barged): fhismodeuses the Bargesoftkey. This tvpe of bridgedoes not utilizethe Cisco IP Voice MediaStreaming Application and is limited to three streams.

• Shared conference bridge: This mode uses the cBargesoftkey. This type of bridgeusesthe Cisco IP Voice MediaStreaming Application and is only limited by the conferencebridge being used for a conference.

Bv pressing the Barge orcBarge softkey in the remotc-in-use call state, the user isadded to thecallwith all parties, andall parlies receive a barge beep tone (if configured). If Barge fails, theoriginal call and status remain active. Ifnoconference bridge isavailable (built-in orshared),the Barge request is rejected anda message displays at the barge initiator device.

Note The built-in conference bridge is not available on all IP phones.

With Ihe Privacv feature, administrators can enable or disable the capability of users withphones that share the same line (directory number) to view call status and to barge the call.Administrators enableor disable Privacy for each phoneor globally in the serviceparameters.

Call PickupThis subtopic describes the Call Pickup feature.

Call Pickup

Each pickup group is identified by a unique pickup group number.

Each phone line can be a member of one pickup group.

Allows users to pick up incoming calls within their own group.

Cisco Unified Communicalions Manager automatically dials the configuredcall pickup group number when a user presses Ihe PickUp softkey.

Call Pickup Group

1 Calls User C with

extension 1002

4. User B and D can

answer the call.

3. User B and D

are notified.

2. User C cannot

answer the call.

Cisco Unified Communications Manager allows multiple lines to be grouped into pickupgroups. Each pickup group is identified by a unique pickup group number, which is part ofthecall routingtabic in Cisco Unified Communications Manager. A phoneline can be assigned toone pickup group.

If a phoneringsbut there is nobody to answer the call, anotheruser can pick up the call by-usingthe Call Pickup feature ifthe ringingphoneis in the samepickupgroup as the phoneofthe userwhowants to pickupthecall.Theadministrator candefine when otherCall Pickupgroup members are notified aboutan incoming call in theirCall Pickup group. Additionally, thenotification type can be modified to allow audible and visual notifications. Within the samegroup, the longest alerting call (longest ringing time) is picked up first if multiple incomingcalls occur in the group.


Directed and Group Call PickupThis subtopic describes the Directed Call Pickup and Group Call Pickup features.

Directed and Group Calf Picks

Allows users to pick up incoming calls from another group.

After pressing the GPickUp button, users must enter the appropriatepickup group number.

Directed Call Pickup allows users to pick up a call from otherphones by pressing the GPickUp softkey and entering the directorynumber

Other Group Call PickupThis subtopic describes the Other Group Call Pickup feature.

Other Group Pickup

• Allows users to pick up incoming calls ina groupthat is associatedwith their own group.

• Cisco Unified Communications Manager automatically searches forincoming calls in associated groups when theuseractivates thisfeature.

• Uses the OPickUp softkey.Call Pickup Group

Number 4000

Call Pickup GroupNumber 5000

"Ihe Other Group Call Pickup feature allows users to pick up incoming calls in agroup that isassociated with their own group. Cisco Unified Communications Manager automaticallysearches for incoming calls in the associated groups tomake the call connection when the useractivates this feature from an IPphone. Use theOPickUp softkey for this type of call pickup.When more than oneassociated group exists, thepriority of answering calls for theassociatedgroup goes from the first associated group tothe last associated group.

Eor example, groups A. B. and Cassociate with group X, and the priority ofanswering callsgoes togroup A. then group B, and then group C. Within asingle group, the call with thelongest ringing time ispicked up first. Eor Other Ciroup Call Pickup, priority takes precedenceover the ringing time ifmultiple associated pickup groups are configured. Both the idle and off-hook call states makethe Pickup, GPickUp. and OPickUpsofikeysavailable.

Call Pickup. Group Call Pickup, and Other Group Call Pickup can be automated by enablingthe sen ice parameter Auto Call Pickup Enabled. When this parameter isenabled, CiscoUnified Communications Managerautomatically connects users to an incoming call in theirown pickup group, inanother pickup group, or ina pickup group that isassociated with theirown group when a user presses the appropriate softkey onthephone. Auto Call Pickupconnects the user lo an incoming call. Whenthe user pressesa pickupsoftkey on the phone,Cisco Unified Communications Managerlocatesthe incoming call and completes the callconnection. If automation is not enabled, the user must press the Pickup and Answer sofikeys toreceive the call.

Call Park is tvpically used in one of two ways: (I) an operator needs to send a call to a personwhose location is unknown or (2) a phone user wants to move a caller from one phone toanother.

fhe phone user is on a call but wants to move the call to another extension. The user pressesthe Park softkey and notes the park zone number on the phone display. The user moves to thenew phone, dials the park /one number, and resumes the call.

Call Park places the call on hold for 60 seconds by default. Ifthe timer expires before fhe call isretrieved, the call will ring on the phone that placed it on park.

A range of park numbers needs to be assigned to each Cisco Unified Communications Managerin ihe cluster that will be handling call processing. Park /ones are issued to calls from the CiscoUnified Communications Manager server lo which the phone is registered. While there will bedifferent number ranges for each Cisco Unified Communications Manager, the call can bepicked up bv anv phone, regardless ofthe Cisco Unified Communications Manager to whichthe retriev ing phone might be registered. This situation is another reason why ihe personplacing the call on park must note the park number. This number will clear from the displav in10 seconds by default.

The Directed Call Park feature is accessed differently than Call Park. Directed Call Park doesnot use a soitkev. Instead, it uses the transfer softkey to direct Ihe call lo the directed call parknumber specified bv the IP phone user. This process allows end users to use a specifiedDirected Call Park number every time without the need to note a new number from a definedrange vvhen parking a call, flic Directed Call Park number can be watched with a Directed CallPark busv lamp field (Bl.F). which allows users lo see if a call is currently on the specifiedDirected Call Park number.

2. Two-Way Intercom Call UserB

2. User at phone B receivesspoken message of user Alone-way audio whisper). By pressinga key, a two-way intercom callcan be established.

With an intercom fine, end users can call the intercom line of another user and isautomaticallyconnected tothe caller. Aone-way audio call has now been established between the initiatorand the recipient. The recipient can hear the initiator ofthe call, but the voice ofthe recipientwill notbestreamed to the initiator. The recipient can then acknowledge thewhispered call andinitiate a two-way intercom call by pressing the intercom line on his orher Cisco Unified IPphone.

fhe administrator can use an intercom line to dial any other intercom line, or use apreconllgured line to a single specific target intercom line.

Thecalled destination autoanswers thecall in speakerphone mode withmute activated. Thisprocess sets up aone-way voice path between the initiator and the destination, so the initiatorcandeliv er a short message, regardless of whether thecalled party is busy or idle.

Toensure that the voice ofthe called party isnotsenl back to thecaller by the automaticallyanswered intercom call. Cisco Unified Communications Managerimplements whisperintercom. Whisper intercom means that only one-way audio exists from the caller tothe calledparty until ihc called party accepts the intercom call by pressing the intercom phone button.When the called party accepts the intercom call, the call becomes a full two-way audio call.

Note Anauto answer tone marks the beginningof the whisper state for both the sender and the

recipient.

Intercom lines on IP phones can beconfigured with a speed dial, which disallows users to usethe intercom lineto dial otherintercom lines. With a speed dial, thedestination isdialedimmediately when the intercom line is offhook. Without aspeed dial, the user must know theintercom extension of anotheruser and the extensionmust be dialedmanually.

Intercom lines use their own permissions, which are similar topartitions and CSSs for normaldirector, numbers. Intercom users candial any otherintercom linewhen the partitions and CSSare configured properly. The intercom configuration process automatically creates CSSs whena partition is added. By default, intercom dial plan architecture isa two-user setup The two-usersetup means that CSSs are created to support permissions for two intercom line users.

Cisco Unified CommunicationsManager Presence Characteristic;

• Natively supported by Cisco Unified CommunicationsManager:

Support for SCCP lines, SIP lines, and SIP trunks

• Allows a watcher tomonitor the real-time status ofa directorynumber.

• Watchersubscribes to status information ofthe presenceentity.

« Watchercan show the status ofa presence entity using:Presence-enabled speed dials

Presence-enabled lists (calland directory lists).• Three possible states of watched directory number:

5S Entity is unregistered£3 Entity is registered—on hookf#>Entity is registered—off hook

Presence is iiativelv supported bv Cisco Unified Communications Manager, and no extraproducts or serv ers are required. It allowsan interested party, the watcher or subscriber, tomonitor ihcreal-time status of a directorv number or any presence entity.

A watcher subscribes to thestatus information of one or more presence entities. Thestatusinformation ofa presence entity can be viewed using presence-enabled speed dials orpresence-enabled lists call lists such asplaced, received, or missed calls and public directory lists.

fhe status can he one ofthe following:

• Unknown: fhis status is shown vvhen the watched device is unregistered.

• On hook

• Off hook


Presence Status on IP PhonesIP phones can display status information (unknown, on hook, or off hook) of presence entitiesbv presence-enabled speed dial or call and directory list entries.

Presence Status on IP Phones

The presence status can be seen on speed-dialbuttons, call lists, and directories.

Presence-enabled speed dials show a symbol inthe screen ofIhe IP phone, which islocated atthe appropriate speed dial button. Some phone models have an LED inside the speed dialbutton and indicate the status byred(offhook), green (onhook), or flashing (alerting) lights.

When browsing through a directory orcall list, each entry displays a symbol indicating itscurrenl status.

BLF Call Pickup1he Bus; [.amp field (BLF)Call Pickup feature allows end userslo monitorIhecurrent lineslate of a user.

BLF Call Pickup

A Busy Lamp Field (BLF) can be configured with callpickup functionality:

• When a BLF indicates alerting of a directory number, user Acan press the BLF button.

• Call is then displayed on the IP phone and can be picked orautomatically connected if configured.

An existing BLFbutton on an IPphone can be configured with call pickupfunctionality. If ihewatched numberis ringing, the subscriberof this numbercan pressthe BLFCall Pickup buttonon the IP phone. Dependingon the configuration, the call is directly picked up and answered, orthe call is displayed on the IP phoneofthe subscriber. Ifthe call is displayed on the IP phone,the subscriber must manuallv answer the call bv going off hook or pressing his phone button onthe phone where the directory number ofthe user is configured.

Limiting Presence Visibilityfhis subtopic describes how to limit presence visibility.

Limiting Presence Visibility

Cisco Unified Communications Manager presenceoffersdifferent ways to limit visibility of presenceinformation:

• Presence-enabled speed dials;

- Statically configured byCisco Unified CommunicationsManager Administrator

- Subscribe CSS and partitions

• Cannot be configured by end users

• Presence-enabled call and directory lists;

- Subscribe CSS and partitions

- Presence groups

Cisco Unified Communications Manager presence can limit visibility ofpresence infomiationin the following ways:

• Presence-enabled speed dials are configured statically by the Cisco UnifiedCommunications Manager administrator and cannot be configured ormodified by auser. Inthis wav. the administrator has control over the monitored presence entities for eachindividual watcher. However, partitions and Subscribe calling search spaces also apply topresence-enabled speeddials.

• Access control for presence-enabled call and directory lists can be provided by partitionsand Subscribe calling search spaces and by presence groups. These two methods can beused independently ofeach other. Ifboth are used, both must permit a subscription forsuccessful watching ofthe presence entity status.

Subscribe CSS

Thissubtopic describes how Subscribe CSSs work.

Subscribe CSS

• User needs permission to monitor the presence entity:Subscribe CSS

Presence group

• The Subscribe CSS is associated with the watcherand liststhe partitions that the watcher is allowed to see:

This mechanism provides an additional level ofgranularity.

Can be assigned on a device or user basis for CiscoExtension Mobility.

Partition Devices

II the watcher has permission tomonitor the external presence entity thai is based on theSubscribe CSS and presence group, the SIP trunk will forward the presence request lo theexternal presence entity. await the presence response from the external presence entity, andreturn the current presence status lo the watcher.

Cisco Unified Communications Manager provides ihe capability to set policy for users whorequest presence status. This policy can beset by configuring a CSS specifically lo route-Session Initiation Protocol (SIP) subscribe messages for presence status. This policy can alsobe set by configuring presence groups that specify rules for viewing the presence status ofusersthat are associaled with another group. Users can then be associated with the presence group.The first aspeel ofpresence policies for Cisco Unified Communications Manager is theSubscribe CSS, Cisco Unified Communications Manager uses the Subscribe CSS todeterminehow to route presence requests (subscribe messages with the Lvent field setlo Presence) thatcome from the watcher, whichcan be a phone or a trunk. The Subscribe CSS is associated withthe watcher and lists the partitions that the watcher is allowed tosee. This mechanism providesan additional level ofgranularity for the presence subscribe requests lo be routed independentlyfrom the normal call-processing CSS.

1he Subscribe CSS can be assigned on a dev ice basis oron a user basis. The user sellingapplies fororiginating subscriptions when the useris logged in to thedevice viaCisco UnifiedCommunications Manager Intension Mobility orwhen the user isadministratively assigned tothe device.

With the Subscribe CSS setto<None>. BLF speed dial and call history listpresence statusdoes not workand the subscription messageis rejected as ••user unknown." When a validSubscribe CSS isspecified, the indicators work and ihe subscribe messages are accepted androuted properly, Cisco strongly recommends not defining any CSS as <Nonc>. Leaving a CSSsetto<None> can introduce presence status or dialing plan behavior that isdifficult to predict.

Presence Groups

Devices, directory numbers, and users can be assigned to apresence group, and bv default allusers are assigned to the same Standard Presence group. Apresence group controls thedestinations lhat a watcher can monitor, based on Ihe association ofa user with a definedpresence group (for example, employees watching managers is disallowed, but managerswatchingemployees is allowed).

Cisco Unified Communications Manager ExpressFeatures

This topic describes call features in Cisco Unified Communicalions Manager Impress. Thefigure shows the Cisco Extension Mobility feature.

Cisco Extension Mobil

Cisco Extension Mobility canbe configured with a VoiceLogout Profile:• AVoice Logout Profile is bonded

to an ephone.

- Voice Logout Profiles are usedwhen no user is logged in, andcan be configuredwith a defaultextension.

- User needs a Voice User Profileto log in on an ephone.

• Login is configured as a serviceon the IP phone; user needscredentials to perform loginprocess

Voice Logout Profile

Cisco Extension Mohilitv provide users with the ability to use any Cisco Extension Mobility-enabled Cisco IP Phone as thev would use their own phone, by logging in and having theirpersonal user profile overlay the profile ofthe original phone setup,for example, if outside sales personnel visit an office occasionally, they may not have apermanent desk and phone, but may instead work at atemporary desk. Using Cisco ExtensionMobility, the visitinc worker can log in to the phone al the temporary desk, he user can henretrieve'voiee mail and place calls using the extension number and features that they wouldnormally have available on their own office phone.Cisco Extension Mobility in Cisco Unified Communications Manager Express is based onlooout profiles, which are bonded to an ephone. Alogout profile defines the detault appearancefor an IP phone thai is enabled for Cisco Extension Mobility. Iogoul profiles can be configuredwith adefault extension and oilier settings thai are applied when nobody ,s logged in to aspecific ephone.Isers must log in auser profile in order to use .he features that are available on their own office

Call Forwarc

1his suBtopic describes call forward options inCiscoUnified Communications ManagerExpress

Call Forward

Cisco Unified Communications Manager Express hasdifferent call forward options:• Call Forward All can be configured on the IP phone.

• CFA, CFNA, and CFB can be defined via CLI, GUI, or CiscoConfiguration Professional.

• Call Forward No Answer must be defined with a no answer timer.

• Night Service allows users to forward incoming callsautomatically during configured night service hours.

In Cisco Unified Communications Manager Express, CFA canbeconfigured by the phone userin thesame wayas it is configured in Cisco Unified Communications Manager. It canbeconfigured from the user web page, at the phone itself, or from the adminislrator web interface,thecommand-line interface (CLI), or Cisco Configuration Professional. IfCFA isconfigured,the call is forwarded immediately without ringing theoriginally dialed phone. CFNA andCEBcan only be defined by the administrator from the CLI, the web interface, or via CiscoConfiguration Professional. CFNA requires a timer, which defines the lime at which a call isdeclared asnotanswered. Cisco Unified Communications Manager Express also has a NightSen ice feature, which allows calls tobe forwarded during predefined night hours (nonbusinesshours). During these times, calls are automatically forwarded toanother IP phone.

Night Service

5-30

The Night Sen ice feature allows administrators to provide coverage for unslaffed extensionsduring hours that arc designated as "night senice" hours.

The Night Service features provides call forwarding duringdefined night service times:

• An ephone-dn can be designated as the NightService Bell.

- Night Service can be a day, a date, a defined time frame, weekdays,or during weekends

• Can be configured witha code to toggle the NightService on/off.

Night Service Configured forSaturday and Sunday

During the night-sen ice hours, calls to the designated extensions send aspecial '"burst" ring tophones that have been specified to receive this special ring. Phone users at the night-senicephones can then use the Call Pickup feature to answer incoming calls from ihe night-serviceephone-dns. The Might Sen ice feature can be extended with automatic call fonvards duringnight-senice hours.

Eor example, the Night Sen ice feature can allow an employee working after hours to interceptand answer calls lhat are presented loan unattended receptionist phone. When acall arrives atthe unattended receptionist phone during hours that are specified as night service, a ring burstnotifies aspecified set ofphones ofthe incoming call. Aphone user al any ofthe night-senicephones can intercept the call using the Call Pickup feature. Night-senice call notification issent every 12 seconds until the call is answered or aborted.

An optional configuration allows the phone user to manually toggle night senice on and offfrom any phone that has aline that is designated as anight-senice line. When night senice isactive, the niuni-sen ice phones display a message.

Shared Ephone-dnsShared ephone-dns are used toprovide call coverage for the same number on different ephones.This method allows end users to pick up an incoming call onmore than one IP phone. Forexample, for teams, use a shared linecan be used lo provide call coverage forcentral call-innumbers or basic hotline features.

The same ephone-dn is applied to two differentephones.

Only one phone can use the ephone-dn at a time

Both IP phones nng when a call arrives at theephone-dn. but only one ephone can pick up the call

Either ephone can retrieve a call placed on hold.

UserC

A shared ephone-dn has the following characteristics:

• It appears on different phones, but uses the same ephone-dn and number.

• Ifthe ephone-dn is connected to a call on one phone, thai ephone-dn is unavailable forother calls on the second plione because the phones share the same ephone-dn. fhe activecall appears on both phones.

• Both phones ring when a call arrives at the ephone-dn but only one phone can pick up acall, which ensures privacy.

• When a cull is placed on hold, either phone can retrieve il.

• Use shared ephone-dns when the ability lo answer or pick up a call at more than one phoneis necessan.

3all Pickup Groups

Cisco Unified Communications Manager Express supportsthree different Call Pickup types:

Local Group Pickup

- Allows pickup from the same call pickup group.

- User presses the GPickUp softkey and asterisk (*) to pick up anincoming call.

Directed Call Pickup

Direct call pickup from a ringing extension.

- A user does not need to belong to a pickup group to use thisfeature

Different Group Pickup

- Users can pick up a call from any group by pressing theGPickUp softkey and dialing the pickup group number.

- If only one pickup group is configured, users need to press onlythe GPickUp softkey.

Call Pit kup has the following variations:

• Lot al Group Pickup: Call Pickup, local group ringing extension. Phone users can pick upthe called number on another phone in their local group by pressing the Pickup softkey plusthe iasterisk (*) on their own phone.

• Directed Call Pickup: Call Pickup, explicit ringing extension. Any local phone user canpick up a call that is on hold on another directory number in Cisco UnifiedComniunications Manager Express. The phone user does not need to belong to a pickupgroup to use this method. This behavior is a default behavior.

• Different Group Pickup: Call Pickup, explicit group ringing extension. Phone users cananswer a ringing phone in any pickup group ifthe user knows the group number oftheringing phone. If there is only one pickup group that is defined in Cisco UnifiedComniunications Manager F.xpress, the phone user can pick up the call by pressing thePickup softkey. The phone user does not need lo belong lo a pickup group to use thismethod.

Administrators can assign each ephone-dn independently to a maximum of one pickup group.There is no limit to how many ephone-dns can be assigned to a single pickup group. There is nolimit to how many pickup groups can be defined in a Cisco Unified Communications ManagerL.xprcss.

Intercom

This subtopic describes the Intercom feature in Cisco Unified Communications ManagerFxpress.

Intercom

Intercom lines working like theydo in Cisco Unified

Communications Manager:

• Configured as an additional line onthe phone buttons.

• Intercom directory numbers can bedialed from any IP phone.

• To avoid dialable numbers, assignan alphabetic character to thenumber, for example, A B, C, orD.

Manager

Line 1 - 1001

Line2-A1001

Assistant

Line! -1002

Une2-A1002

An intercom line is a dedicated two-way audio path between two phones. The called phoneautomatically answers the call in spcakerphone mode wilh mule activated, which provides aone-way voice path from the initiator to the recipient. A beep is sounded when the call is autoanswered to alert the recipient to the incoming call. To respond to the intercom call and open atwo-way voice path, the recipient deactivates the mule function by pressing the Mule button orby lifting the handsel.

The administrator can deaclivate the speaker-mute function on intercom calls. For example, ifphone user I makes an intercom call to phone user2, both users heareach otheron connectionwhen the no-mute function is configured using the intercom command. The benefit is thaipeople who receive intercom calls can be heardwithout havingto disablethe mute function.The disadv antage is that nearby background soundsand conversations can be heard at themoment when a person receives an intercom call, regardless of whether they are ready to take acall or not.

Intercom lines cannot be used in shared-line configurations. If a directory' number is configuredfor intercom operation, it must be associated wilh only one IP phone. The intercom attributecauses an IP phone line to operate as an autodial line for outbound calls and as an auto answer-with-mute line for inbound calls.

To prevent an unauthorized phone from dialing an intercom line, administrators can assignanintercom a directorv number lhat includes an alphabetic character. No one can dial thealphabetic character from a normal phtme, but thephone at theother end ofthe intercom can beconfigured to dial ihe number lhatcontains thealphabetic character through ihc Cisco UnifiedCommunications Manager Fxpress router. Forexample, the intercom ephone-dns in the figurearc assigned numbers with alphabetic characters so that only the assistantcan call the manageron his or her intercom line, and no one except the manager can call the assistant on his or herintercom line.
