solutions based on its SIP Server
platform, capable of supporting a
"PBX free" environment for
contact centers, than those based
on its traditional T-Server
platform, indicating the company's
strengthening performance in
selling its emerging technologies.”

Sizing and Scaling SIP Server Scaling
SIP Server SIP Server supports full hot
standby Up to 150 direct calls per sec per
instance of SIP Server Up to 15,000 End points monitored
per instance of SIP Server
Load balancing with Network SIP Server Use of Network SIP Server to load
balance over multiple instances of SIP Server
Network SIP Server can handle up to 400 calls per sec (based on Redirect)
Global scalability Tested to 30,000 agents Potentially can scale much higher

Enabling Alternate Ringtones
Alternate ringtones can be supported by sending additional information in the SIP Headers
When SIP Server generates a new call via an INVITE, it can add the Alert-Info header, endpoints can then interpret this for custom ringtones
The option sip-alert-info details the ringtone or ringtone location for the endpoint to play. Similar options sip-alert-external and sip-alert-consult apply specifically to
external or consult calls

Media Server Reliability—MSML
SIP Server supports the SIP SUBSCRIBE/NOTIFY method for providing reliable MSML-based media services through Genesys Media Server. By subscribing to the DN used to represent Genesys Media Server for msml-based services, SIP Server is able to determine when a particular instance of Media Server becomes unavailable, and if so, SIP Server can disconnect from the failed media server, then reconnect to an available instance of Media Server, providing continuity for any ongoing msml-based media services.
1. SIP Server sends periodic SUBSCRIBE messages to GVP Resource Manager for each Voice over IP Service DN (service-type is set to msml ) that SIP Server is subscribed to.
2. If a particular instance of Media Server becomes unavailable, Resource Manager sends a NOTIFY message to SIP Server, which lists the status of each media server monitored by Resource Manager. A sample body for the NOTIFY message is as follows:
*msml/<mediaserver-ipaddress>:<mediaserver-port>/out-of-service*
3. SIP Server disconnects all ongoing media services from this Media Server instance, then reconnects with an active Media Server through Resource Manager.
4. All existing treatments and conference connections are re-established on the alternate Media Server instance.

UC Connector - Modes of operation with Lync
Lync voice integration: presence gateway mode
• Used only in the Contact Center in integration with Lync Voice
• Used to pass presence information between Lync and Genesys
• No UI: the UC Connector subscribes to Lync presence to get back to StatServer
• No licensing requirements: part of the SIP Integration license and package
• Users are not aware of the UC Connector - it is simply a component of the system
Enabling customer service for Knowledge Workers
• UC Connect package bundles CIM, SIP Server / T-Servers, and UC Connector
• Separate license needed
• Implements special routing / capabilities for Enterprise Knowledge Workers
• Provides Interaction Preview and 3PCC pop-up windows
• Also subscribes to Lync (or other UC system) presence to relay status to Genesys

SIP Server Voicemail Options
SIP Server now includes a new option, info-pass-through, that lets you control whether SIP Server will pass SIP INFO messages to a remote device. Configure this option on the destination DN. For example, if DN1 and DN2 are connected, and DN1 sends an INFO message to DN2, SIP Server analyzes the info-pass-through option on DN2 to decide if the INFO message should be passed through or filtered out.

Architecture Overview – Peered SIP Servers
1. Agent SIP endpoints have SIP registration on the both SIP Servers simultaneously.
2. Agent desktop normally logs into “Preferred Site” SIP Server, but logs into other site if preferred site is not reachable, or rejects login.
3. Peered SIP Servers check mutual availability and coordinate to deliver routed calls, internal calls and external calls to each agent via the SIP Server at which agent is logged in.
4. Agent desktop can connect to Config Server Proxy at either site, but gives preference to Desktop Preferred Site.
5. Current IW implementation utilizes simultaneous T-Lib connection to the both SIP Servers. However, Agent logged in on one site only.

Architecture Overview – Reporting
1. Redundant GIM instances at both sites operate in parallel, fed by ICON DBs at both sites.
2. ICON data that has not been transferred to GIM at time of site failure will be lost.
3. Users can retrieve historical reports from GI2 at either site.
4. Real-time reports: CC Pulse connects to Stat Servers at either site.
5. Every Stat Server monitors both SIP Servers.

Call Delivery – Premise Call Routing
.
1. A call arrives a SIP Server on Site 1.
2. SIP Server requests routing instructions from URS.
3. URS selects the best agent to handle the call. In this example, the selected agent is logged in on the other SIP Server. URS requests SIP Server to route the call to the agent. Agent Reservation must be enabled.
4. URS passes Site 2 in the location, so SIP Server transfers the call to the Site 2 SIP Server using ISCC.
5. Call is delivered to agent.
Media gateways distribute incoming traffic across both sites.
Site 1 Stat Server has visibility to agents logged into both SIP Servers

Call Delivery - DR-pair Target detection & Forwarding
• The Party that originates the direct inbound (or internal call) call does not know the current agent’s location. So call can arrive to any server in a DR pair.
• “Target Detection & Forwarding” procedure takes measures to deliver the call to the proper site in Business Continuity deployment.
- The procedure is applied to all calls to be delivered to the agent DNs.
- If destination is ready for call, call is delivered to it. Otherwise, call is forwarded to the DR-peer.
- This activity related to agent availability only. There is no intention to try the second site destination if phone is inaccessible on the first site.
- To avoid the infinitive loop of forwarding procedures in case of logged out agent, the forward SIP messaging includes private URI parameter in the ‘Contact’ (for 302) or ‘Refer-To’ (for ‘REFER’).
Contact: <sip:7101@dr-peer:5060;x-genesys-dr-forward>
- So, if call has been already forwarded from peer site then current SIP Server must try to deliver it to DN requested independently of agent status.

Failure detection
• Sip Server - Utilizes the dedicated trunk which points to its peer.
- Trunk name is defined in application option “dr-peer-trunk”.
- ”The ‘Out of Service’ check mechanism configured on this trunk provides the failure detection functionality( options “oos-check” and “oos force”.
• Desktop (T-Lib client) - Desktop must use the ADDP protocol to detect site availability.
SIP end point -failure detection depends on the phone model - Bria: Supports “Send SIP keep-alive” option. End point utilizes empty
messages sent to SIP port and relies on ICMP errors to detect
- Polycom SoundPoint: it does not have keep –alive mechanism. The failure could be detected by failing of outbound call or renewal of the registration.
- ALU 40xx uses OPTION request to check the SIP Server availability. Important that it does not continue sending OPTIONS to a dead site. So, it cannot detect the primary peer recovering. As result, it continues to work with secondary peer until failover on secondary site.

Graceful migration
• BC supports graceful migration of operations from two active/active SIP Server Peer sites to a single site
• Graceful migration includes administrative and automatic parts: 1. Configure your MGW to stop sending calls to the SIP Server Peer site that you intend to
shutdown.
2. Possible step is starting the dedicated strategies on URS.
3. Using Genesys Administrator, then initiate a graceful shutdown of the SIP Server
• During the graceful shutdown procedure SIP Server 1. Moves all agents into NotReady state
2. Logs out all agents who does not have active calls (with appropriate reason code ) and declares DN Out of Service
3. Rejects all INVITE with configurable final response (option “shutdown-sip-reject-code”)
4. Forbids any call created T-Request .
5. Rejects all agent login or ready requests.
SIP Server waits until last call is finished and then stops.
