Network Services: DNS
Cisco Unified Communications Manager can use DNS names (default) or IP
addresses for system addressing.
Advantages of Using IP Addresses Advantages of Using DNS
Does not require a DNS server. Simplifies management because of the use of names
instead of numbers.
Prevents the IP telephony network from failing when
the DNS server is unavailable.
Easier IP address changes because of name-based
IP paths.
Decreases the amount of time required when a
device attempts to contact the Cisco Unified
Communications Manager server.

Phone NTP Reference ensures that a Cisco IP
SIP phone gets its date and time from the NTP
server. If NTP servers do not respond, the
Cisco IP SIP phoneuses the date header in
the 200 OK response.
Phone NTP Reference and Date/Time Group
▪ Date/time groups define time zones for devices that are connected to Cisco Unified Communications Manager.
▪ Date/time group is assigned to the device pool.
▪ The device pool is assigned to the device.
▪ Device pools define sets of commoncharacteristics for devices.
▪ The device pool structure supports the separation of user and location information.
▪ The device pool contains only device-and location-related information.
Device Pool
▪ A Cisco Unified Communications
Manager Group specifies a
prioritized list of up to three Cisco
Unified Communications Manager
servers.
▪ The first Cisco Unified
Communications Manager in the list
serves as the primary Cisco Unified
Communications Manager for that
group, and the other members of
the group serve as secondary and
tertiary (backup) Cisco Unified
Communications Manager servers.
Cisco Unified CM Group
▪ Use regions to specify the bandwidth that is used
for an audio or video call within a region and
between regions by codec type.
▪ The audio codec determines the type of
compression and the maximum amount of
bandwidth that is used per audio call.
Region and Location
▪ Use locations to implement CAC in a
centralized call-processing deployment.
▪ CAC enables you to regulate audio quality and
video availability by limiting the amount of
bandwidth that is available for audio and video
calls.
▪ In the Enterprise Phone
Configuration window,
parameters can be configured
that will apply to all phones
that support these parameters.
▪ Select the "Override Common
Settings" box for each setting
you wish to update. If you do
not check this box, the
corresponding parameter
setting does not take effect.

Phone Settings
Softkey template configuration allows the
administrator to configure softkey layouts
that are assigned to Cisco Unified IP
phones.
Choose Configure Softkey
Layout to configure the softkey
layout.
Softkey Template
1. Choose the
phone state.
2. Assign softkeys
for the selected
phone state.
Phone button templates specify how the phone buttons of a Cisco IP phone should be used.
Options include lines, speed dials, and functions such as callback, Call Pickup, etc. Each Cisco
IP phone has one phone button template assigned.
Phone Button Template
A SIP profile comprises the set of SIP attributes that
are associated with SIP trunks and SIP endpoints.
SIP profiles include information such as name,
description, timing, retry, Call Pickup URI, etc.
SIP Profile and Common Phone Profile
Common phone profiles include phone configuration
parameters and are assigned to IP phones.

PSTN Access Digit Manipulation Example
Step Description
1 Extension 1005 dials 913035556007.
2 Dialed number matches 9.!. route pattern configured with the following:
• Called-party transformations > Discard digits: PreDot
• Calling-party transformations: 40855530XX
3 Cisco Unified Communications Manager strips off (discards) digit 9 from the dialed number and
sends 13035556007 to PSTN via the Gateway, after modifying the calling-party number from 1005
to 408 5553005.
4 The PSTN phone 303 5556007 rings and sees 408 5553005 as the calling number.
Digit Manipulation Flow Example (Incoming Call from PSTN)
Step Description
1 PSTN phone dials 14085553010; PSTN switch routes the call to the gateway and Cisco Unified CM.
2 • Incoming called dialed number matches 40855530XX translation pattern, configured as follows:
– Called-party transformation > Called-party transform mask: 10XX
– (Optional) Calling-party transformation > Prefix digit: 91
3 • Cisco Unified CM translates 408 5553010 to 1010.
• Cisco Unified CM looks up 1010 and finds a registered phone with that directory number.
4 Cisco Unified CM presents the call to extension 1010. The Cisco Unified CM optionally (see Step 2)
prefixes the calling number with 91 to allow the internal user to call back the PSTN caller from an IP
phone via the Directory button.
