Chapter 6 Customizing the Cisco Unified IP Phones
Configuring Wideband Codec
Note Cisco recommends that you also store backup copies of custom image files in another location.
You can use these backup copies if the customized files are overwritten when you upgrade
Cisco Unified Communications Manager.
Step 4 Use a text editor to edit the List.xml file. See List.xml File Format Requirements, page 6-4 for the
location of this file, formatting requirements, and a sample file.
Step 5 Save your modifications and close the List.xml file.
Note When you upgrade Cisco Unified Communications Manager, a default List.xml file will replace
your customized List.xml file. After you customize the List.xml file, make a copy of the file and
store it in another location. After upgrading Cisco
Unified Communications Manager, replace
the default List.xml file with your stored copy.
Step 6 To cache the new List.xml file, stop and start the TFTP service by using Cisco Unified Communications
Manager Serviceability or disable and re-enable the Enable Caching of Constant and Bin Files at Startup
TFTP service parameter (located in the Advanced Service Parameters).
Configuring Wideband Codec
If Cisco Unified Communications Manager has been configured to use G.722 (G.722 is enabled by
default for the Cisco
Unified IP Phone 7962G and 7942G) and if the far endpoint supports G.722, the
call can connect using the G.722 codec in place of G.711. This situation occurs regardless of whether
the user has enabled a wideband headset or wideband handset, but if either the headset or handset is
enabled, the user may notice greater audio sensitivity during the call. Greater sensitivity means
improved audio clarity but also means that more background noise can be heard by the far
endpoint—noise such as rustling papers or nearby conversations. Even without a wideband headset or
handset, some users may prefer the additional sensitivity of G.722. Other users may be distracted by the
additional sensitivity of G.722.
Two parameters in Cisco Unified Communications Manager Administration affect whether wideband is
supported for this Cisco Unified Communications Manager server or a specific phone:
• Advertise G.722 Codec—From Cisco Unified Communications Manager Administration, choose
System > Enterprise Parameters. The default value of this enterprise parameter is True, which
means that all Cisco Unified IP Phone models that are described in this administration guide and are
registered to this Cisco Unified Communications Manager will advertise G.722 to Cisco Unified
Communications Manager. For more information, see the Cisco Unified Communications Manager
System Guide
, Cisco Unified IP Phones chapter.
• Advertise G.722 Codec—From Cisco Unified Communications Manager Administration, choose
Device > Phone. The default value of this product-specific parameter is to use the value specified
in the enterprise parameter. If you want to override this on a per-phone basis, choose Enabled or
Disabled in the Advertise G.722 Codec parameter on the Product Specific Configuration area of the
Phone Configuration window.
