Set Up Wideband Codec
By default, the G.722 codec is enabled for the Cisco IP Phone. If Cisco Unified Communications Manager
is configured to use G.722 and if the far endpoint supports G.722, the call connects 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 the far endpoint can hear more background
noise: 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 distracting. Other users may prefer the additional
sensitivity of G.722.
The Advertise G.722 and iSAC Codec service parameter affects whether wideband support exists for all
devices that register with this Cisco Unified Communications Manager server or for a specific phone, depending
on the Cisco Unified Communications Manager Administration window where the parameter is configured.
Procedure
Step 1 To configure wideband support for all devices:
a) From Cisco Unified Communications Manager Administration, choose System> Enterprise Parameters
b) Set the Advertise G.722 and iSAC Codec field
