Chapter 6 Customizing the Cisco Unified IP Phone
Two parameters in Cisco Unified Communications Manager Administration
affect whether wideband is supported for this Cisco Unified Communications
Manager server and/or a specific phone:
•
•
Cisco Unified IP Phone 7961G/7961G-GE and 7941G/7941G-GE for Cisco Unified Communications Manager 6.0
OL-11953-01
Advertise G.722 Codec—Choose Cisco Unified Communications Manager
Administration > System > Enterprise Parameters. The default value of
this enterprise parameter is True, which means that all Cisco Unified IP
Phone Models 7941G, 7941G-GE, 7961G, 7961G-GE, 7970G, and
7971G-GE that are registered to this Cisco Unified Communications
Manager will advertise G.722 to Cisco Unified Communications Manager. If
each endpoint in the attempted call supports G.722 in its capabilities set, Cisco
Unified Communications Manager will choose that codec for the call.
Advertise G.722 Codec—Choose Cisco Unified Communications Manager
Administration > 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.
