Chapter 6 Customizing the Cisco Unified IP Phone Configuring Wideband Codec 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 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 affect whether wideband is supported for this Cisco Unified Communications Manager server and/or a specific phone: • Advertise G.722 Codec-From Cisco Unified Communications Manager, choose System > Enterprise Parameters. The default value of this enterprise parameter is True, which means that all Cisco Unified IP Phone Models 7906G, 7911G, 7941G, 7941G-GE, 7961G, 7961G-GE, 7970G, and 7971G-GE that are registered to this Cisco Unified Communications Manager will advertise G.722 to C.isco 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-From Cisco Unified Communications Manager, 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.
