G.722 Advertisement
Cisco Unified Communications Manager versions 5.0 and later support the ability to configure whether G.722 is to be a
supported codec system wide or not.
Earlier versions of Cisco Unified Communications Manager do not have this capability, where a Cisco Unified Wireless IP
Phone 7925G, 7925G-EX, and 7926G will attempt to use G.722 assuming the other endpoint also advertises G.722 capabilities.
If using a version of Cisco Unified Communications Manager prior to 5.0 and want to disable G.722 capabilities, then the latest
device package will need to be applied to the Cisco Unified Communications Manager to enable this product specific
configuration option where Advertise G.722 Codec can be disabled for each Cisco Unified Wireless IP Phone 7925G, 7925G-
EX, and 7926G.
For more information, refer to the Cisco Unified Communications Manager documentation.
