Product Architecture
For point-to-point wideband calls, both Cisco Unified IP phones must be equipped with a Cisco
Unified Wideband Handset, and must have the G.722 wideband codec enabled within the phone
and within the network. Cisco Unified Communications Manager 4.1 or later is required to support
the G.722 wideband codec.
The Cisco Unified Wideband Handset is currently supported on Cisco Unified IP Phone 7906G,
7911G, 7941G, 7941G-GE, 7961G, 7961G-GE, 7970G, and 7971G-GE models only. Other Cisco
Unified IP Phone 7900 models do not support the Cisco Unified Wideband Handset.
When using the Cisco Unified Wideband Handset, the host IP phone must be loaded with
Firmware Cisco IP Phone Firmware Release 8.3(1) or later. Use of firmware releases earlier than
8.3(1) are used could result in compromised voice quality and the phone will no longer meet
Regulatory Compliance for FCC Part 68 (Hearing Aid Compatibility), Australia S004 and S040, and
New Zealand PTC 220. To verify the firmware version, please go to Settings > Status > Firmware
Versions > Load File. If the firmware version is earlier than 8.3(1), then notify your network
administrator or reseller.
