Understanding the Cisco Unified Wireless IP Phone 7921G

The Cisco Unified Wireless IP Phone 7921G provides wireless voice communication over an IP
network. Like traditional analog telephones, you can place and receive phone calls and access features
such as hold, transfer, and speed dial. In addition, because the phone connects to your wireless local area
network (WLAN), you can place and receive phone calls from anywhere in your wireless environment.
The Cisco Unified Wireless IP Phone 7921G is an 802.11 dual band wireless device that provides
comprehensive voice communications in conjunction with Cisco Unified Communications Manager and
Cisco Aironet 802.11b/g and Cisco Aironet 802.11a Access Points (APs) in a private business
communications network. This phone model, like other network devices, must be configured and
managed. This phone encodes G.711a, G.711u, G.729a, G.729ab, G.722/iLBC, and decodes G.711a,
G711b, G.711u, G.729, G729a, G729b, and G729ab. The phone also supports uncompressed wideband
(16 bits, 16 kHz) audio.
The wireless IP phone supports multiple lines and most of the IP phone features of other Cisco Unified
IP Phones.
