Overview of the Cisco Unified Wireless
IP Phone 7925G, 7925G-EX, and 7926G
The Cisco Unified Wireless IP Phone 7925G, 7925G-EX, and 7926G 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.
This chapter includes the following sections:
Understanding the Cisco Unified Wireless IP Phone 7925G and
7926G
The Cisco Unified Wireless IP Phone 7925G and 7926G 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.
The phone is a qualified Bluetooth wireless device (Qualified Device ID [QDID] B014396). The phone
provides voice communication over the same wireless LAN that your computer uses, allowing you to
place and receive phone calls, put calls on hold, transfer calls, make conference calls, and so on.
This phone model, like other network devices, must be configured and managed. This phone encodes
G.711a, G.711u, G.729a, G.729ab, and G.722/iLBC codecs, and decodes G.711a, G711b, G.711u,
G.729, G729a, G729b, and G729ab codecs. The phone also supports uncompressed wideband (16 bits,
16 kHz) audio.
