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.

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.
