Configuring the Cisco 7920 Wireless IP Phone

The Cisco 7920 Wireless IP Phone is supported by Cisco CME 3.0 and later. This phone is configured like any other wireless device. Go to http://www.cisco.com/go/wireless for more information on setting up your wireless network for voice traffic.

The Cisco CME configuration required for a Cisco 7920 Wireless IP Phone is no different from any of the other IP phones discussed in the previous sections. This phone requires certain firmware depending on the version of Cisco CME you are using. This firmware version should be configured in telephony-service configuration mode. You also can configure the phone manually from the phone's menu.
