Chapter 1 An Overview of the Cisco Wireless IP Phone 7920

Networking Protocols Used with Cisco Wireless IP Phones

Wireless network devices use a service set identifier (SSID).The SSID provides a way to group a set of user devices that can associate with a set of access points. Each wireless device that can use the access point is configured with the same SSID as the AP.

Security

All wireless LAN traffic is seen by all other WLAN devices that are within range, so securing voice communications is important. To ensure that voice traffic is not manipulated or intercepted by intruders, the Cisco Wireless IP Phone 7920 and Aironet APs are supported in the overall Cisco SAFE security architecture.

The Cisco Wireless IP Telephony solution provides the following additional security areas:

•Network access security to prevent unauthorized logins by using encryption and authentication with wireless encryption protocol (WEP) and Cisco Light Extensible Authentication Protocol (LEAP) and the elimination of rogue APs.

•Password protection for directories and databases including a Cisco Wireless IP Phone 7920 phone lock password.
