Some authentication schemes require specific types of encryption. With Open authentication, you have the option to use static WEP for encryption and added security. But if you are using Shared Key authentication, you must set static WEP for encryption, and you must configure the WEP key on the phone.


When using Authenticated Key Management (AKM) for the Cisco Unified Wireless IP Phone , several choices for both authentication and encryption can be set up on the access points with different SSIDs. When the Cisco Unified Wireless IP Phone attempts to authenticate, it chooses the access point that advertises the authentication and encryption scheme that the phone can support.
