At this time the security solutions available on the Cisco 7920 Wireless IP Phone are wired equivalent privacy (WEP) and LEAP (part of the 802.1X architecture).
For a wireless voice deployment, Cisco recommends the following security solutions:
Strong passwords and unique logins for wireless voice
Separation of data and voice VLANs
Separation between wireless voice usernames and passwords and wired equivalents
Cisco recommends that all wireless voice deployments eventually use LEAP. While it is common for new deployments to use static WEP in order to solve any installation problems before adding LEAP, static WEP should be used only during the installation period.
When a deployment begins to use LEAP, Cisco recommends using strong passwords, which contain a minimum of 10 characters comprising uppercase and lowercase letters as well as special characters such as *&%$#@?!. Strong passwords are generally not easy to enter into the phone and therefore are usually stored locally on the phone. These passwords are hidden and cannot be seen.
I have one more query, when we enable security on voice there may be some delay in reassociating with next AP. i.e. during user roaming from one AP to other user will not feel the delay in re-associating, re-authenticating etc.
