WLAN Settings
We recommend that you set a separate SSID for the phone to connect.
However, if there is an existing SSID configured to support voice-capable Cisco Wireless LAN endpoints already, then
that WLAN can be utilized instead.
The SSID to be used by the phone can be configured to only apply to a certain 802.11 radio type (e.g. 802.11a only).
Enable WPA2 key management.
