Adding a WLAN IP Telephony Manager 2245 to the system
When a WLAN IP Telephony Manager 2245 is added to the system, the change is seamless
and does not affect wireless handset calling ability.
A new WLAN IP Telephony Manager 2245 is detected within two seconds of being added to
the system (booted, configured, and connected). When detected, any wireless handset not on
an active call is immediately forced to check out and check in again. Any wireless handset in
a call immediately switches to the WLAN IP Telephony Manager 2245 assigned to provide its
timing function. This switchover is not usually noticeable to the user because it is similar to a
normal handoff between APs. When the wireless handset ends the call, it is forced to check
out and check in again.

Checking in to the Gateway

When a wireless handset is checking in with the WLAN IP Telephony Manager that is providing
the Gateway function (not necessarily the same WLAN IP Telephony Manager 2245 that is
providing the timing function), the wireless handset is assigned its Alias IP address.
Subsequently when the wireless handset checks in with the LTPS, the wireless handset
identifies itself with its new Alias IP address to the Call Server. If the wireless handset is
checking in again and again, it can indicate a problem on the network, such as poor AP
coverage for a user who is moving about. This information is useful when troubleshooting.
