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.
