Removing a WLAN IP Telephony Manager 2245 from the system
When a WLAN IP Telephony Manager 2245 is removed from the system,
wireless handsets using the WLAN IP Telephony Manager 2245 are
affected. If the removal of the WLAN IP Telephony Manager 2245 is
intentional, lock and idle it before removing the WLAN IP Telephony
Manager 2245.
When a WLAN IP Telephony Manager 2245 is removed from the system,
the removal is detected within two seconds. Wireless handsets not in calls
are immediately forced to check out and check in again.
Wireless handset scenarios
For wireless handsets on active calls, two possible scenarios can occur:
•
If the removed WLAN IP Telephony Manager 2245 provided the
gateway function for the wireless handset, the call is lost and the
wireless handset is forced to check in again.
•
If the removed WLAN IP Telephony Manager 2245 provided the timing
function for the call, the call switches to another WLAN IP Telephony
Manager 2245 to provide the timing function.
ATTENTION
During the two seconds while the loss of the WLAN IP Telephony Manager 2245
is being detected, the audio for the call is lost.
