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.
Important:
During the two seconds while the loss of the WLAN IP Telephony Manager 2245 is being
detected, the audio for the call is lost.

Changing the master WLAN IP Telephony Manager 2245

If the master WLAN IP Telephony Manager 2245 loses communication with the network, the
wireless telephone system fails. All WLAN IP Telephony Manager 2245 units lock. All calls are
lost and no calls can be placed.
Therefore, if the master WLAN IP Telephony Manager 2245 must be replaced, ensure the
system can be shut down with minimal call interruption. Reset all WLAN IP Telephony Manager
2245 units after the master is replaced. If the IP address of the master WLAN IP Telephony
Manager 2245 is changed, the new IP address must be reconfigured in all WLAN IP Telephony
Manager 2245 units using that master.
