Connect to the WLAN IP Telephony Manager 2245 101the entire WLAN IP Telephony Manager 2245 group fails. All active callsare lost and no future calls can be placed until the master WLAN IPTelephony Manager 2245 is replaced (either by installing a spare or byreconfiguring one of the slaves to be a master).• Alternately, if one of the slave WLAN IP Telephony Manager 2245s fails,the group as a whole still functions, although some individual callscan be lost due to the reassigning of handsets throughout the group.One less WLAN IP Telephony Manager 2245 also means that the callcapacity of that node is lost until the failed WLAN IP Telephony Manager2245 is replaced.A keep-alive packet exchange runs between the wireless handset andthe WLAN IP Telephony Manager 2245 every 30 seconds. If the wirelesshandset detects that the WLAN IP Telephony Manager 2245 is unreachable,the wireless handset resets itself and attempts to reestablish a connectionwith the master WLAN IP Telephony Manager 2245.Configuration tasksThe following are the tasks required to configure the WLAN IP TelephonyManager 2245:1.
