I have call manager 7.1.3, MGCP voice gateway 2921 & ip phone 7911 & 6921.
I have observed that when IP phone A calls to IP phone B or any PSTN number. During the call if IP phone A will get power off, then also opposite phone will still remain connected undefined period of time. This call will disconnect only if opposite user will disconnect the call manually.
IP phone A calls to IP phone B. During the call if LAN cable of the IP phone A will get disconnect, still on both phones it will show connected. After some time on IP phone A it will show connected with meassage "Features disable".
This behaviour i have observed with CUCM version 4.1, 6.1, 7.1.3.
Is this the default behaviour of all CUCM ?
