I have 7931 with SCCP31.8-4-4S running on CME 12.4.22T1. From time to time user can't end the call by pressing "End Call" button or normally. The call stays in progress even the remote party hung up already. Only the way to end this is reboot the phone. sh ephone offhook shows 0 phones on call, but 7931 keeps blinking the line and show the call on the screen.
Did anybody see such thing?
