It happened a few times now, our customers stop making/receiving calls because the call is not terminated properly on asterisk, and the call limit is 1.
Restarting the ATA (linksys pap) does not help, the call is still there in >core show channels.
hanging up the call (>hangup SIP/xxxxxxx) solves the problem, but we need to wait for the customer to complain to know that the call is kind a zombie in the system.
Is there any setting to automatically force the call to terminate if there is no traffic, or some other trigger to shut the call down in the system in this type of situation?
Is this a bug? It seems to happen when the call is abruptly stopped, as if the power in the ATA went down during the call.
Thanks
