From time to time, I have to manually kill some “frozen” calls with soft hangup commands in my Asterisk PBX phone system.

(As far as I can tell, those freezes occurred after network breakdown (VPN or ethernet link between 2 LAN switches). So at this point, I would say I can’t do much to keep those network breakdown to happen).

So, which tools are available to automatically detect that SIP channels are up without but no RTP media is flowing in or from them ?

Regards
