B.H.

Hello, all.


We have noticed many calls on our PBX get "stuck" - the other end sends BYE, and our side sends ACK but the call remains active (no hangup event on AMI, the call is listed in 'core show channels') and it's impossible to hang up until asterisk is restarted. Asterisk's log shows lots of messages like this:


chan_sip.c: Autodestruct on dialog .... with owner SIP/.... in place ...


All the mentioned channels were stuck on the same dialplan line which reads like this:


Set(meetme_act=${CONFBRIDGE_INFO(marked,${MeetMeNumber})})



Actually, trying to check the number of admins in a ConfBridge's room (to see if the room is active).


After removing the above line (and restarting asterisk) - the problem disappeared. So my conclusion is that this is probably some kind of a deadlock with CONFBRIDGE_INFO function. I've tried to look for bug reports, but didn't find anything similar. Is this a known issue?


We're using Asterisk 11.9.


Best regards
