[asterisk-users] Channels freeze on Confbridge

[Carlos Chavez]

     I am having a strange problem.  We have an Asterisk 16.12.0 server 
(we have upgraded at least two versions since we found the problem) 
where users complain that confbridge calls end after about 30 minutes or 
so.  The problem is that according to Asterisk the calls are still 
active.  All users are cut off at the same time but a "core show 
channels verbose" still shows channels as active:

I have to manually hangup the channels.  The PSTN provider is a SIP trunk.
