are there any known reasons why Asterisk would disconnect random
calls ?
My server uses 1,5 GB out of 8 GB RAM
My server uses up to 35% CPU at peak
There are about 40 concurrent calls.
I have 300 RTP-ports available.
I just see the call ending, as if one of the connected parties hung
up but that is not the case !
So what could be a bottleneck ? Any known reasons for random hangup ?
Check that those calls are not sended to phones which are already
online, doesn't accept further calls, and your dialplan don't manage
this situation
Maybe I need to explain a bit further : the call is send to the
IP-phone and answered. The call lasts for about 1 à 2 minutes and is
then disconnected.
Sometimes this happens after about 1 minute, sometimes after about 2
minutes, sometimes it does not happen at all for a whole day or week !
If I say random, I really mean random.
I'd love to believe that there is some kind of bottleneck or level
that is reached when this happens, but nothing points to that direction.
We had this problem with some PSTN call termination providers,
sometimes only against some destination. I don't know if your
incoming calls are 100% VOIP, I would start to see with providers.
You may also check hangupcause and dialstatus variables.
Pure SIP.
Hangupcause 16
Dialstatus Answer
It has nothing to do with the provider-side.
Kind regards.
