Random hangups during calls

Asterisk Asterisk Support
1

We’re suffering from an issue whereby calls randomly hangup, or terminate. This happens on incoming and outgoing calls, sometimes during a call, sometimes when being transferred. There’s no pattern I can see, but it appears to be getting worse with 2 reports last week and about 10 so far this week.

Other than the random hanging up, calls are working normally and sound great.

The asterisk server is running 1.8.

Here’s a log file of just one call. It looks like one of the parties initiated a hangup as normal, but neither party did. These looks the same as the other log examples I have here.

Any ideas what the problem might be? I’m trying to get a packet capture of one of the calls but it’s so random, and we have so many handsets, that it might be hard.

Are you using a WebGUI like FreePBX to generate your Asterisk DialPlan?

To be totally honest, I can not make any good sense of the logs. The safest bet to debug this would be to do a packet capture.

HI

Yes we do use Freepbx. Is it likely to be a dialplan issue though if the calls are already dialed and connected?

I’m doing a packet capture now but as the problem is random , and we have a number of handset (150+) the capture is massssssive.

Olly

I see that you have quite a busy PBX. And debugging a FreePBX dialplan in a nightmare by itself. So it will be hard to find the exact cause of the problem.

I would suggest sticking to a packet capture and trying to catch the problem there.

5

If the pbx is busy and you are using freepbx , then adjust your logger.conf so that it doesn’t log verbose, on a busy system the logging can cause this issue, also if you are recording this also may cause issues.

details and short video on tracing is in my sig. by just capturing the messaging and not the rtp you can leave it running for some time.

Thanks Ian

I’m going to watch your videos as I think they will be very useful to me. In the meantime here’s the plain text output from a packet capture for a short outgoing call that had this issue this morning. I’m not sure this is the correct format for posting here, but here goes.

Also, Freepbx advise not to change any .conf files that don’t have CUSTOM in the name, and that one doesn’t. However the Asterisk Log screen in Freepbx was set to log verbose and debug to the full log file.

I’ve changed disable both debug and verbose on the Full log, and left them on at the console log (though we don’t use the console logging day to day).

Thanks for the tip. I’ll see whether this helps.

Just realised that that packet trace is the wrong one !!!

Apologies.

Here’s the right one.
