I have updated my logging level from INFO to DEBUG, and I have also started a tshark trace with a circular buffer (tshark -b duration:1800 -b files:5 -w outfile.pcap), so I've always got two hours worth of packet capture.
Next time it happens, I should have more info to pass along. Mike Burden Lynk Systems, Inc e-mail: m...@lynk.com <mailto:m...@lynk.com> Phone: 616-532-4985 From: M.

The first time it happened, it was about 30 minutes into the call. It happened again today, about 5 minutes into the call.

My only thought at the moment is to run tshark all day, every day, possibly stopping and restarting it every hour or so, if no problem occurs to keep the output from getting out of control. You don't need to stop and restart. You can just delete logs and try again. If you should decide to do that, please read : http://sipx-wiki.calivia.com/index.php/SipXbridge_Overview_and_Configura tion#Problem_reporting I'll need logs. The 30 minute issue has something to do with session timer. Does your ITSP support session timers? The 5 minute issue could be anything at all.
