-------------------------------------

    Assignee: Joeran Vinzens
      Status: Waiting for Feedback  (was: Triage)

Hi Joeran,  We're taking another stab at trying to reproduce this and have just have a few more questions...

Can you attach the asterisk.conf and rtp.conf files?

I'm assuming that, since the incoming call lasted 20 minutes, that audio was flowing in both directions, yes?  On the outgoing side, did the loop ever stop or did it just continue until the call ended?  I can't tell from the pcap because it only shows the first 15 seconds or so.

Thanks.

> Fom time to time we can see traffic increase on out Asterisk Systems. After some debugging we see the Asterisk send kind of an Invite loop over and over. Since there is no way to deny re-invites in PJSIP there is no way out of it. From asterisk perspective it sends these re-invites as fast as it can which result in an increase of 3MBit/s of signalling traffic from this maschine. So far we do not know how to reproduce the issue but we captured the scenario from our production system. (trace attached) the Asterisk log itself just tells us the Invite is going out but nothing further. There was no trigger on the other call-leg.
