Olivier Lambert updated ASTERISK-21411:
---------------------------------------

    Assignee: Michael L. Young  (was: Olivier Lambert)
      Status: Triage  (was: Waiting for Feedback)

I have uploaded an archive containing the pcaps and asterisk debug info of test session made on asterisk 1.4 and 1.8. The archive also contains the sip.conf and a small drawing of the architecture used for the test...

To complete the info about the tests, in ast1.8 pcap, you can see an RTP flow starting at frame 2605. At frame 5210, the reinvite should stop the previous flow and send it elsewhere but by looking at duration of RTP flow (25,640 sec)  we see that it is not interrupted at all (causing the one way from user perspective)

Looking at the same sequence in ast1.4 pcap, you see that the RTP flow starting at frame 2783 last for only 14,759 sec; this time stamp correspond to the reinvite initiated by frame 5143. This re-invite is also causing the transmission of RTP flow starting at frame 5186…

Thanks

> A re-invite without SDP is causing the voice to be established in one way. The exact same test done on asterisk 1.4.38 is not giving the issue, creating a two ways audio as it should. Pcaps of the two tests are available at http://www.misterlambert.net/pcaps.zip. Reinvite is located at frame 5127 for the 1.4 test while it is located at frame 7897 for the 1.8. The one way audio is caused by the missing RTP flow visible at frame 5166.
