> 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.
