[SR-Users] No Video between WebRTC Client and Softphone when using Kamailio...works without Kamailio

[Wilkins, Steve]

I just did a test where I disabled VP8 in Kamailio using SDPOPS and I now get Video on the softphone however, I lost two-way Audio.  Kamailio seems to be  doing something with the codecs but still can't put my finger on it.  The WebRTC Client, who is the caller, needs VP8 for Video, and apparently Audio.

I'm not sure if I getting closer or just moving the problem around.

Thanks All!

I am desperately trying to resolve a big issue I have when using Kamailio 5.2.0 and Asterisk 15.3.

As soon as I go through Kamailio, I get no Video on either side of the call; I do get two-way audio and the call stays connected.  If I simply go right through Asterisk, I also get two-way Video.  I am having a tough time determining why Kamailio is messing with the Video portion of the call.
I have included a full pcap file.  As a side note when comparing pcap traces of the Non Proxied vs Proxied call, the INVITE and 200 OK from Asterisk and Softphone are exactly the same.

Thank you,
-Steve
