Alex, Pan, Daniel,...
Could this group => group:BUNDLE audio video in Message Body have anything to do with my Kamailio Video issue.

Thank you!!

Hi Alex,
No, I'm not using rtpengine.  It must definitely be some sort of Codec issue though, since I can seem to move the problem around and actually finally get video on the  softphone.  It was a little strange that I lost Audio on the WebRTC client though, since I only disabled VP8.

Since Kamailio is only relaying I am so confused why introducing Kamailio is messing up Video.

Thank you,
-Steve

Unless you're using rtpengine, you're just moving the problem around. Kamailio does nothing with SDP unless by way of rtpengine or told in some other way, such as sdpops.
