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

[Wilkins, Steve]

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.
