Hi, I am trying to get my client to work with Freeswitch in the following context to no avail. If I initiate a video call, the video works fine. However, if I start an audio call and then try to add video later in the call, no video is received. I tried adding this line to vars.xml: (<param name="renegotiate-codec-on-reinvite" value="true”/> That, however, did not fix the problem. Any help would be greatly appreciated. The SDP negotiation is indicated below. Thanks in advance. I do see in fs_cli that FS has received a new SDP and is trying to renegotiate as follows: INITIAL SDP (AUDIO ONLY): v=0 o=FreeSWITCH 1421171138 1421171140 IN IP4 146.148.54.28 s=FreeSWITCH c=IN IP4 146.148.54.28 t=0 0 m=audio 25746 RTP/AVP 124 101 a=rtpmap:124 opus/48000/2 a=fmtp:124 useinbandfec=1 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=silenceSupp:off - - - - a=ptime:20 a=sendrecv m=video 26852 RTP/AVP 98 a=rtpmap:98 VP8/90000 NEW SDP WITH ATTEMPT TO ADD VIDEO TO EXISTING SESSIOn: 2015-01-14 00:55:29.401667 [DEBUG] sofia.c:5828 Remote SDP: v=0 o=1000 3968 2153 IN IP4 10.1.10.10 s=Talk c=IN IP4 10.1.10.10 b=AS:380 t=0 0 a=rtcp-xr:rcvr-rtt=all:10000 stat-summary=loss,dup,jitt,TTL voip-metrics m=audio 53368 RTP/AVP 124 101 a=rtpmap:124 opus/48000/2 a=fmtp:124 useinbandfec=1; stereo=0; sprop-stereo=0 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 m=video 9078 RTP/AVP 103 a=rtpmap:103 VP8/90000
