"I tried adding this line to vars.xml: (<param name="renegotiate-codec-on-reinvite" value="true”/>" This would be because its not a variable, its a sofia profile param that you would add to a profile thats in the sip_profiles directory.

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:
