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
