[Freeswitch-users] Adding video to audio call

Hi, I am using Freeswitch version 1.9.0. I can make video calls. But when I try to add video to audio call it does not work. A makes audio call to B. Call is established. A adds video . ReINVITE sent to freeswitch has video added in SDP.Freeswitch sends 200 OK response for this INVITE to A which has video in SDP. But there is no ReINVITE being sent to B. I tried enabling renegotiate-codec-on-reinvite in vars.xml and also internal.xml Is this supported? If so is some other configuration required. Regards,
