Upon further investigation, I have observed that FS is always changing the Video port while keeping the audio port same in SDP updates. Probably this is the reason the video is lost after the 2nd switch from audio to video. and Eventually, the new offered video ports does not opens at system level (netstate -ntulp) and older ports can bee seen bound by Freeswitch, but a tcpdump on those new ports does show rtp data flowing. Is that the normal behaviour? if not, what could be the reason FS changing video ports in each new session. I am on Proxy mode. Looking forward.
