We have a remote user with a i5343 set connected back to an OS7100.

The user is connected via WiFi on the remote side of their network and all calling features work fine except for the Video Call mode which we don't get any video.

My guess is it's a port issue but I'm not sure which ones to open. As of now we have 6000 & 9000 UDP/TCP open and the MGI Channels forwarded only
