I have a Polycom VSX 8000 and a client we are trying to video conference with are having an issue. We can both hear audio just fine G.711, and when it comes to video they can see me, but I can't see them. I just see a blank screen on my Polycom VSX 8000.
First thing that came to mind is firewall issues. Making a couple day story short, I opened all ports to a spare public IP address that pointed to my Polycom VSX 8000 and I am still not able to see their video feed. We have a FortiGate 310B and is H.323 compliant. Any ideas? I'm trying to make sure I am not missing anything here. Thx!
