Problem connecting to Polycom MGC with new HDX 8000 & 9000. No video from far end.

Asked by InfoSysNetworks in Telecommunications, Voice Over IP, Networking Hardware

Tags: Polycom 8000, Polycom 9000, Polycom MGC

I have two new Polycom boxes (HDX 8000 & 9000). I can connect to multiple locations with no problem, but when I try to connect to a Polycom MGC at another site I don't get far end video or sound. I am prompted to enter my conference code, but never get the following video or sound. The other side says they see/hear me sometimes.

If I pull the 8000 or 9000 out and replace it with an older VSX7000E (using same IP), I can connect to the MGC with no problem. As I mentioned, the 8000 & 9000 can connect to other 8000s, etc, just no to the MGC.

I am running 2.5.0.6-3955 on the 8000 & 9000.

There is no router between the boxes and the internet router. The router is not blocking any ports and I am NATing the boxes. But as I mentioned, I can connect to other locations, so I don't think I have a network issue.

Any one seen this or have any ideas?
