Connection Problem with Polycom VSX7000

Not applicable

Hello All,

I am having issues with video conferencing when using our Polycom VSX7000 which was working fine previously with our Checkpoint Firewall. When we switch over to PA-2020. We start having issues.

We are able to dial out to connect with remote VC unit but when the remote VC units tried to connect to us, the VSX7000 shows connected but there is no video or audio.

The rules are allow any from external to internal as well.

We have another LifeSize unit which works just fine.

Both are NATed.

Are you using static NAT or dynamic NAT?

Does the Polycom use H.323?


Yes Benjamin

What will do in this case



It may or may not help, but it looks like our issues with the polycom VC systems, which were similar to yours, all went away with the update to the 4.1.3 code.

Set up with Static Bidirectional NAT  & simple application filter security rules.


Hi Nick
