I'm trying to setup a Polycom HDX 6000 in a remote office to connect to our ESI-200 in our HQ. The offices are connected via an MPLS and both networks can fully see each other. However, when I setup the HDX to mimic another Polycom that is within the same network as the ESI-200 it fails to register.
Diagnostic pings indicate that the IP is reachable but h.323 and SIP are not for some reason. Although that is true for both the HQ Polycom and the remote, but HQ registers just fine.
I'm not sure which device or network is causing a problem so I'm reaching out to all parties to see if anyone can explain why SIP won't work over MPLS.
If anyone has any suggestions please let me know.

Recieved word from ESI this morning with the following information.
All ESI Communication Servers (199, 200, 600 or 1000) do not support Remote SIP Stations; All SIP Phones are restricted to working locally at the MAC Layer in the Comm Server. SIP Phones must be on the same Subnet and Broadcast Domain as the phone system to work. Only the IP Server 900 will support Remote SIP Stations as the 900 supports registration.
So there is really nothing to be done about it, it is a limitation on our phone system not a communication issue with the Polycom. Thanks anyway.
