I have a remote location from the 3CX server that is connected via a VPN connection. At the remote location, I have a Patton 4960 with PRI. The hope was to have calls from the remote location use the PRI for outgoing calls so they didn't use the WAN connection for outgoing calls.
I've noticed that 3CX documentation states the Patton 4960 must be on the same subnet as 3CX. With the VPN in the middle, we are not, and really can't be on the same subnet. However, this network design seems ideal from a call perspective - keep the trunks local, use the pbx for call setup only.
Between the networks are Barracuda F100NG firewalls
Calls from UA's at the remote location are able to call out, and the calls go out the local Patton - however, the calls are anchored to the 3CX - so they effectively go across the VPN twice - once to 3CX and then 3CX back to the gateway before going out.
I'm not clear why 3CX is anchoring the call, and why the call is not setup as a ua-ua phone to gateway call.
I'd love to find someone who has done this successfully so I can do a stare and compare of the two configurations to see what I might be missing here. Or if anyone has suggestions as to what might be wrong with the general design and configuration, I would gladly take your suggestions.
