I have two Mitel PBX’s, each with a PRI. I have the SIP account set up in the GXW4501. I’m having the same problem with both. You can call into the DID and the call goes to the PBX’s just fine. You can’t call out at all. The PRI is synced to the digital port on the GXW4501 just fine. My inbound routes for both the SIP and Digital Ports are the same:
_x.
_+x.
My outbound route for the SIP is:
_x.
_+x.
My Outbound route for the PRI is:
_XXXXXXXXXX (Where this is the DID as assigned by my SIP Provider, the actual 10-Digit DID and not X’s)
I have tried every Outbound route I can think of and it still doesn’t work. I even attached an ISDN Tester to the Digital port (thus bypassing the PBX) and same results. You can call in, but not out.
My SIP Provider is Momentum Telecom. They don’t show any attempt on Outbound calls and the error message is being generated by the GXW4501.
I am at my wits end. I know it’s got to be something simple, but darned if I can see it at this point.
