I'm trying to get a Callcentric SIP trunk to work with 3CX, but am having some problems. The 3CX server is inside my network and communicates through a Forefront TMG server out to the internet. I've installed the 3CX softphone on the PBX server and configured it for my Callcentric account and I am able to successfully make outbound calls and receive incoming calls, so the TMG firewall seems to be passing traffic okay.
I used the Callcentric template when adding the VoIP provider, and I can successfully receive incoming calls. However, when I dial an outbound call, I see this in the logs:
The outbound rule is set that prefix 5 dials via the VoIP provider and strips the 5, and I am dialing an 11 digit US phone number (which works fine when testing with the 3CX softphone). Are there any suggestions where I might look to start debugging this?
