I have the same issue as the OP. SP1 set to GV, SP2 to Callcentric. The Callcentric shows as "Registered" on the OBiTalk configuration page. But the phone connected to new Obi 100 does not ring when someone calls the Callcentric number, and the caller gets a "Welcome to Callcentrix, the person you are trying to reach is not available" recording. I can call out via Callcentric. By dialing **2 then 17771234567 I get the Callcentric test service.
Why no incoming Callcentric calls, what could be wrong?
Thanks,
b
