I am a dms500 tech that is having configuration problems with a customer running a iwatsu adix pri. We are configured as compliant NI2 and inbound calls process just fine. The customer states that he has mapped the individual buttons on his phone. He claims that we are providing dialtone on these buttons. Looking through my tables we are not serving dialtone on the b channels and I never see him connect to a trunk. I am also seeing no inbound messaging when he says that he has dialed a call. the inbound calls demonstrate that the pri is communicating with the correct protocol. I would appreciate any information that could be provided. Thanks
