I have a customer that has intermittent issues on the first TRaP port
(port 40) in a Nortel Option 81C digital PIMG integration to Unity 5.0(1). The PIMG makes the call to the phone, the person answers, and all they hear is static. The port just has to be unplugged and plugged back in to reset it and then it will work again for about
another month. This is pretty unacceptable to them, as you might imagine, since Unity doesn't see this as a failed call and continues to use this port for TRaP calls. We disabled the TRaP ports on this PIMG unit (PIMG5) and ran off PIMG4 (next up in the stack) for awhile and the same thing happened, so it is not localized to just PIMG5.
Does anyone have any feedback regarding:
1) What are the recommened PIMG traces (I would imaging Tel and VoIP) and Unity traces that I need to enable when the problem reoccurs in order for TAC to find some answers.
2) The recommended PIMG code release?
3) Similar issues? Possible solutions?
