Problem Details
If we loop a Innovaphone PBX behind a Nortel PBX, we have often a problem with no way audio channel. The problem is that the Nortel PBX used the timeslot 16 with the Channel 31. The Timeslot 16 is for the signalling in the QSIG Protocol. Innovaphone use the Timeslot 16 with the channel 17 for the signalling.
