I just inherited a customer with an Elite 192 (software version 5.3). An out of state dealer sent him replacement phones .... DTP-8D-1.

Somewhere in the back of my mind.... going back 7 years,... I sort of recall that DTU phones will work on the 192 and the IVS2000 PBX, but there was an issue with DTP phones (made for the PBX) being used on the 192.

The problem he is experiencing on the DTP's is that they work just fine for a while, then the handset goes out. The speaker phone works fine and all of the other features seem to work fine..... just the handset goes out.

If I swap the station with a DTU, it works just fine. I tried three Different DTP's and they each show the same problem.

Does anybody know for certain if there is a compatibility issue between the DTP phones and and Elite 192...version 5.3?
