Axxess 256, 8.224. Music coming off cpc works on hold. Music coming off OPC card produces squeals, electrical noise, dead air, or sometimes the music its supposed to play on hold. I set a phone up for testing with acd where I dial in and I set the hold music for this hunt group to come off the opc card. The trunk group is set for Next audio device.
I have swapped the cords to the radios, and the radio's but the electrical squeal I get doesn't care whether I have the cord plugged in or not.
The lines are incoming off a pri no copper. I swap out the opc card same problem. Inter-tel says it must be something with the cpc. Load a new one with 8.224, transfered the license, saved their database and loaded it onto the new cpc, same problem.
