I did disconnect tip and ring on all the speakers. Noise is still here, so it is on the power side. I did pull a isolated 120 volt circuit to the phone system and replaced power supplies. I'm thinking the issue lays between the punch down block and the speakers. But what????????????????????????? No motors, wires are high and tight. No nicks.
Think I am going to try what Bill suggested and ground all the unused pairs of the cat 5.
