Installing dealer abandoned customer and he is having issues of phantom ringing on four Edge 120 phones with lights going on and phantom ringing but this is not happening with the older DX120 phones.

Also he thinks this problem started when a 4 CO card was added to the basic 8 cabinet.

Have you seen this before and could it be just the 4 CO card or just the phones?

I am NOT a Comdial guru, just trying to point him in the right direction.

Thanks, Bunnie
