My question is simple, on the Protel board for WE housings with a mechanical ringer, can the ringer be turned on and off with the Expressnet software or is it a hardware only option? I have a phone with a ringer that does not work, the fuses are good and nothing on the pc boards seems burned. The ringer does not ring. Before I spend an hour of my life tracing the board any ideas?
