If the RGR05 works but does not ring the house phone, I suspect that something on the Comfort PCB is damaged. The RGR applies a high AC voltage to the phone to make it ring.You should hear a relay on the Comfort PCB clicking when the ringing signal is applied to the phone, to ensure that the ringing voltage is not poassed to the incoming telephone line. If the relay does not click, that part is probably faulty
