My wife bought a 2nd hand phone that is made to look like an old oak wall phone. After looking around the net, I believe the guts are actually a 79 we554. The issue is the ringer does not ring. I do not know that much about electronics, but I did check the voltage at the block where the green and red lines come in and it reads 56 volts when it rings. There is no visible damage to the ringer coil etc, so I am not sure if it is bad or from what I have read, Verizon fios may not supply enough power to make it ring? I disconnected all the other phones, but nothing. Any help would be greatly appreciated!
