The phone is not a house phone. It was working fine and then just started acting up. All the programming looks exact to any other working phone. It is more like the phone does not know when you left up the reciver. So if it does not know that you pikced up the handset then it gives no dial tone. But it is NOT the phone becuase I does the same thing on any phone I hook up to the line. Could that be a bad wire in the run somewhere that may be disconnected or short?
