Strange one this. I am interested in converting an old dial telephone to ring when a proximity sensor is triggered and play a recorded message when the receiver is picked up. I need a way to turn it off when I don't want it, and ideally, it needs to run from a battery power source (not essential). The idea is it sits on a shelf and when someone comes into the room, it rings when a motion sensor is triggered. I need the ability to change the message. Like magic!
