We've got an 'proper' bell connected up to phone wiring (was here when we moved in). house is a bit rambling and the it's useful because don't always here the phone ring if not near a handset.
a while back it took to 'dinging' every so often (say every 15-30 mins?), which I stopped by putting some folded tissue in to deaden the ring (as it was annoying). but we miss it.
anyone know whhy it might have started doing it and how I could stop it.
