Options

The Sonic Ring Elite Deluxe Videophone Signaler And Transmitter has three easy-to-use telephone ring signalers. All three telephone signalers install simply by plugging into an electrical outlet and a modular telephone jack. When the phone rings, a light plugged into the signaler will flash to alert you. Only one telephone signaler is required in a home, even if you have many telephone jacks. With a Sonic Alert telephone signaler, you will never have to miss another phone call again.
