With this DoorBell Fon pack, you’ll be able to answer the door simply by picking up the phone. When a visitor presses the doorbell, the system will ring the phone with a distinctive tone (or give you a caller waiting tone if you’re already on the phone). The really cool thing is if you add the optional electronic door kit, you’ll be able to open the door by pressing the * key on the handset. Ooooh…automation. $132.00.
When a visitor presses the button on the door intercom, the DoorBell Fon rings the phones in your home with a distinctive ring. Pick up the phone to converse with the door. If you are on the phone when a visitor arrives a call waiting tone will sound to alert you. In fact, the DoorBell Fon system will even work without phone service. The system provides the necessary voltage to operate on its own.
