Door Bell Phones:

  • Rings phones in the home when door intercom button is pressed
  • Pick up the phone to converse with door intercom

    When a visitor presses the button on the door intercom, the Door Bell Phone 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 Door Bell Phone system will even work without phone service.
