The door-phone box of the present design may be used as installed, for example, on a wall at a building entrance or the like in combination with a multifunctional telephone set, so that a manual pressing of the operating button will produce at the telephone set a chime sound of a visitor's calling and a conversation may be made between the door-phone box in the exterior and the telephone set in the interior of a building.
