ABSTRACT:
A door message apparatus has a control unit which responds to operation of a doorbell switch to connect a door speaker/microphone to an automatic telephone answering and recording machine. The control unit applies a ring signal to the answering machine so that the machine then plays back a prerecorded message which is broadcast to the door caller. After the playback, the door caller may talk into the door speaker/microphone to produce a message which is recorded by the answering machine.
