An apparatus for providing remote answering of a doorbell includes a circuit for receiving a doorbell signal indicative that a doorbell switch has been actuated. An autodialing circuit is coupled to and responsive to the receiving circuit and a telephone line for dialing a telephone number responsive to the doorbell signal. An alerting circuit generates an alert signal to be transmitted over the telephone line to the telephone number dialed by the autodialing circuit, so that the alert signal may alert a party answering the remote telephone to the fact that the party is responding to a doorbell rather than a normal telephone call. An audio speaker is physically situated near the doorbell switch, for reproducing audio signals from the telephone line which are generated at the remote telephone. An audio microphone is also physically situated near the doorbell switch, for generating electrical signals responsive to sounds made near the doorbell switch and transmitting the signals to the telephone line to the remote telephone. The apparatus further includes a switching network for coupling the door speaker and microphone to a local telephone set and a remote telephone set selectively in any combination.
