Abstract: A telephone answering machine adapted for use in conjunction with a telephone system having a station-to-station call transfer capability for incoming calls includes a tape deck and various components for recording and playing back announcements and messages under microprocessor control. The answering machine also includes a DTMF receiver and DTMF generator for receiving and sending digit tone signals. The microprocessor directs the operation of the answering machine for recording data from a calling party, which data represent a telephone number to which the calling party wishes to be transferred. Thereafter, the microprocessor directs the operation of the answering machine for dialing this telephone number after a hook flash has been used to request a call transfer sequence by the telephone system. The telephone answering machine thereby enables call transfers to take place upon the initiative of calling parties.
