Abstract: An answering machine has a single tape for recording phone messages wherein messages are recorded on at least two tracks. The answering machine optionally includes a voice synthesis system for generating announcement messages and a microphone for recording announcement messages and monitoring audio events either over a phone line or via a recording. Recordings on each track are executed in the same direction. In one embodiment of the invention, a first track accepts messages received without requiring that a code be transmitted. Messages are recorded on a second track in a mailbox mode of operation only when a predetermined mailbox code is received. A second embodiment includes inputs for two phone lines. The first tape track is dedicated to a first phone while the second track is dedicated to the second phone line. A third embodiment further includes the capability to record on third and fourth tracks which function as mailbox tracks for respective ones of the first and second tracks.
