Abstract

See full text

A telephone answering system in which the calling party may record a message of any length within the recording capabilities of the message tape, and is not limited to any predetermined message time interval. The system is controlled by a microcomputer, and includes circuitry such that the microcomputer only responds to actual voice signals, so that the message recording interval is terminated when the calling party stops talking for a particular time interval, regardless of whether a tone signal or a busy signal then appears on the telephone line.
