ABSTRACT:
An automated telephone answering system with plug-in tone responsive unit at each of a plurality of extensions, a central answering unit responds to a caller initiated, telephone company generated, ring signal on the telephone line and establishes a connection with the calling phone. Each of the remote units responds to a different predetermined, selectable tone frequency. When the caller pushes a key on a standard Touch Tone phone key pad to select a specific extension, the responding remote unit generates a ringing signal for that extension. If the telephone line has an on-hook status, the system has means that prevents response to further tone signals.
