Abstract

A solid state telephone answering system is provided which includes replaceable magnetic tape cassettes, one of which contains a recorded announcement to be sent to the calling party when the system first answers the telephone, and a second of which serves to record the message from the calling party. A person may achieve remote control of the system by transmitting a tone of a predetermined frequency over the telephone line for a short time interval. In response to such a tone, the telephone answering system conditions itself to permit the caller to record a new announcement on a loop magnetic tape in the announcement cassette.
