TITLE CENTRALLY LOCATED AUTOMATIC ANSWERING AND RECORDING EQUIPMENT A telephone answering and recording system designed for installation in a centralized location remote from the customer's premises. A single line is employed in normal operation between the customer's telephone equipment and the centrally located answering and recording equipment. The answering and recording equipment may be located in a telephone central office or alternately in a separate location remote to both the customer's equipment and the telephone central office. When the equipment is in operation providing answering service, the customer's own phone line is isolated from the telephone central office. If the customer goes "off-hook" the answering equipment is dropped and the customer's line is automatically connected to the incoming call.
