Abstract
A magnetic tape type of telephone answering system is provided which is capable of being operated from a remote point. 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 the tone, the telephone answering system automatically rewinds the message tape to its origin position, and then plays back all the accumulated messages recorded in the message tape and causes the recorded messages to be transitted to the calling party over the telephone line. The message tape is stopped after the transmission of the last message by the person sending the tone a second time over the telephone line, and the telephone answering system is thereby again set to its normal telephone answering operational mode.
