Abstract
A voice frequency response system comprising a subscriber's terminal unit including both a functional part functioning as a telephone and a functional part functioning as a facsimile receiver, a voice frequency response device including a functional part functioning as a facsimile response unit, and a telephone line connected between the terminal unit and the voice frequency response device. The voice frequency response device comprises a voice frequency response unit transmitting a required message to the telephone in response to a demand for voice frequency response service from the telephone in the terminal unit, and a facsimile response unit transmitting necessary information in the message or other information including the necessary information to the facsimile receiver in the terminal unit. Therefore, the subscriber is freed from the cumbersome effort of writing the message, and the possibility of mishearing or miswriting leading to a future trouble can also be eliminated, thereby improving the serviceability and reliability of the system.
