PROBLEM TO BE SOLVED: To provide a facsimile system utilizing a PSTN line that can automatically transmit a message to a telephone number after revision when a transmitter side facsimile terminal transmits the message to a telephone number of a receiver side facsimile terminal before revision even if the telephone number is revised. SOLUTION: When a facsimile terminal makes facsimile transmission with a number before revision to a possessor of a line whose number is revised, an exchange informs the facsimile terminal about the number after revision by means of a voice message or a DTMF signal. The facsimile terminal detects the informed voice message or DTMF signal denoting the number after revision, stores it, and makes redial to the number after revision after interrupting a line.
