The method employs signal flow switches (4,5) for classifying the numbers from an facsimile keypad (3) into a row data and column data, a signal flow control unit (8) for controlling the flowing and blocking of the signals, and an interface driver (6) for preventing the collision between the signals to maintain an unidirectional signal flow, and receiving the telephone number by the said control unit to dial the telephone number with a dialler (1), thereby dialling a telephone number by using a facsimile keypad.
