PROBLEM TO BE SOLVED: To evade a case where the service such as the guidance of absence or the transfer of an incoming message is carried out, based on the will of the call originating side. SOLUTION: A calling subscriber transmits additionally a special number to the number of a telephone set 5 by means of a telephone set 1 to inhibit the service such as the guidance of absence or the transfer of the incoming message.
