PURPOSE:To make a receiving party connect with a transmitting party by being able to bold and display a calling request displaying and transmitting party identification information through an exchange to a receiving side by the request from the transmitting party when the receiving party is busy, absent and does not respond to a calling from the caller. CONSTITUTION:When a receiving terminal SUB-B is in busy or absent and does not respond in a connecting condition, a calling request key A is pushed down and operated to register the calling request. Thus, into the calling request table of the receiving terminal SUB-B correspondence on a main memory device M, transmitting terminal SUB-A identification information (telephone number) generated from a calling request registerer, is stored. Further, when a message is issued from a transmitting terminal SUB-A, it is stored into a message registration area. By the receiving terminal SUB-B, it is found that a calling is requested from the flickering condition of a calling request displaying lamp B.
