PURPOSE:To make it possible that a called subscriber selects whetehr call is accepted or not by providing a voice file, where information to discriminate subscribers is stored, in an exchange and retrieving calling subscriber discrimination information by call and reporting calling subscriber information to the called subscriber with voice at the incoming time.

When exchange 2 receives and decodes the selection number from calling subscriber's telephone set SUB''A'' and connects called subsriber's telephone set SUB''B'' to message trunk 4 and the called subscriber answers, the position of the exchange and the name of the calling subscriber from voice file 5 are sent to the called subscriber with voice from message trunk 4 on a basis of calling subscriber discrimination information which has been already obtained, and the called subscriber selects call rejection or call acceptance by loop disconnection or not; and in case of loop disconnection, busy tone is sent to calling subscriber's telephone set SUB''A''
