PURPOSE:To easily connect with an audio conference by analyzing the telephone numbers of conference members transmitted from a caller by a push-phone dial reception circuit, storing them in a memory and automatically transmitting the stored telephone numbers. CONSTITUTION:When the calling command of an audio conference and the subsequent dial numbers of conference members are inputted from a caller by a pushing signal, the dial numbers are successively analyzed in a push-phone dial reception circuit PBREC 5 and are stored in a memory 6 via a CPU 8. Afterwards, by synchronizing with the termination of the reception of the dial numbers of the conference members, the dial numbers stored in the memory 6 are read. The dial numbers are transmitted via an idle line circuit monitored by the CPU 8, for instance, a response/dial transmission circuit 2-N corresponding to a line circuit 1-N and the connection with the conference members is completed. In a display 7, the dial number and a conference time in each line circuit based on the detection of an incoming signal is displayed. |
