PURPOSE:To automatically display opposite characteristic information by reading terminal characteristic information in a memory from the terminal identification signal of a communication start request message at the time of incoming so as to display it in a display unit. CONSTITUTION:A communication function included in a start request control signal which is received from a terminal 100 on a transmission-side through an exchange 700 is compared with a communication function to which the terminal 100 registered in a register part 240 can correspond. When both coincide, the arrival of the start request control signal is informed to the terminal 100 on the transmission-side, and a processing for setting a channel is executed. Then, the terminal identification signal of the terminal 100 on the transmission- side included in the start request control signal is stored in an identification information register part 250. Next, the terminal identification signal is compared with respective terminal identification signals registered in the memory 810. When there is coincident one, terminal characteristic information corresponding to the terminal identification signal is displayed in the display unit 820.
