It is to provide sex. The present invention as described above is a closed circuit selection means for selectively forming a closed circuit between the exchange device, the elevator and the terminal, and the first matching means for matching the voice signal transmitted from the exchange device by the selection of the closed circuit selection means to the elevator car side. And filtering means for filtering the voice signal transmitted from the elevator car, and adjusting the sensitivity of the voice signal obtained from the first matching means to send it to the elevator car and phase modulate the voice signal obtained by the filtering means. Phase modulating means for synthesizing a voice signal of the voice signal; amplifying means for amplifying and outputting a voice signal of an exchange apparatus obtained by adjusting the sensitivity of the phase modulating means; and a voice signal obtained by the voice amplifying means to match the elevator car. Note is achieved by being made up of a second matching means.
