The parent device voice processing unit 207 is activated by the control of the parent device microphone 201 and the parent device speaker 202, the parent device voice processing unit 207, the parent device I / F 210, the transmission path L, and the child device I / F 106 of the child device 1. A communication path is formed between the handset microphone 102 and the handset speaker 103 via the handset voice processing unit 105, and a voice (transmitted voice, received voice) signal is transmitted via the formed communication path. By transmitting and receiving, a call is established between a resident who has performed a response operation using the parent device operation unit 203 of the parent device 2 and a visitor.

  On the other hand, if a response operation is performed using the terminal operation unit 303 of the wireless terminal 3 before the response operation is performed in the base unit operation unit 203 of the base unit 2 shown in FIGS.
