Abstract
A multiple dwelling house interphone system includes a collective entrance machine, a dwelling room master device, and a management master device. The management master device is installed in a manager room to speak with the visitor or the dweller. The multiple dwelling house interphone system has a reception mode in which a call to any dwelling unit from the collective entrance machine is uniformly transmitted to the management master device. The management master device includes a forwarding button and a forwarding control section. The forwarding button re-forwards a call in the reception mode to an original calling destination. The forwarding control section re-forwards the call to the dwelling room master device of a dwelling unit as the original calling destination when the forwarding button is operated when a speech path is formed with the collective entrance machine in response to the call forwarded in the reception mode.
