a collective entrance machine installed at an entrance for a visitor to call a dweller;
a dwelling room master device installed in each dwelling unit for responding to the call from the visitor by the dweller; and
a management master device installed in a manager room to speak with the visitor or the dweller, wherein 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, and
the management master device includes:
a forwarding button that re-forwards a call in the reception mode to an original calling destination; and
a forwarding control section that 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 in a state where a speech path is formed with the collective entrance machine in response to the call forwarded in the reception mode,
wherein the collective entrance machine includes a collective entrance machine display section that displays a calling destination,
wherein, in the state where the call from the collective entrance machine is forwarded to the management master device, the collective entrance machine display section displays that the call is forwarded to the management master device, and
wherein when the call is re-forwarded from the management master device to the original calling destination, dwelling unit information of the original calling destination is displayed.
