PURPOSE: A call duplication method of a home network system is provided to supply a call service between household terminals even if malfunction occurs in a SIP(Session Initiation Protocol) server or a common unit. CONSTITUTION: A call request terminal performs a call request to a receiving terminal(S300). A normal condition of a session initiation protocol server is determined(S400). In case the session initiation protocol server normally operates, the call is performed between a call request terminal and a receiving station by using the session initiation protocol server(S500). In case one or more happens in the session initiation protocol server, the call operates between the call request terminal and accepting station by using the integration server(S600).
