A VoIP interface device providing a telephone service through Internet is provided to enable a user to more easily use the Internet telephone service by using an existing home telephone network and a general telephone. A general telephone interface(310) is connected to a home telephone network. An Internet interface(340) is connected to the Internet. A signal converter(320) converts a dialing signal or a voce signal into an analog or digital signal. A VoIP(Voice over Internet Protocol) packet assembling/disassembling unit(330) assembles the dialing signal or the voice signal, converted into the digital signal by the signal converter, into a VoIP packet and disassembles the VoIP packet inputted from the Internet interface into the dialing signal or the voice signal. If plural telephone lines are used, a plurality of the general telephone interfaces, the signal converters and the VoIP packet assembling/disassembling units are present. A setup controller sets mapping of each general telephone interface, signal converter and VoIP packet assembling/disassembling unit according to a corresponding telephone line, or changes the set mapping and enables a user or a service provider to control setup through Internet.
