PURPOSE: An internet telephony service apparatus and method in a cable network by which an IP(Information Provider) is supported is provided to offer an internet telephony service apparatus and method in a cable network by which an IP is supported, so as to extensively apply telephone service, provided from a PSTN, to a cable telephony. CONSTITUTION: An internet telephony service apparatus is comprised of the first and second network segment parts(200,240), the first and second DIBs(Directory Information Bases)(218,264), the first and second ITGs(Internet Telephony Gateways)(220,262), the first and second PSTN phones(256,258), a WWW(World Wide Web)(252), Internet(254) and a PSTN(260). The first network segment part(200) comprises the first headend part(202), the first router(216), the first hub(204), a cable modem(206), the first and second cable phone(208,214), a cable fax(210), and a cable TV(212). The second network segment part(240) comprises the second headend part(242), the second router(250), the second hub(244), a cable modem(206), and the third and fourth cable phone(246,248). The first and second DIBs(218,264) store IP addresses corresponding to the telephone numbers of the cable phones(208,214,246,248). The first headend part(202), if the telephone number of the first cable phone(208) or the second cable phone(214) is inputted through the cable modem(206) and the first hub(204), reads the IP address stored in the first DIB(218). Then the first headend part(202) sets up a call path with the first cable phone(208) or the second cable phone(214), after determining an access voice session using an IP protocol from the read IP address. The routers(216,250) connect the network segment parts(200,240) each other or allows them to connect with the ITGs(220,262) or the WWW(252) of Internet(254).
