Abstract
An IP telephone system includes a source IP telephone apparatus, a destination telephone apparatus, a Web server and an ENUM server. The IP telephone apparatuses are connected to an IP network. The Web server stores call reception screen information corresponding to a telephone number assigned to the source or destination IP telephone apparatus. The ENUM server stores a NAPTR resource record in which a URI specifies link information related to the call reception screen information stored on the Web server. In the IP telephone system, the IP telephone apparatus that has received a call transmits, to the ENUM server, a query for a NAPTR record corresponding to an intended recipient'"'"'s telephone number. The IP telephone apparatus then transmits, to the Web server, a request for the call reception screen information corresponding to the intended recipient'"'"'s telephone number according to the obtained NAPTR resource record, and displays a call reception screen according to the obtained call reception screen information.
