An IP telephone system includes a source IP telephone apparatus, a Web server and an ENUM server. The source IP telephone apparatus is connected to an IP network. The Web server stores predetermined information regarding a user of the source IP telephone apparatus and transmits, to a destination IP telephone apparatus, the predetermined information in response to a request from the destination IP telephone apparatus. The ENUM server stores a NAPTR resource record which includes a URI utilized for obtaining the predetermined information stored in the Web server. In the IP telephone system, the destination IP telephone apparatus transmits, to the ENUM server, a request for a NAPTR resource record of the source IP telephone apparatus and transmits, to the Web server, a request for the predetermined information regarding the source IP telephone apparatus according to the obtained NAPTR resource record.
