An ENUM system includes a Web server and an ENUM server. The Web server stores first NAPTR records corresponding to an ENUM client and another ENUM client on an IP network. The ENUM server stores second NAPTR records in which first URIs are associated with predetermined information for being linked to the Web server. In the ENUM system, the ENUM client transmits, to the ENUM server, a query for the second NAPTR record of the another ENUM client. The ENUM client then transmits, to the Web server, a request for access to the first URI included in the received second NAPTR record, and obtains the first NAPTR record corresponding to the another ENUM client.

A CPU in an IP telephone apparatus automatically controls to transmit, from a network I / F to an ENUM server, a request for deleting a NAPTR record when an absent key is pressed. The CPU regularly transmits, from the network I / F to the ENUM server, an inquiry for a NAPTR record of another IP telephone apparatus. When the CPU receives, from the ENUM server via the network I / F, a response indicating that the NAPTR record of another IP telephone apparatus has been deleted, in response to the inquiry, the CPU turns OFF a lamp indicating that the user is available.

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 ring tone 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 data related to the ring tone information stored in 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 ring tone information corresponding to the intended recipient's telephone number according to the obtained NAPTR resource record, and sounds a ring tone according to the obtained ring tone information

When a call recipient name is clicked on a search result screen of a phonebook search system, an ENUM server is notified of an html file name which displays the call recipient profile, which is personal data. The ENUM server extracts a URI corresponding to an IP telephone service for the call recipient from a NAPTR record based on the html file name, and transmits the URI to a source IP telephone apparatus. The source IP telephone apparatus then becomes able to place a call to a destination IP telephone apparatus, using the URI corresponding to the IP telephone service for the call recipient.
