ABSTRACT:
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.
