Abstract

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.

Claims

1. An IP telephone system comprising:

a Web server configured to store predetermined information regarding a user of a calling IP telephone apparatus corresponding to a predetermined URI;

an ENUM server configured to store a NAPTR (Naming Authority Pointer) resource record, the NAPTR resource record including an ENUM domain name corresponding to the predetermined URI stored in the Web server; and

an IP telephone apparatus, comprising;

a display configured to display data; and

a controller configured to;

receive, from the calling IP telephone apparatus, a predetermined message command for a connection with the IP telephone apparatus, the predetermined message command including a telephone number of the calling IP telephone apparatus;

generate an ENUM domain name based on the telephone number of the calling IP telephone apparatus;

transmit, to the ENUM server, a request for transmitting, to the IP telephone apparatus, the NAPTR resource record corresponding to the generated ENUM domain name;

receive, from the ENUM server, the corresponding NAPTR resource record;

access the Web server, based on the predetermined URI included in the received NAPTR resource record;

receive, from the Web server, the predetermined information regarding the user of the calling IP telephone apparatus corresponding to the predetermined URI; and

control the display to display the received predetermined information regarding the user of the calling IP telephone apparatus.

2. The IP telephone system according to claim 1, wherein the predetermined information regarding the user of the calling IP telephone apparatus comprises one of a telephone number of the calling IP telephone apparatus, a name of the user, an address of the user, an e-mail address of the user, and photo data representing a face of the user.

3. The IP telephone system according to claim 1, wherein the predetermined message command comprises an INVITE message specified in a SIP protocol.

4. The IP telephone system according to claim 1, wherein the predetermined message command comprises a SETUP message specified in a H.323 protocol.

5. The IP telephone system according to claim 1, wherein the NAPTR resource record stored in the ENUM server indicates a predetermined protocol utilized for accessing the Web server, and the IP telephone apparatus accesses the Web server based on the predetermined protocol.

6. The IP telephone system according to claim 5, wherein, when the NAPTR resource record received by the IP telephone apparatus does not indicate the predetermined protocol, the IP telephone apparatus transmits, to the calling IP telephone apparatus, a message command indicating that the IP telephone apparatus is unavailable.

7. The IP telephone system according to claim 5, wherein the predetermined protocol comprises a HTTP protocol.

8. The IP telephone system according to claim 5, wherein the predetermined protocol comprises a LDAP protocol.

9. An IP telephone apparatus connected to a Web server and to an ENUM server, the Web server storing predetermined information regarding a user of a calling IP telephone apparatus corresponding to a predetermined URI, the ENUM server storing a NAPTR (Naming Authority Pointer) resource record, the NAPTR resource record including an ENUM domain name corresponding to the predetermined URI stored in the Web, the IP telephone apparatus comprising:

a display configured to display data; and

a controller configured to;

receive, from the calling IP telephone apparatus, a predetermined message command for a connection with the IP telephone apparatus, the predetermined message command including a telephone number of the calling IP telephone apparatus;

generate an ENUM domain name based on the telephone number of the calling IP telephone apparatus;

transmit, to the ENUM server, a request for transmitting, to the IP telephone apparatus, the NAPTR resource record corresponding to the generated ENUM domain name;

receive, from the ENUM server, the corresponding NAPTR resource record;

access the Web server, based on the predetermined URI included in the received NAPTR resource record;

receive, from the Web server, the predetermined information regarding the user of the calling IP telephone apparatus corresponding to the predetermined URI; and

control the display to display the received predetermined information regarding the user of the calling IP telephone apparatus.
