Abstract

An IP telephone system includes an IP telephone apparatus, a Web server and an ENUM server. The IP telephone apparatus is connected to an IP network. The Web server registers talk volume information corresponding to a telephone number assigned to the IP telephone apparatus. The ENUM server registers a NAPTR resource record in which a URI specifies link data related to the talk volume information registered 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 a targeted recipient phone number. The IP telephone apparatus then transmits, to the Web server, a request for the talk volume information corresponding to the targeted recipient phone number according to the returned NAPTR resource record, and adjusts the talk volume according to the returned talk volume information.

Claims

1. An IP telephone system comprising:

an IP telephone apparatus that is connected to an IP network;

a Web server that registers talk volume information corresponding to a telephone number assigned to said IP telephone apparatus, and returns the talk volume information in response to a request from said IP telephone apparatus; and

an ENUM server that registers a NAPTR resource record in which a URI specifies link data related to the talk volume information, the information being registered in said Web server, and returns the NAPTR resource record in response to a query from said IP telephone apparatus,

wherein said IP telephone apparatus that has received a call transmits, to said ENUM server, a query for a NAPTR resource record according to a targeted recipient phone number, and transmits, to said Web server, a request for the talk volume information corresponding to the targeted recipient phone number according to the returned NAPTR resource record, and adjusts talk volume according to the returned talk volume information.

2. The IP telephone system according to claim 1, wherein an http protocol is specified in the NAPTR resource record registered in said ENUM server, and said IP telephone apparatus that has received a call transmits, to said Web server, the request for the talk volume information corresponding to the targeted recipient phone number according to the http protocol.

3. The IP telephone system according to claim 1, wherein said IP telephone apparatus that has received a call obtains the targeted recipient phone number based on a description of a received INVITE message.

4. An IP telephone apparatus that is connected to a Web server and an ENUM server, the Web server registering talk volume information corresponding to a telephone number assigned to an IP telephone apparatus on an IP network, the ENUM server registering a NAPTR resource record in which a URI specifies link data related to the talk volume information, the information being registered in the Web server, the IP telephone apparatus comprising:

a query unit that transmits, to the ENUM server, a query for a NAPTR resource record according to a targeted recipient phone number, when receiving a call from another IP telephone apparatus on the IP network;

a requester that transmits, to the Web server, a request for the talk volume information corresponding to the targeted recipient phone number according to the returned NAPTR resource record; and

an adjuster that adjusts talk volume according to the returned talk volume information.

5. The IP telephone apparatus according to claim 4, wherein said requester transmits, to the Web server, a request for the talk volume information corresponding to the targeted recipient phone number according to an http protocol, the protocol being specified in the NAPTR resource record registered in the ENUM server.

6. The IP telephone apparatus according to claim 4, wherein said query unit transmits a query for the NAPTR resource record according to the targeted recipient phone number obtained based on a description of INVITE message, the message being received from another IP telephone apparatus.

7. A communications method comprising:

using an IP telephone apparatus that is connected to a Web server and an ENUM server, the Web server registering talk volume information corresponding to a telephone number assigned to an IP telephone apparatus on an IP network, the ENUM server registering a NAPTR resource record in which a URI specifies link data related to the talk volume information, the information being registered in the Web server, wherein, when a call is received from another IP telephone apparatus on the IP network, a query is transmitted to the ENUM server, the query being for a NAPTR resource record according to a targeted recipient phone number, a request is transmitted to the Web server, the request being for the talk volume information corresponding to the targeted recipient phone number according to the returned NAPTR resource record, and talk volume is adjusted according to the returned talk volume information.

8. The communications method according to claim 7, wherein a request is transmitted to the Web server, the request being for the talk volume information corresponding to the targeted recipient phone number according to an http protocol, the protocol being specified in the NAPTR resource record registered in the ENUM server.

9. The communications method according to claim 7, wherein the targeted recipient phone number is obtained based on a description of INVITE message, the message being received from another IP telephone apparatus.

10. An IP telephone system comprising:

an IP telephone apparatus that registers a URI and talk volume information corresponding to a telephone number assigned to the IP telephone apparatus; and

an ENUM server that registers a NAPTR resource record specifying a URI corresponding to a telephone number assigned to said IP telephone apparatus, and returns a NAPTR resource record in response to a query from said IP telephone apparatus, wherein a source IP telephone apparatus transmits, to said ENUM server, a query for a NAPTR resource record by specifying a telephone number, and places a call based on a URI specified in the returned NAPTR resource record, and wherein a destination IP telephone apparatus adjusts talk volume according to the talk volume information corresponding to the URI specified by the source IP telephone apparatus.

11. A communications method comprising:

using an IP telephone apparatus that is connected to an ENUM server, the ENUM server registering a NAPTR resource record that specifies a URI corresponding to a telephone number assigned to an IP telephone apparatus on an IP network, and registers a URI and talk volume information corresponding to a telephone number assigned to the IP telephone apparatus,

wherein a source IP telephone apparatus transmits, to the ENUM server, a query for a NAPTR resource record by specifying a telephone number, and places a call based on a URI specified in the returned NAPTR resource record, and wherein a destination IP telephone apparatus adjusts talk volume according to the talk volume information corresponding to the URI specified by the source IP telephone apparatus.
