Abstract

The present invention is intended to provide a call system which can authenticate a call initiation request from a proxy dial server apparatus with a caller number specified by the proxy dial server apparatus without adding special processing. In the configuration according to the present invention, proxy dial server apparatus first requests telephone server apparatus to call a telephone number of a user. In this event, proxy dial server apparatus uses the telephone number of the user as a caller ID. Upon receipt of a call request, telephone server apparatus transmits an authentication challenge to proxy dial server apparatus for authenticating the caller ID. Upon receipt of the authentication challenge, proxy dial server apparatus generates a response using a user ID and a password previously registered in association with the user'"'"'s telephone. This results in successful authentication by telephone server apparatus, allowing a call to terminate at the user'"'"'s telephone number.

Claims

1. A call system having a proxy dial server apparatus which acts as a substitute to perform a call initiation operation involved in making a point-to-point call between a calling terminal and a called terminal based on control of a telephone server apparatus, wherein:

said proxy dial server apparatus comprises;

means for transmitting to said telephone server apparatus a request for calling said calling terminal and a request for calling said called terminal based on information on a calling party; and

means for creating authentication data for an authentication request from said telephone server apparatus in response to the call request based on the information about the calling party, and transmitting the information to said telephone server apparatus.

2. The call system according to claim 1, wherein said information about the calling party includes at least user identification information and a password of the calling party which are utilized in authentication processing of a network device.

3. The call system according to claim 1, wherein said telephone server apparatus handles a call initiated from said proxy dial server apparatus in a manner similar to a call from an ordinary terminal.

4. The call system according to claim 1, wherein said proxy dial server apparatus transmits the call request and the authentication data to said telephone server apparatus when a request for a connection to said called terminal is entered by means other than said calling terminal.

5. The call system according to claim 4, wherein said means other than said calling terminal includes at least means for instructing call initiation from browser software and means for executing a time-triggered call initiation program which is includes a call initiation time.

6. A proxy dial server apparatus for acting as a substitute to perform a call initiation operation involved in making a point-to-point call between a calling terminal and a called terminal based on control of a telephone server apparatus, said proxy dial server apparatus comprising:

means for transmitting to said telephone server apparatus a request for calling said calling terminal and a request for calling said called terminal based on information on a calling party; and

means for creating authentication data for an authentication request from said telephone server apparatus in response to the call request based on the information on the calling party, and transmitting the information to said telephone server apparatus.

7. The proxy dial server apparatus to claim 6, wherein said information on the calling party includes at least user identification information and a password of the calling party which are utilized in authentication processing of a network device.

8. The proxy dial server apparatus according to claim 6, wherein said telephone server apparatus handles a call initiated from said proxy dial server apparatus in a manner similar to a call from an ordinary terminal.

9. The proxy dial server apparatus according to claim 6, wherein said proxy dial server apparatus transmits the call request and the authentication data to said telephone server apparatus when a request for a connection to said called terminal is entered by means other than said calling terminal.

10. The proxy dial server apparatus according to claim 9, wherein said means other than said calling terminal includes at least means for instructing call initiation from browser software and means for executing a time-triggered call initiation program which is includes a call initiation time.

11. A proxy dial method for use by a call system which has a proxy dial server apparatus for acting as a substitute to perform a call initiation operation involved in making a point-to-point call between a calling terminal and a called terminal based on control of a telephone server apparatus, wherein:

said proxy dial server apparatus executes;

processing for transmitting to said telephone server apparatus a request for calling said calling terminal and a request for calling said called terminal based on information on a calling party; and

processing for creating authentication data for an authentication request from said telephone server apparatus in response to the call request based on the information on the calling party, and transmitting the information to said telephone server apparatus.

12. The proxy dial method according to claim 11, wherein said information on the calling party includes at least user identification information and a password of the calling party which are utilized in authentication processing of a network device.

13. The proxy dial method according to claim 11, wherein said telephone server apparatus handles a call initiated from said proxy dial server apparatus in a manner similar to a call from an ordinary terminal.

14. The proxy dial method according to claim 11, wherein said proxy dial server apparatus transmits the call request and the authentication data to said telephone server apparatus when a request for a connection to said called terminal is entered by means other than said calling terminal.

15. The proxy dial method according to claim 14, wherein said means other than said calling terminal includes at least means for instructing call initiation from browser software and means for executing a time-triggered call initiation program which is registered with a call initiation time.

16. A program for implementing a proxy dial method for use by a call system which has a proxy dial server apparatus for acting as a substitute to perform a call initiation operation involved in making a point-to-point call between a calling terminal and a called terminal based on control of a telephone server apparatus, wherein:

said program causes a computer of said proxy dial server apparatus to execute;

processing for transmitting to said telephone server apparatus a request for calling said calling terminal and a request for calling said called terminal based on information on a calling party; and

processing for creating authentication data for an authentication request from said telephone server apparatus in response to the call request based on the information on the calling party, and transmitting the information to said telephone server apparatus.
