Abstract

A method for offering an incoming call switching service automatically in an automatic telephone answering system by remotely registering a telephone number of a desired destination using a remote telephone system. Therefore, the telephone number of the desired destination need not be registered directly. Moreover, since the incoming call is switched only during a predetermined time period, the telephone system can be used outside of the incoming call switching service conveniently even when the user forgets to set the incoming call switching function.

Claims

1. A method for offering an incoming call switching service in a telephone system subscribed to an incoming call switching system provided by an exchange system, comprising the steps of:

forming an electro-optical speech path upon detection of an incoming call from a caller via a telephone line;

automatically sending an answering message to the caller to inform the caller available modes of operation including to record a voice message in said telephone system, and to remotely control registration of a telephone number of a desired destination for an incoming call in a remote control mode;

when the caller selects the remote control mode to remotely control registration of the telephone number of said desired destination, sending a mode selection guide message to the caller to inform the caller selection of an incoming call switching mode;

when the caller selects the incoming call switching mode, sending a registration guide message to the caller to request input of the telephone number of said desired destination;

when the caller inputs the telephone number of said desired destination, storing the input telephone number of said desired destination in said telephone system; and

automatically dialing a service code corresponding to an incoming call switching service to register a stored telephone number of said desired destination at said exchange system for enabling said exchange system to automatically switch all future incoming calls received by said telephone system to a registered telephone number of said desired destination.

2. The method of claim 1, further recording the voice message from the caller, when the caller does not select the remote control mode.

3. The method of claim 1, further performing a corresponding remote control function, when the caller does not select the incoming call switching mode.

4. The method of claim 1, further comprised of said service code corresponding to *+88+the input telephone number of said desired destination+*.

5. The method of claim 1, further comprised of said caller representing a user who desires to remotely set said telephone system to perform the incoming call switching service.

6. A method for registering a telephone number of a desired destination and an incoming call switching cancellation time through a telephone system subscribed to an incoming call switching service provided by an exchange system, said method comprising the steps of:

forming an electro-optical speech path upon detection of an incoming call from a caller via a telephone line;

automatically sending an answering message to the caller to inform the caller available modes of operation including to record a voice message in said telephone system, and to remotely control registration of a telephone number of a desired destination for an incoming call in a remote control mode;

when the caller selects the remote control mode to remotely control registration of the telephone number of said desired destination, sending a mode selection guide message to the caller to inform the caller selection of an incoming call switching mode;

when the caller selects the incoming call switching mode, sending a registration guide message to the caller to request registration of the telephone number of said desired destination;

when the caller inputs the telephone number of said desired destination, storing an input telephone number of said desired destination in said telephone system;

sending a call switching time guide message to the caller to request input of the incoming call switching cancellation time;

when the caller inputs the incoming call switching cancellation time of a predetermined period, storing an input set time in said telephone system;

automatically dialing a service code corresponding to an incoming call switching service to register the input telephone number of said desired destination at said exchange system for enabling said exchange system to automatically switch all future incoming calls received by said telephone system to the registered telephone number of said desired destination; and

automatically dialing a service cancellation code requesting cancellation of said incoming call switching service to register the input set time at said exchange system for enabling said exchange system to automatically switch all future incoming calls received by said telephone system to the registered telephone number of said desired destination only during a predetermined period.

7. The method of claim 6, further recording the voice message from the caller, when the caller does not select the remote control mode.

8. The method of claim 6, further performing a corresponding remote control function, when the caller does not select the incoming call switching mode.

9. The method of claim 6, further comprised of said service code corresponding to *+88+input telephone number of said desired destination +*.

10. The method of claim 6, further comprised of said service cancellation code for canceling said incoming call switching service corresponding to #+88+#.

11. The method of claim 6, further comprising the steps of:

driving a timer for said predetermined period after the set time is input by the caller; and

automatically dialing said service cancellation code for canceling said incoming call switching service when said predetermined time has elapsed.

12. The method of claim 11, further comprised of said service cancellation code for canceling said incoming call switching service corresponding to #+88+#.

13. A telephone system subscribed to an incoming call switching service provided by an exchange system, comprising:

a memory for storing therein an answering message to respond to an incoming call from a caller via a telephone line, and a plurality of guide messages to guide the caller to control registration of a telephone number of a desired destination for offering an incoming call switching service;

means for detecting the incoming call from the caller via said telephone line; and

a controller for controlling a remote registration of the telephone number of said desired destination by;

forming an electro-optical speech path upon detection of an incoming call from the caller;

automatically sending an answering message to the caller to inform the caller available modes of operation including to record a voice message in said telephone system, and to remotely control registration of a telephone number of a desired destination for an incoming call in a remote control mode;

when the caller selects the remote control mode to remotely control registration of the telephone number of said desired destination, sending a mode selection guide message to the caller to inform the caller selection of an incoming call switching mode;

when the caller selects the incoming call switching mode, sending a registration guide message to the caller to request input of the telephone number of said desired destination;

when the caller inputs the telephone number of said desired destination, storing the input telephone number of said desired destination in said memory; and

automatically dialing a service code corresponding to an incoming call switching service to register a stored telephone number of said desired destination at said exchange system for enabling said exchange system to automatically switch all future incoming calls to be received by said telephone system to a registered telephone number of said desired destination.

14. The telephone system of claim 13, further comprised of said controller recording the voice message from the caller in said memory, when the caller does not select the remote control mode.

15. The telephone system of claim 13, further comprised of said controller performing a corresponding remote control function, when the caller does not select the incoming call switching mode.

16. The telephone system of claim 13, further comprised of said service code corresponding to *+88+input telephone number of said desired destination +*.
