2. Description of the Related Art In recent years, a number display service has been implemented by NTT, and a telephone number of a calling terminal can be displayed on a display unit when a desired subscriber receives an incoming call. By using this service, the IS
The telephone number of the calling terminal that could not be displayed unless the telephones are connected to the DN line can be displayed between the telephones connected to the analog line, and the user can confirm the calling party before answering. Also, by using this service, it is possible to store the telephone number of the incoming call and leave it as a call history.

[0003]

However, even if the subscriber subscribes to the number display service for receiving the telephone number of the caller terminal, he or she has only used it to confirm the caller before answering. . Therefore, even if the telephone has a function of storing the telephone number of the incoming call and leaving it as the incoming call history, it cannot be said that these functions are effectively used. Specifically, even when it is desired to confirm the telephone number of a caller who has called from outside, it has not been possible to confirm the incoming call history with this kind of conventional telephone.

[0004] In recent years, telephones have become more sophisticated, and most telephones have an answering machine function for recording an incoming message from the other party during an absence. The incoming message recorded by such an answering machine function can be confirmed when returning home, and can also be confirmed from outside by entering a personal identification number or the like via a telephone line.

[0005] In the prior art, however, such an answering machine function makes it possible to confirm an incoming message from an outside destination, but it has not been possible to confirm the telephone number of the person who left the incoming message. For this reason, even if it is desired to call a person who has left an incoming message immediately from whereabouts, the call cannot be made unless the telephone number of this person is known.

An object of the present invention is to solve the above-mentioned problems of the prior art and to provide a method for checking the incoming call history of a telephone capable of checking the incoming call history of a telephone number that has received an incoming call from outside. I do.

Hereinafter, an embodiment of the incoming call history checking method in the telephone according to the present invention will be described in detail with reference to FIGS. 1, 2 and 3. FIGS. 1 and 2 show a series of processing flows connected by “A” and “B” surrounded by a circle.
When the telephone 10 receives the telephone number of the calling terminal from the network side at the time of an incoming call, the telephone number is analyzed by the caller IDIC 20. The result of this analysis is stored in C via input / output port 32.
It is sent to PU34. Then, when receiving the telephone number of the calling terminal, the CPU 34 displays the telephone number on the LCD display unit 26, and displays the telephone
To be stored.

The CPU 34 is connected to the ringer detection circuit 12.
If the ringer is detected a specified number of times (n times) (S10
0, S102), the hook switch circuit 14 is controlled to capture the line, and a predetermined response message is transmitted to the calling terminal by the voice synthesis ROM 22 (S104). If a DTMF signal of "#" is not detected by the DTMF receiver 18 during the transmission of the response message (S106), the CPU 34
Starts the recording / reproducing device and shifts to a process of recording an incoming message from the calling terminal (S108). When the recording process of the incoming message is completed, the CPU 34 performs a line disconnection process (S126).

On the other hand, during transmission of the response message, "#"
When the DTMF signal is detected by the DTMF receiver 18 (S106), the CPU 34 stops transmitting the response message and sends an announcement of "Please input a password" from the voice synthesis ROM 22 (S110). After transmitting the announcement, when the DTMF signal of the personal identification number is received from the calling terminal, the content is transmitted to the CPU 34 by the DTMF receiver 18.

The CPU 34 compares the personal identification number received from the DTMF receiver 18 with the personal identification number stored in the RAM 36 in advance, and confirms whether the received personal identification numbers match or not (S112). As a result, if the passwords do not match, a line disconnection process is performed (S126). If the passwords match, it is determined whether there is an incoming call history (S11).
4). If there is no incoming call history, the CPU 34
The M22 sends a message "No incoming call history" to the calling terminal (S116), and performs line disconnection processing (S126).

On the other hand, if there is an incoming call history,
By transmitting the incoming call history stored in the AM 36 to the caller terminal, the incoming call history is reproduced (S118). Specifically, the CPU 34 reads the telephone number stored in the RAM 36 and the date and time when the call was received, reads the corresponding phrase from the voice synthesis ROM 22, and transmits the phrase to the telephone line. When the announcement of the incoming call history is completed (S120) and a BT (Busy Tone) indicating that the caller terminal has performed the disconnection processing while waiting for a new command is detected (S122), the CPU 34 disconnects the line. Is performed (S126). After the reproduction, if a reproduction command is received, the process returns to step S118, and if a DTMF signal of the reproduction command is not received after a predetermined time has elapsed (S12).
4), the CPU 34 performs a line disconnection process (S12).
6).

The embodiment of the present invention has been described above.
In particular, the present invention is not limited to this. That is, in the present embodiment, it is described that the history information of the telephone number of the incoming call can be confirmed from the outside via the telephone line, but for example, it is also possible to provide a telephone number corresponding to the incoming message recorded by the answering machine function. Of course it is possible. In this case, for example, the incoming message and the corresponding telephone number may be stored in association with each other, and the corresponding telephone number may be announced by voice synthesis at the end of the incoming message. By doing so, the telephone number of the partner who left the incoming message can be checked at the same time after the incoming message ends.

It is to be noted that the telephone number of the other party who has left the incoming message is not transmitted continuously after the end of the message as described above, but is transmitted as required by key input of a predetermined DTMF signal. Is also good.
