Abstract

[Summary] [PROBLEMS] When an extension number is given by a dial-in service and a number display service is subscribed, a call is received only from a specific person, and a call from any specific person is received before starting a call. If a specific person uses a public telephone or the like in response to a request to distinguish whether there is, the request cannot be fulfilled. SOLUTION: When an outgoing telephone number processing unit 14 detects outgoing call from a public telephone, a main control unit 12 is provided.
Outputs the dial-in extension number information from the exchange 2 to the extension number collating unit 16. The extension number matching unit 16 detects an extension number from the dial-in extension number information, and compares the detected extension number with the extension number stored in the extension number storage unit 15. When the extension number matching unit 16 detects a match, the main control unit 12 outputs the content stored in the display content storage unit 18 to the display unit 19.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone capable of receiving caller telephone number information from a public telephone network.

[0002]

2. Description of the Related Art Public telephone line providers provide a dial-in service as an additional service. If the subscriber has also subscribed to the dial-in service, one or more dial-in numbers (extensions) can be used in addition to the subscriber telephone number. A subscriber terminal (telephone) that has subscribed to the dial-in service can also receive an incoming call by extension. Therefore, if only the specific person is informed of the extension number, calls to the telephone can be limited to the specific person. That is, when the call is received by the extension number, it is understood that the call is from a specific person.

However, when a plurality of extension numbers are assigned and each extension number is disclosed to a different person, when a call is received by extension number, it is immediately determined from whom the call is received. I can't.

[0004] Public telephone line providers provide a caller telephone number notification service (so-called number display service) as an additional service. When the subscriber subscribes to the number display service, the telephone can display the telephone number of the caller. Therefore, the user can recognize from whom the call was received by looking at the displayed caller telephone number before starting the call. Therefore, even when a call is received with an extension number that is open to a limited specific person, it is possible to immediately recognize from which specific person the call is received by looking at the displayed caller telephone number.

[0005]

However, even if an attempt is made to specify the caller by the number display, if the caller uses a public telephone or the like, the telephone is called from a "public telephone". Can only be displayed. Then, it is not possible to recognize from whom the call is received before the call starts. In other words, when an extension number is given by the dial-in service and the number display service is subscribed, only a specific person receives a call,
In addition, there is a problem in that, when a specific person uses a public telephone or the like, the request cannot be fulfilled in response to a request to distinguish from which specific person the call is received before the call starts.

Accordingly, an object of the present invention is to provide a telephone capable of easily specifying a caller even when a call is made to an extension number using a public telephone while utilizing a number display. And

[0007]

The telephone according to the present invention comprises:
A telephone with a number display and a dial-in compatible telephone (a telephone compatible with a modem dial-in), a telephone number receiving unit for detecting caller telephone number information and dial-in extension telephone number information from an exchange, and storing a specific extension number. Extension number storing unit, a calling telephone number processing unit for detecting whether the caller is a public telephone, and an extension number and an extension number storing unit based on dial-in extension telephone number information when the caller is a public telephone. And an extension number collating unit that outputs information indicating the comparison with the extension number stored in the extension number.

[0008] The telephone further includes a display unit and a display content storage unit for storing specific display content, and when the extension number collating unit detects a match, the content stored in the display content storage unit is displayed on the display unit. It may be configured to do so. Further, when the extension number collating unit detects a mismatch, it may be configured to display on the display unit that the call is from a public telephone. Then, when the caller is not a pay phone, the caller telephone number based on the caller telephone number information may be displayed on the display unit.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a telephone according to the present invention. A telephone 1 that supports modem dial-in is connected to an exchange 2 via a public line 3. In the telephone 1, the line control unit 11 controls connection with the public line 3. The main control unit 12 includes the line control unit 1
When 1 detects an incoming call, it causes the telephone number receiving unit 13 to detect the extension number of the dial-in from the exchange 2 and the caller telephone number. The calling telephone number processing unit 14 detects whether the caller is a public telephone.

One of the extension numbers is stored in the extension number storage section 15 in advance. The extension number matching unit 16
It is detected whether or not the extension number at the time of the incoming call matches the extension number stored in the extension number storage unit 15. Information indicating a specific person who has published the extension number is stored in the display content storage unit 18 in advance. When the extension number matching unit 16 detects a match, the information stored in the display content storage unit 18 is displayed on the display unit 19.

A voice signal from the public line 3 is given to a handset 21 via a line control unit 11 and a speech circuit 20, and a speech signal from the handset 21 is transmitted to the speech circuit 2.
0 to the public line 3 via the line control unit 11. The main control unit 12, the telephone number receiving unit 13, the outgoing telephone number processing unit 14, and the extension number checking unit 16 are realized by, for example, a microcomputer.

Next, the operation will be described with reference to the flowchart of FIG. When the line control unit 11 detects an incoming call, the telephone number receiving unit 13 detects dial-in extension number information and caller telephone number information transmitted from the exchange 2 in accordance with an instruction from the main control unit 12. (Step S
1). The detected caller telephone number information and dial-in extension number information are input to the main control unit 12.

The main control unit 12 outputs caller telephone number information to a caller telephone number processing unit 14. The calling telephone number processing unit 14 determines whether or not the caller is a public telephone based on the caller telephone number information (step S2). In addition,
The exchange 2 sets information indicating that a call is made from a public telephone in the caller telephone number information.

When the outgoing telephone number processing unit 14 detects that the call is not from a public telephone, the main control unit 12 outputs the received caller telephone number to the display unit 19. Therefore, the caller telephone number is displayed on the display unit 19 (step S).
3). When the outgoing telephone number processing unit 14 detects that the call is from a public telephone, the main control unit 12 outputs the dial-in extension number information to the extension number matching unit 16.
The extension number collating unit 16 detects an extension number from the dial-in extension number information (step S4), and compares the detected extension number with the extension number stored in the extension number storage unit 15 (step S5).

When the extension number collating unit 16 detects a match,
The main control unit 12 outputs the content stored in the display content storage unit 18 to the display unit 19. Therefore, the content stored in the display content storage unit 18 is displayed on the display unit 19 (step S6). When the extension number matching unit 16 detects a mismatch, the main control unit 12 outputs information indicating “public telephone” to the display unit 19. Therefore, information indicating that the telephone is a "public telephone" (for example, a mark indicating "a public telephone" or a character "KOUDENWA") is displayed on the display unit 19 (step S7).

As described above, when an incoming call is received from a public telephone at the extension number registered in the extension number storage unit 15, the content stored in the display content storage unit 18 is displayed on the display unit 19. Is done. Therefore, when the extension number is known only to a specific person and the specific person makes a call from a public telephone, information indicating the specific person is displayed on the display unit 19. For example, the specific person is a customer A
If you are a person named "xxx", you can read "Tri-Hikisaki A x
The information “xx” is stored in the display content storage unit 18. Then, “Thirikisaki A × XXX” is displayed on the display unit 9.

Consider a case where an extension number is disclosed to a plurality of specific persons. For example, if the number is disclosed to five friends, the information "YUJIN" is stored in the display content storage unit, and when the friend makes a call from home, each caller's telephone number is displayed on the display unit 9. When a call is made from a public telephone, "YUJIN" is displayed. In other words, in the case of an incoming call to this extension, instead of displaying everything as “Ujin”, the calling phone number is displayed by determining whether it is a public phone or not, and the only person that is a feature of the number display service is It is also possible to specify.

Therefore, according to this embodiment, when a specific person who knows the extension number registered in extension number storage section 15 makes a call from a public telephone, it is immediately notified that there is an incoming call from the specific person. Can be recognized. In addition, when a call is made to this extension number from home, the caller's telephone number can be displayed to identify the only person.

[0019]

As described above, according to the present invention, a telephone is detected as to whether or not the caller is a public telephone, and if the caller is a public telephone, the extension based on the dial-in extension telephone number information is provided. The number is compared with the extension number stored in the extension number storage unit, and when the numbers match, the information to that effect is output, so that the extension number is called using a public telephone. However, there is an effect that the caller can be easily specified.
