Abstract

(57) [Summary] (Corrected) [Purpose] Nippon Telegraph and Telephone Co., Ltd. Telephone call number notification application by dial-in service etc. can be taken out in a state that can be processed by a computer, and the telephone call number identification application system can be easily and inexpensively. It is possible to build. [Structure] A primary response signal is returned as a calling signal, a called number is received as a DTMF signal from an outside line, and a reception completion signal is returned (1). In the meantime, the incoming call number is sent to the computer G, and the incoming call number receiving and saving program receives and saves the incoming call number (2). The service determination program determines which service is to be executed based on the stored called number (3). Then, the secondary response signal is returned, and the polarity of the two lines is restored, and the normal call is established (4), and the service process is executed (5).

Description

[Detailed description of the device]

[Industrial applications]

 The present invention is to take out the notified incoming call number in a computer processable state in order to switch the service and change the conversation contents by telephone with the incoming call number by Nippon Telegraph and Telephone Corporation dial-in service etc. It is a device.

Correspondence differs depending on which department is calling. If the receiving department is unattended, other departments may be unfamiliar. In order to respond quickly at this time, it is possible to respond smoothly if the guidance information of the receiving department is automatically displayed on the computer.

In addition to conversation, fax transmission / reception, conversation content recording, recording / playback, answering machine, automatic answering from an answering machine, pager, mobile phone call, communication between computers, or a combination thereof In order to enable various types of services by telephone, it is necessary to link the telephone with the computer.

In order to save telephone expenses and optimize the number of external lines, Nippon Telegraph and Telephone Corporation dial-in services, etc., make direct calls to a certain department or service while narrowing down the number of external lines. It makes it possible to do. However, in this dial-in service and the like, it is necessary to logically determine the physically few external lines by the notified called number.

From the above, in order to enable various types of services by telephone while suppressing telephone costs, it is necessary to have a device that easily retrieves the notified incoming number in a computer processable state. Also, if it is not cheap, there will be fewer establishments that will benefit.

2. Description of the Related Art Conventional devices that perform this function include a digital exchange and a dedicated electronic computer.

[0007]

[Problems to be solved by the device]

 The conventional technology is expensive, and because it is a dedicated product, maintenance and construction of an application system must be done by the manufacturer. With this, even if there are convenient functions, the number of establishments that can be installed will be limited.

By combining products that are sold to individuals, it is possible to provide a function that allows an application system for identifying a called number to be easily constructed at low cost.

[0009]

[Means for Solving the Problems]

 To achieve the above purpose, as shown in Fig. 1, Nippon Telegraph and Telephone Corporation dial-in service etc., fax modem with voice function (supports extended AT commands and AT commands), personal computer, incoming call number storage program. ,,. The processing procedure is described below.

FIG. 1 (1) A primary response signal is returned by a calling signal. Then, it receives the incoming call number from the outside line with a DTMF signal and returns a reception completion signal.

FIG. 1 (2) During this time, the called number is sent to the electronic computer through RS-232C. In the electronic computer, the program for receiving and storing the telephone number is received and stored.

The service determination program shown in FIG. 1 (3) determines which service is to be executed based on the stored called number.

FIG. 1 (4) Then, the secondary response signal is returned. Next, the two lines are returned to the normal polarity and the normal call is in progress. 1 (5) Executes service processing.

[0014]

[Action]

 By combining products that are sold to individuals, it is possible to build an application system for identifying the called number easily and at low cost.

[Effect of device]

 Since the telephone lines can be assigned to multiple services / one outside line, the number of outside lines can be narrowed down. As a result, telephone costs can be reduced, and it is easy to increase the number of services. In addition to conversations, various types of telephone calls, such as fax transmission / reception, conversation content recording, recording / playback, answering machine, answering machine, pager, mobile phone call, computer-to-computer communication, or a combination thereof, are used. The service of can be assigned to the incoming number. It was possible to link the telephone and the electronic computer by using a digital exchange, but they were not benefiting everywhere because they were so expensive. In the present invention, they can be realized at low cost.
