Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a private branch exchange which accommodates an ISDN line and can notify caller ID notification data or connection destination number notification data to an ISDN public network.

[0002]

2. Description of the Related Art In recent years, with the rapid spread of the Internet and information communication equipment, the development of information communication infrastructure has been promoted in various countries around the world. The functions required of the private branch exchanges accommodating the lines have also become more diverse.

[0003] Various additional services are provided from stations using ISDN lines. For example, a caller ID notification (CLI) for notifying a called party of a caller's number through a line is provided.
P) service and connection destination number notification (COLP) service that notifies the caller of the called party's number through the line. By using these services, it is possible to know the other party's number before calling and use a personal computer etc. Customer management service (associating the caller ID received with the address like a delivery service at a pizzeria, so there is no need to query the address when ordering for the second time)
Becomes possible.

[0004] A method of generating and notifying a caller ID notification (CLIP) and a connection destination number notification (COLP) in a conventional private branch exchange accommodating an ISDN line will be described below.

FIG. 14 is an explanatory diagram showing a system using a conventional private branch exchange. In FIG. 14, reference numeral 500 denotes a private branch exchange. 501 is an ISDN line. Reference numeral 502 denotes an extension terminal connected to the extension of the private branch exchange 500. Five
03 is an external subscriber terminal.

FIG. 2 shows that the private branch exchange 500 has an incoming call analysis data table that stores a link between a line number and an extension number, and associates an incoming extension terminal with a line number. For example, the line number "092-111-1000
If an incoming call arrives at the "100" extension terminal (1)
Incoming call.

First, a conventional caller ID notification (CLIP) will be described. An extension terminal, for example, extension terminal (1) 502
Sends a number "03-411-1111" of the subscriber terminal 503 to the ISDN line,
Number “092-111-100” associated with extension terminal (1)
"0" as the caller number to the ISDN line (CL
IP). The transmitted number is notified to the subscriber terminal 503 through the ISDN line.

Dialing "092-111-1000" from the ISDN line to the private branch exchange 500 together with a signal indicating an incoming call and a number indicating the connected party, that is, "092-111-1000", and a calling number of "03-411-1111" Is notified. The private branch exchange 500 refers to the incoming call analysis data table and searches for an extension number corresponding to the connection partner number "092-111-1000". From the search result, the extension associated with the number “092-111-1000” is found to be the extension number “100”,
The call arrives at the extension terminal (1). In this case, "092-111-1000" is sent to the ISDN line as the connection destination number (COL
P), the transmitted number is notified to the subscriber terminal 503 through the ISDN line.

[0009] By the way, the connection partner number "092-111-1"
If the extension corresponding to "000" is busy, the call is transferred to the extension set as the transfer destination. That is, if the extension number "101" is set as the transfer destination, the extension terminal ( The call arrives at 2) In this case, the number "092-111-1001" set in association with the extension terminal (2)
To the ISDN line, and the transmitted caller ID is IS
The subscriber terminal 503 is notified via the DN line.

[0010]

However, conventionally, since only one line number is associated with the extension number of each extension terminal, the number notified to the external destination when each extension terminal 200 originates and receives a call is received. Was only this one number and could not give another notice. Also, since specialized knowledge is required for maintenance of the private branch exchange,
In order to change the notification of the caller ID and the notification of the connection destination number, it is necessary to request the administrator who performs the maintenance, and the change cannot be easily made according to the situation.

When a caller is connected to an extension different from the extension desired by the caller due to call forwarding or the like, the number associated with the connected extension is sent to an external party as a connection destination number notification (COLP). Will be. If the other party's terminal is configured to be able to capture the destination number information, the destination number corresponding to an extension different from the desired extension will be captured, and if you try to make a call again later, the original The extension may be connected to a different extension from the extension to be connected.

When the private branch exchange is connected to a plurality of ISDN lines as external lines, the caller ID displayed on the connection destination terminal in relation to the extension to be transmitted differs, which is inconvenient. Met.

In view of the above-mentioned conventional problems, the present invention makes it possible to easily change the caller ID notification number and the connection destination notification number from each extension terminal. It is intended to provide a private branch exchange which can notify a caller number notification number and a connection destination number notification number, thereby facilitating charge metering, telemarketing (secretary agency), and the like.
