JPH05160904A - Transmitting system due to automatic storage of caller number - Google Patents

Abstract

PURPOSE:To enable transmission without confirming a caller number and operating dials in the case of executing the transmission to a caller after speaking is finished when a call is incoming from the caller housed in an ISDN network. CONSTITUTION:When an extension subscriber 1 responds to the call incoming from a subscriber 2 housed in an ISDN network 9 and finishes speaking, a central control unit 7 registers a call originating number and a call originating sub address in a message received from the ISDN network 9 through a D channel controller 5 on a caller number registration memory 9 and afterwards, when the extension subscriber 1 dials any special number, based on the registered information, transmission is executed to the subscriber 2 housed in the ISDN network 9.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic automatic private branch exchange, and more particularly to receiving an incoming call from a caller accommodated in an ISDN network.
The present invention relates to a redialing method to a calling party.

[0002]

2. Description of the Related Art Conventionally, it has been possible for an electronic automatic private branch exchange to store the calling party number of an incoming call and make a call after the end of the call. Therefore, when the called party makes a call to the calling party after disconnecting the incoming call, the called party hears the caller's number orally when disconnecting the incoming call and dials the calling party number. Was.

[0003]

In the case of the above-mentioned conventional restarting method after an incoming call, it is impossible to automatically register the calling party number at the time of an incoming call. When the caller's number is verbally confirmed and the call is returned after the end of the call, there is the trouble of dialing the caller's number.

An object of the present invention is to automatically register a calling party number when an incoming call is received, and to automatically send the calling party number automatically by the registered calling party number when the called party makes a call to the calling party. It is to provide a calling method by memory.

[0005]

According to the call originator number automatic storage method of the present invention, an electronic automatic private branch exchange having a function of being accommodated in an ISDN network receives a calling number and a calling subaddress from the network. Means and means for registering the caller number information in the caller number registration memory are provided, and when making a call, the caller number information of the caller number information registering means is used for automatic transmission.

[0006]

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. Extension subscriber 1, subscriber 2 accommodated in an ISDN network, extension subscriber line circuit 3, ISDN trunk 4, D channel control. It comprises a device 5, a switch 6, a central control device 7, a calling party number registration memory 8 and an ISDN network 9.

Next, the operation will be described. ISDN network 9
The subscriber 2 accommodated in (1) sends a call setup message to the ISDN network 9 and makes the ISDN trunk 4 receive the call. When the extension subscriber 1 responds to the incoming call and performs a recovery operation at the end of the call, the central controller 7 sends the calling number and the calling subaddress in the message received from the ISDN network 9 through the D channel controller 5 to the calling party. The number is registered in the area of the number registration memory 8 assigned to the extension subscriber 1. After that, when the extension subscriber 1 makes a call to the subscriber 2 accommodated in the ISDN network, when the extension subscriber 1 dials a special number for this calling method, the central control unit 7 recognizes this. The call setting message is edited using the information registered in the dial information registration memory 8 as the called number and the called sub address, and sent to the ISDN network 9.

[0009]

As described above, according to the present invention, the calling number and the calling subaddress are received from the ISDN network, and the calling number information is registered in the calling number registration memory.
When the called party makes a call to the calling party after the termination of the incoming call from the calling party accommodated in the ISDN network, the calling party simply calls a special number and the calling party is stored in the calling party number registration memory. Since information is automatically transmitted, there is an effect that the troublesomeness of checking the calling number and dialing the number of the calling party can be eliminated.
