JPH04334250A - Caller identification incoming call transfer system - Google Patents

Abstract

PURPOSE:To directly call the extension of a person in charge of a customer without through the aid of a receptionist at the time of an incoming call from the customer stored in an ISDN network so as to cancel a trouble by means of transmission. CONSTITUTION:When there is the incoming call from a subscriber 2 stored in the ISDN network, a central control unit 7 identifies a caller number in a message received from the ISDN network 12 via the D channel controller 5, retrieves the extension number of the person in charge of the customer, who is applicable, from a customer information registration memory 8 based on the caller number and transfers the incoming call to the extension concerned.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a call transfer system in an electronic automatic private branch exchange, and more particularly to a call transfer system for incoming calls from callers accommodated in an ISDN network.

0002

[Prior Art] Conventionally, in an electronic automatic private branch exchange,
When forwarding an incoming call, it has not been possible to change the forwarding destination of the incoming call depending on the calling party number.

0003

[Problems to be Solved by the Invention] In the case of the above-mentioned conventional call transfer system, it was not possible to transfer incoming calls in response to the customer, so the transfer destinations were limited. In many cases, a person other than the person in charge responds, and in some cases, it is troublesome to have to act as an intermediary.

SUMMARY OF THE INVENTION An object of the present invention is to provide a caller identification call transfer system that automatically transfers an incoming call from a customer to the extension of a customer representative.

[0005]

[Means for Solving the Problems] The caller identification call transfer system of the present invention stores in advance the extension number of the person in charge for each customer in an electronic automatic private branch exchange that is accommodated in an ISDN network and has a transfer function. Customer information registration memory and the ISD
means for receiving a calling number from the ISDN network; and means for searching the extension number of a customer-specific contact person corresponding to the received calling number from the customer information memory; is transferred to the extension of the customer in charge.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a connection state diagram of a calling party identification transfer system showing one embodiment of the present invention, in which extension subscriber 1, ISDN
Subscribers accommodated in the network 2, extension subscriber line circuit 3, ISDN trunk 4, D channel control device 5, switch 6, central control device 7, customer information registration memory 8, ringing tone generation circuit 9, ringing signal It consists of a generation circuit 10, a customer information search function 11, and an ISDN network 12.

[0008] The subscriber 2 accommodated in the ISDN network is
Sends a call setup message to the ISDN network 12, and
Incoming call to trunk 4. The central control device 7 sends a customer information recommendation function 11 based on the calling number in the message received from the ISDN network 12 through the D channel control device 5.
The extension number of the person in charge for each customer corresponding to the calling party number is retrieved from the customer information registration memory 8. Central control device 7
Then, the incoming call is transferred to the extension subscriber 1 corresponding to the searched extension number, and a paging message is sent to the ISDN network 12 via the D channel control device 5.

[0009]

[Effects of the Invention] As explained above, the present invention provides an ISDN
When receiving a call at an electronic automatic private branch exchange housed in the network, means for receiving the calling party's number from the network and searching the extension number of the person in charge for each customer for the calling party's number from a pre-recorded customer information registration memory. By providing the means,
For incoming calls from customers accommodated in the ISDN network, the extension number of the person in charge can be searched and the incoming call can be transferred to the person in charge's extension, which has the effect of eliminating the trouble caused by intermediaries.
