JPH0470089A - Forced transferring system for incoming call - Google Patents

Abstract

PURPOSE:To transfer an incoming call to either an extension or a line wire provided preliminarily without responding by operating an easy forced transfer requesting operation from a subscriber terminal at the time of the incoming call. CONSTITUTION:The incoming call from a station line 8 is connected through a station trunk 5 and switch 6 with an extension subscriber terminal 2, and a calling bell rings. The extension subscriber terminal 2 transmits forced transfer request information to an extension subscriber terminal 7 by operating the prescribed forced transfer requesting operation decided preliminarily. This forced transfer request information is detected by a transfer request detecting circuit 1, and the detected information is outputted to a forced transfer request informing circuit 3. The forced transfer request informing circuit 3 informs a central processing unit 4 that the extension subscriber terminal 2 requests the forced transfer to the extension subscriber terminal 7, and transfers the incoming call to the extension subscriber terminal 7. Thus, the incoming call can be transferred to either the extension or the line wire provided preliminarily without responding, by the easy forced transfer requesting operation of the subscriber at the time of the incoming call.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a call processing system for an electronic automatic switching system, and more particularly to a forced transfer system for incoming calls.

[Conventional technology]

Conventionally, this type of forced incoming call forwarding method, in which an incoming call to an extension subscriber is forwarded to a preset extension subscriber or external subscriber, has been used when the subscriber is absent, when the extension is busy, and when the extension is unanswered. It automatically forwards incoming calls, so you had to set in advance which forwarding settings you want to enable.

[Problem to be solved by the invention]

In the conventional forced forwarding method for incoming calls described above, when a subscriber is set to be absent, all incoming calls to that extension subscriber terminal are forwarded, and when the extension is set to busy, only incoming calls when the subscriber terminal is busy are forwarded. is forwarded, and when no-response is set, the incoming call is forwarded only after the no-response timing, so there was a drawback that incoming calls other than the set conditions were not forwarded. Furthermore, since the setting conditions differ depending on the content of the transfer, there is a drawback that setting errors or forgetting are likely to occur.

SUMMARY OF THE INVENTION An object of the present invention is to provide a forced transfer system for incoming calls that can be transferred to a preset extension or outside line without a response by a simple forced transfer request operation from a subscriber terminal when an incoming call is received.

[Means to solve the problem]

The incoming call forced forwarding method of the present invention is call forwarding.

In an electronic automatic switching system that has forwarding functions such as busy forwarding and no-answer forwarding, the forwarding destination of incoming calls to the subscriber terminal is registered in advance using a predetermined method from the extension subscriber terminal, and forced transfer request means for sending transfer request information for forcibly transferring an incoming call to the subscriber terminal to the pre-registered transfer destination; and transfer request information for detecting transfer request information output by the forced transfer request means. It has a detection means, and forced transfer notifying means for receiving the transfer request detection information outputted by the transfer request information detecting means and notifying the central processing unit of the electronic automatic exchange that the subscriber terminal has made a forced transfer request.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

FIG. 1 shows an extension subscriber terminal 2.7, a switch 6 for switching and connecting calls, a central office trunk 5, a central processing unit 4 for controlling call connections, and forced transfer of an extension subscriber terminal 2. A transfer request detection circuit 1 detects a request, and a central processing unit 4 receives transfer request detection information and detects a forced transfer request from an extension subscriber terminal 2.
It consists of a forced request notification circuit 3 and a central office line 8.

Here, the explanation will be given assuming that the extension subscriber terminal 2 calls the central processing unit 4 in advance by a predetermined method, and the transfer settings are registered in the extension subscriber terminal 7.

An incoming call from the central office line 8 is transferred to the central office trunk 8. It is connected to the extension subscriber terminal 2 via the switch 6, and a calling bell rings. The extension subscriber terminal 2 performs a predetermined forced transfer request operation (for example, pressing the #j button) in order to force transfer to the extension subscriber terminal 7, and sends forced transfer request information.This forced transfer request The information is detected by the transfer request detection circuit 1, and the detected information is output to the forced transfer request notification circuit 3. 0 The forced transfer request notification circuit 3 indicates that the extension subscriber terminal 2 has requested forced transfer to the extension subscriber terminal 7. Notify the central processing unit 4 of this. 0 The central processing unit 4 that received the forced transfer notification
transfers the incoming call to the extension subscriber terminal 7 using a known transfer process.

〔Effect of the invention〕

As explained above, the present invention has the advantage that when an incoming call is received, the call can be transferred to a preset extension or outside line without a response by the subscriber's simple forced transfer request operation.
