Abstract

PURPOSE:To set the speech state of an incoming call at a side by which transfer registration is performed even when the transfer registration is performed by informing incoming to an incoming terminal on which transfer is set when outgoing is issued from an outgoing terminal, and transferring the incoming call to a transfer destination terminal. CONSTITUTION:When the outgoing is issued from the outgoing terminal B to the incoming terminal A, the incoming is informed by, for example, ringing, a buzzer, or display, etc., at the incoming terminal A. Also, at this time, since the transfer registration is performed on the transfer destination terminal C in advance at the incoming terminal A, the transfer destination terminal C receives the incoming and is rung. Therefore, the outgoing of the outgoing terminal B is transferred from the incoming terminal A, and is received by the transfer destination terminal C. At such transferred state, when a response operation is performed at the incoming terminal A, the incoming ringing of the transfer destination terminal C is stopped, and a speech state between the incoming terminal A and the outgoing terminal B is established. In such a way, it is possible to set the speech state at the side by which the transfer registration of the incoming call is performed even when the transfer registration is performed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a switching system in, for example, an electronic exchange.

(Conventional technology) With the development of an advanced information society, within various companies,
There is a demand for building a local communication system that can flexibly respond to requests for more sophisticated and diverse services.

An example of a service in this communication system is an automatic call transfer service.

With this automatic call forwarding service, once the user specifies the forwarding destination phone number by dialing, subsequent incoming calls are automatically forwarded to the forwarding destination.For example, an office call can be forwarded to someone outside the office. It is convenient for applications such as automatically forwarding calls to multiple locations, or automatically forwarding calls to multiple locations.

By the way, with this automatic call forwarding service, if you set the forwarding service and then forget about it, the incoming call will be automatically forwarded to the set forwarding destination even if someone is present at the time. There is a problem in that the transferred incoming call cannot be put into a talking state on the transfer setting side.

(Problems to be Solved by the Invention) As described above, in the above-mentioned switching system, there is a problem in that the transferred incoming call cannot be put into a talking state on the side that registered the transfer.

The present invention has been made in response to the above-mentioned problems, and an object of the present invention is to provide a switching system that allows a transferred incoming call to be put into a talking state on the side that has registered for transfer even if the transfer has not been registered. It is an object.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides an exchange system in which a call from a calling terminal is transferred from a receiving terminal to which a receiving terminal has been set for transfer to a forwarding destination terminal, when a calling occurs from the calling terminal. The incoming call is notified to the incoming call terminal set for transfer, and the incoming call is transferred to the forwarding destination terminal, and a call is established between the calling terminal and the receiving terminal or the calling terminal and the forwarding destination terminal by a predetermined operation. It is characterized by

(Function) In the present invention, when a call occurs from a calling terminal, the incoming call is notified to the receiving terminal that has been set to be forwarded, and the incoming call is transferred to the forwarding destination terminal. Establish a call between the terminal and the transfer destination terminal.

Therefore, even if there is no transfer registration, the transferred incoming call can be put into a conversation state on the side that registered the transfer.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1(a) and 1(b) are schematic diagrams for explaining the operation of a transfer service according to an embodiment of the switching system of the present invention.

In the figure, ASB and C are terminals, A is a receiving terminal that has registered for transfer, B is a calling terminal that makes a call to the person at the terminal, and C is a terminal to which terminal A is transferred.

Then, as shown in FIG. 1(a), when the calling terminal B makes a call to the receiving terminal A, the receiving terminal A receives the following information:
For example, the incoming call is notified by a ring, a buzzer, or a display. Also, at this time, in the terminating terminal recruitment, since the transfer has been registered for the transfer destination terminal C in advance, the transfer destination terminal C rings for an incoming call. Therefore, the call from the calling terminal B is transferred from the receiving terminal A and is received at the transfer destination terminal C.

Then, in this transferred state, as shown in FIG. 1(b), when a response operation is performed at the receiving terminal A,
The incoming call ringing of the transfer destination terminal C is stopped, and a call state between the receiving terminal A and the calling terminal B is established.

Next, the processing operations in the exchange that performs the above-mentioned transfer service will be explained using the flowchart shown in FIG.

First, when a call is made from calling terminal B to receiving terminal A (step 201), calling terminal B
The information (such as the extension number or outside line number of terminal B) is recorded in the memory (step 202), and the receiving end is notified of the incoming call by, for example, a ring, a buzzer, or a display (step 203). The call is transferred to the transfer destination terminal C, and the terminal C rings (step 204). After this, it is confirmed whether terminal A responds (step 205) or terminal C responds (step 206).

If terminal A performs a response operation, the information about terminal B is obtained by referring to the caller data registered in the memory, and the incoming call ringing of terminal C is stopped (step 207).
A call is established between terminal A and terminal B (step 208)
.

In addition, in steps 205 and 206, if the transfer destination terminal C responds before the terminal A responds, the information that the terminal B and the terminal C are in a call is additionally recorded in the information of the calling terminal B in the memory ( Step 209). After this, it is confirmed whether terminal A responds (step 210), and when terminal A performs a response operation, the information on terminal B shows that terminal B and terminal C are currently talking, so terminal A is notified that A responds, for example, by tone, display, etc. (step 211). Then, whether terminal C disconnects (step 212
), it is confirmed whether terminal B disconnects (step 213), and if terminal C disconnects here, the call between terminal A and terminal B is established (step 208). Also, when terminal B disconnects, the information in the memory is cleared (step 2).
14), the end of the episode.

Note that the response operation in the above-mentioned operation can be a specific key operation in the case of a multi-function digital telephone, or by dialing a special number in the case of a standard telephone.

In addition to automatic call transfer services, the present invention can be used in response delay transfer services that transfer calls when there is no response after a certain period of time has passed since the call was received.

Therefore, in this embodiment, it is possible to very easily return a transferred call to the user and make the call. Furthermore, by recording information about transferred calls, it is possible to easily respond not only from the transfer registration terminal but also from other terminals.

[Effects of the Invention] As explained above, in the switching system of the present invention, it is possible to put a transferred incoming call into a talking state on the side that registered the transfer even if the transfer is not registered.
