Abstract

PURPOSE:To respond to a call only from an arbitrary sepcific subscriber when a subscriber moves to a place other than his/her own seat where his/her own extension is installed, by performing the absence transfer service of only an incoming from a set second subscriber number to a transfer opposite subscriber number. CONSTITUTION:It is assumed that the subscriber number of an extension telephone 4b is registered as the transfer opposite subscriber number by an extension telephone 4a, and the subscriber number of an extension telephone 4c is registered as the second subscriber number. At this time, when the extension telephone 4a is called by an extension telephone 4d, a central control unit 2 checks whether a valid absence transfer opposite subscriber number is set in the absence transfer identification memory area 5 of the extension telephone 4a in an absence transfer opposite identification memory 3. When a call is issued from the extension telephone 4c to the extension telephone 4a, the absence transfer service is executed if the second subscriber number coincides with the subscriber number of the telephone 4c, that is a caller, and the call from the extension telephone 4c to the extension telephone 4a will not arrive at the extension telephone 4a, and it is transferred to and arrives at the extension telephone 4b, that is the transfer opposite subscriber number.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a call forwarding system in an electronic exchange that employs a storage program system, and more particularly to a call forwarding system that transfers only incoming calls from a specific telephone extension.

[Conventional technology]

Traditionally, electronic exchanges have been used to transfer calls to the first subscriber to the second subscriber's extension when the first subscriber leaves his or her desk and moves to the second subscriber's seat. provide services.

[Problem that the invention seeks to solve]

In the above-mentioned conventional electronic exchange, when a subscriber leaves his or her desk and moves to another subscriber's desk, he or she either abandons all calls to the extension telephone at his or her desk or uses the call forwarding service provided by the electronic exchange. I had to choose whether to transfer all calls to my own extension to the subscriber's extension at my destination. However, if a subscriber is absent from his or her desk without receiving the call forwarding service, there will be an inconvenience that the subscriber will not be able to respond to urgent calls that the subscriber expects to receive. When a subscriber receives calls, he or she can answer calls that require an emergency, but there is a drawback in that he or she must answer all calls that do not require an emergency at another subscriber's desk, which is not the subscriber's own desk.

SUMMARY OF THE INVENTION An object of the present invention is to provide a missed call transfer method that solves the above-mentioned conventional problems.

[Means for solving problems]

The call forwarding system of the present invention is provided in an electronic exchange that employs a storage program system, and includes a means for registering a call forwarding service using an extension telephone housed in the electronic exchange, and a means for registering a call forwarding service using an extension telephone housed in the electronic exchange; a means of configuring the settings;
Means for setting a second extension telephone number indicating a caller to whom the call forwarding service is to be implemented, and a forwarding service to the first extension telephone only for incoming calls from the set second extension telephone. The invention is characterized by having means for carrying out.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a relay system diagram and missed transfer identification memory showing an embodiment of the present invention.

The switch network 1 includes a plurality of extension telephones 4a, 4b, 4c.
+4d and is controlled by the central controller 2.

The central control device 2 has a missed call forwarding identification memory 3, and the missed call forwarding identifying memory 3 has a memory area 5 secured corresponding to each of the telephones a to 4d.

When call forwarding is registered by dialing on the extension telephone 4a, the central control device 2 stores the number of the extension of the call forwarding destination in the memory area 5 in the call forwarding identification memory 3 corresponding to the extension telephone 4a. , set '. Following the registration of call forwarding, an arbitrary second subscriber number 'N3 N2 N1N6' can be registered by dialing the extension telephone 4a. You can also choose not to register a second extension phone number by going on-hook after setting the call forwarding destination subscriber number, and if you do not register the second extension phone number, the conventional call forwarding service will be provided.

Extension telephone 4 as the transfer destination subscriber number by extension telephone 4a.
Suppose that the subscriber number of b is registered and the subscriber number of extension telephone 4C is registered as the second subscriber number.

At this time, when the extension telephone 4d makes a call to the extension telephone 4a, the central control unit 2 sets a valid call forwarding destination subscriber number in the call forwarding identification memory area 5 of the extension telephone 4a in the call forwarding identification memory 3. If valid data is not set, normal call processing is performed, but since valid data is now set, the call continues to call the second subscriber number 1N3N□N-N,'. and the caller's subscriber number.

Since the subscriber number of the extension telephone 4c is registered as the second subscriber number, it does not match the subscriber number of the extension telephone 4d that is the caller, and in this case, the call forwarding service is not implemented. Following normal call processing, the call arrives at extension telephone 4a.

On the other hand, when a call is made from extension telephone 4c to extension telephone 4a,
Since the second subscriber number 'N, N2N, N% and the subscriber number of the extension telephone 4c that is the caller match, the call forwarding service is implemented, and the call from the extension telephone 4c to the extension telephone 4a is The call was not received on extension telephone 4a, and the subscriber number to which it was forwarded was '''
T3T2T1T, the call is transferred to the extension telephone 4b corresponding to ', and the call is received.

When call forwarding is canceled by dialing the extension telephone 4a in the same manner as registration, the call forwarding identification memory area 5 corresponding to the extension telephone 4a in the call forwarding identification memory 3 is cleared to zero, and from now on, incoming calls to the extension telephone 4a will be cleared. follows normal call processing.

〔Effect of the invention〕

As explained above, the present invention provides an electronic switching system that employs a storage program system, by providing a call forwarding service to a forwarding destination subscriber number only for incoming calls from a set second subscriber number. When a person temporarily moves to a location other than his/her desk where his/her own extension is located, only calls from any specific subscriber can be forwarded and answered to the extension of the new subscriber that is set as the forwarding destination extension. On the other hand, calls from other specified subscribers do not need to be answered at the destination.

FIG. 1 is a diagram of a relay system of an electronic exchange that employs a storage program system according to the present invention, and an enlarged view of a missed transfer identification memory.
