Abstract

PURPOSE:To receive a specific important phone call by applying registration rejecting an incoming call of an extension telephone set, registering a 2nd special number and an incoming allowable extension number and connecting the extension only with the arrival of an incoming from the incoming allowable extension telephone set. CONSTITUTION:When an extension telephone set 1 is hooked off, an incoming rejection setting special number is dialed and the handset is hooked on, the telephone set 1 reaches the incoming rejection state. When the telephone set 1 is hooked off, the incoming allowable extension registration special number is dialed and the number of the extension telephone set 2 allowing the incoming call succeedingly, the central controller 8 writes the accommodation information of the telephone set 2 to the memory corresponding to the accommodated location of the telephone set 1 in the storage device 9. The controller 8 sends a call tone to the telephone set 2 and sends ringing to the telephone set 1. When the telephone set 1 replies, the talking between the telephone sets 1, 2 is enabled. Thus, a specific important phone call is accepted.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a call rejection system in an electronic automatic private branch exchange.

(Prior art) In the conventional call rejection service system, once a call is set to be rejected from a certain telephone extension, all M calls to that telephone extension are rejected until the call is set to be rejected. That was common.

(The problem that the invention seeks to solve I!a) The conventional method of delivery (M-rejection service) mentioned above is as follows.

For example, if you set an incoming call deduction because you want to concentrate on work or have a meeting at your desk, all incoming calls to the set extension phone will be rejected. Therefore, you should restrict calls for important matters that you know you will receive, calls from your boss, and even some calls that you do not want to reject.

Therefore, even if you register to reject one call, if you receive an incoming call from some specific person, it may be possible to connect the incoming call only to that specific person. One such technique is Japanese Patent Application No. 1983-99749 (filing date: April 22, 1982).
).

The object of the present invention is to provide a registration operation procedure different from that of the above-mentioned Japanese Patent Application No. 63-99749.

The object of the present invention is to provide an incoming call rejection method in which first, all registrations are performed to reject the first call, and then an extension number to which incoming calls are permitted to be registered is registered.

(Means for Solving All Problems) In order to achieve the above-mentioned object, the call rejection method according to the present invention is to dial all the special numbers set for incoming call rejection from an extension telephone, and thereafter send the extension to the terminal. In electronic automatic private branch exchanges that are equipped with a call rejection service that allows you to reject incoming calls, the system stores not only call rejection information but also information about the number of accepted extensions in the area corresponding to the location of each extension. When the extension phone is off-hook and the special number set to reject calls is dialed,
When all the incoming call rejection information is stored in the area corresponding to the extension telephone housing position of the storage device, and once on-hook, the user goes off-hook again and dials all the special numbers of FI2, and then dials the incoming call permission extension number. The incoming call allowed extension is stored in the same area where the incoming call rejection information is stored, and only incoming calls from the incoming (FI allowed, %!) telephones are connected.

(Example) The present invention will be described in more detail below with reference to one drawing.

FIG. 1 is a block diagram showing an embodiment of the IY5 rejection method according to the present invention.

Extension phone 1. Extension telephone 2 and extension telephone 3 are accommodated in main switch 7 via subscriber circuits 1.2 and 3. The central control unit 81 is connected to the memory unit 9, the main switch 7 and the power saving circuit 4°5.6.

This embodiment describes only the parts directly related to the present invention, and in the following explanation, all extension telephones 1 are called calling extensions, and extension filling machines 2 and 3 are called extensions A and B, respectively.

First, when the operator of the internal i-telephone 1 takes the extension phone 1 off-hook, dials the special number tone for incoming call rejection, and goes on-hook, the extension phone 1 enters the incoming call-rejecting state. Incoming calls to extension telephone 1 from all extension telephones including 2.3 are rejected, and a restriction tone is sent from the exchange to the calling party's extension.

This incoming call rejection information is stored in the area of the storage device 9 corresponding to the location where the extension telephone 1 is accommodated.

In this state, the operator of extension telephone 1 turns off extension telephone 1, dials the special number for extension registration for call permission, and then dials the extension telephone number 20 for permitting call-in, and central controller 8 The accommodation position information sound 1 of the extension telephone 2 is written into the memory corresponding to the accommodation position of the extension telephone 1 in the telephone 9.

Thereafter, when the extension telephone 1 goes on-hook, the registration of the extension telephone that is allowed to receive calls is completed.

Next, extension number 2 goes off-hook, and the extension number is changed to number 1? When the dial is dialed, the central control unit 8 fully identifies that the extension telephone 1 is the incoming call rejection information, and refers to the memory corresponding to the housing position of the extension telephone 1 in the compartment 9 of the note 41n, and sets the extension telephone 2 on the calling side 1. It is determined whether incoming calls to extension 1 and packing machine 1 are permitted.

Since the extension telephone 2 is permitted to receive calls to the extension telephone 1 due to the registration described in in, the central control unit 8 sends a pre-ring tone to the extension telephone 2 and a ringing sound to the extension ML telephone.

If extension telephone 1 answers, extension telephone 1 and extension telephone 2
You will be able to talk to.

When the extension telephone 3 goes off-hook and the number of the extension telephone L is dialed, the central control unit 8 determines that the extension telephone 1 is in the incoming call rejection state by f'Jk, and stores the extension telephone 1 in the storing position in the storage device 9. Referring to the corresponding memory, since the extension telephone 3 is not permitted to receive calls to the extension telephone L, the central control unit 8 sends a restriction tone to the extension telephone 31 and rejects the incoming call to the extension telephone 1. .

When the extension telephone 1 goes off-hook and dials the special number for canceling call rejection, the central control unit 8 sends the extension telephone 10
The incoming call rejection state is canceled, the memory corresponding to the extension telephone 1 housing position in the recording device 9 is cleared, and the incoming call rejection service is terminated.

(Effect of the invention) As described above, according to the present invention, first.

After completing all registrations to reject the charge on the extension phone, go on-hook, go back on-hook and register all the second special numbers and extension numbers allowed for incoming calls, and only accept calls when there is an incoming call from the extension phone. It provides a method. Therefore, when you want to concentrate on work or have a meeting at your desk? This has the effect of allowing you to receive certain important calls even if you set all calls to be rejected.
