Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a centralized extension call reception control system in an electronic private branch exchange.

A known function of electronic private branch exchanges is a so-called pick-up function in which a nearby extension responds to a call received at an absent extension by dialing a special number. In this type of pick-up function, it is necessary for the extension to answer to dial the special number each time a response is made, which is inconvenient in operation. Furthermore, the above-mentioned pick-up function is not necessarily effective when calls arriving at a plurality of predetermined extensions (hereinafter referred to as an extension group) are centrally managed by a specific extension within the extension group.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the drawbacks of the conventional pick-up function as described above, and to realize a means by which a particular extension can respond to a call arriving at a group of extensions without requiring special operations. This purpose is to provide an electronic private branch exchange with a belonging extension group registration means for making a plurality of extensions belong to the same extension group; a response extension registration stage for registering one extension belonging to the extension group as a response extension registration; a calling source analysis means for analyzing whether or not the calling source of a call arriving at an extension belonging to the extension group is an extension belonging to the extension group in a state where a response extension is registered; waiting call receiving means for arranging incoming calls for which the means has determined that the caller is from an extension other than the extension belonging to the extension group in a response queue provided corresponding to the response extension; This is accomplished by arranging calls to the answering extension in the order of arrival.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing an extension centralized call response control system according to an embodiment of the present invention. In the figure, extensions A, B, and C accommodated in the electronic private branch exchange constitute extension group G1, and extension D constitutes another extension group G2.
belongs to. The main storage device MM has an extension group area M1 corresponding to each extension A, B, C, and D accommodated.
is provided, and the identification code g1 or g2 of the extension group G1 or G2 to which each extension belongs is stored. The identification code g1 or g2 is input together with a predetermined command from a maintenance input/output device (not shown),
It is stored in a known manner. The main storage device MM is also provided with a registration area M3 corresponding to each extension group G1 and G2, in which a logical value of 0 is stored unless a registration operation to be described later is performed. In such a state, extension D makes a call to connect to extension B, and after being connected to the calling register trunk ORT via route 1 in the network NW in a known manner, extension B
By dialing the telephone number of the central control unit CC
uses a well-known internal processing process to obtain the accommodation location information of calling extension D on the network NW and the called extension B.
The telephone number information is sent to the extension number translation unit C1. After converting the received telephone number information into accommodation location information, the extension number translation unit C1 sends the accommodation location information of extensions D and B to the service execution control unit C2. The service execution control unit C2 that received the storage location information,
Calling extension identification section C21 and called extension identification section C2
2, the extension group identification information g2 of the calling extension D and the extension group identification information g1 of the called extension B are extracted from the extension group area M1 in the main storage device MM, and the comparison unit C
23, the extension group identification information g1 and g2 are compared, and the registration identification section C24 compares the extension group identification information g1 and g2.
A logical value 0 corresponding to the extension group identification information g1 of the called extension B is extracted from the registration area M3 in the MM. The comparison unit C23 outputs a logical value 1 because the extension group identification information g1 and g2 are different as a result of the comparison,
Further, since the registration identification unit C24 outputs the logical value 0 extracted from the registration area M3, the service execution control unit C2 outputs the logical value 0 through the gate C25.
41 and C42. As a result, the extension centralized call response control unit C3 is not activated, but the general call reception control unit C4 is activated, checks whether the called extension B is blocked using a known method, and if it is blocked, performs busy processing. If the extension is idle, the connection process is executed, and after calling the called extension B, it is connected to the calling extension D via the internal trunk IOT and routes 2 and 3 in the network NW. Next, in order to implement an extension centralized answering service in which calls arriving at extension group G1 are answered by a specific extension C, extension A with predetermined qualifications makes a call, and a predetermined special number (for example, 112 ) and the telephone number of extension C, the central controller CC detects the qualifications and special number 112 of the calling extension A using a known method, and determines that the registration operation for the centralized extension response service for extension group G1 has been performed. Then, the extension group identification information g1 corresponding to extension C is extracted from the extension group area M1 in the main storage device MM, and the logic is stored in the extension C corresponding section of the response extension area M2 provided corresponding to each extension. Stores the value 1. Note that the response extension area M2 stores all logical values of 0 unless a registration operation is performed. Furthermore, the central controller CC is connected to the main memory MM.
Registration area M corresponding to extension group identification information g1 in
A logical value of 1 is stored in 3. In such a state, when extension D makes a call to connect to extension B and dials the telephone number of extension B, the central controller CC sends a call from the extension number translation unit C1 to the service execution control unit in the same process as described above. C2 is made to transmit the accommodation position information of extensions D and B. The service execution control unit C2 also extracts the extension group identification information g2 by the calling group identification unit C21 and the extension group identification information g1 by the called group identification unit C22 in the same process as described above, and performs a comparison by the comparison unit C23. The logical value 1 is output as a result, and the logical value 1 is extracted from the registration area M3 corresponding to the extension group identification information g1 by the registration identification section C24 and output.
As a result, the service execution control unit C2
5 to logic 1 through gates C41 and C42
send to As a result, the general incoming call control unit C4 is not activated, but the extension intensive incoming call response control unit C3 is activated. The extension centralized incoming call response control C3 is executed by the response extension determination unit C31 to store the extension group area M in the main storage device MM.
1, the extension group identification information g1 extracted by the service execution control unit C2 is stored, and the response extension area M2 stores the logical value 1.
The incoming call from extension D is connected to the incoming call queue C32. Note that the ringing tone is sent to the calling extension D from the trunk IOT within the local office connected via path 2 within the network NW. On the other hand, the extension intensive incoming call response control unit C3 periodically monitors the idle state of the extension C whose logical value 1 is stored in the response extension area M2 in the main storage device MM by means of the response extension idle monitoring unit C33. If a free state is detected, the first call is extracted from the corresponding queue C32, and the central control unit
Let CC perform the known connection process. When the call from extension D to extension B comes in its turn and is extracted from the queue C32, the central controller CC causes extension C to ring and then establishes route 4 within the network NW. Extension C responds to calling extension D via its own intra-office trunk IOT and routes 2 and 4 within network NW. If the calling extension D abandons the call before the extension C answers, the extension centralized call reception control C3 causes the central controller CC to execute the process of releasing the abandoned call using a known method. Note that in the case of a call between extensions belonging to extension group G1, the extension group identification codes of the calling and called extensions extracted by the service execution control unit C2 in the above process are both g1, so the comparing unit C23 Logic 0 is output from the call extension, and the general call termination control section C4 is activated to terminate the call to the selected called extension regardless of whether it is registered or not.

As is clear from the above description, according to the present embodiment, when extension A with predetermined qualifications performs a predetermined registration operation, calls arriving at extension group G1 are placed in the queue for specific extension C. C32, the extension C is called sequentially as long as there are calls in the queue C32, and the extension C can respond to the calls without performing any special operations.

Note that the figure is only one embodiment of the present invention.
For example, the extension group identification code g for the extension group area M1
The inputs of 1 and g2 are not limited to those made from the maintenance input/output device; for example, extension A
At the time of registration operation, extension A, which constitutes extension group G1,
Although input by dialing the telephone numbers B and C is also considered, the effects of the present invention do not change in such a case. Furthermore, the extension C that centrally responds to calls arriving at extension group G1 is not limited to the one specified by extension A during the registration operation, and it may be considered to specify it in advance from the maintenance input/output device. Even in such a case, the effects of the present invention remain unchanged.
In some cases, it may be considered that calls between extensions belonging to extension group G1 are also collectively received on extension C, but the present invention functions in relation to the incoming extensions, and does not apply to the originating line. Since it does not depend, the effect of the present invention does not change even in such a case. In addition, caller D is not limited to receiving calls from extensions accommodated in the electronic private branch exchange, but may also receive incoming calls from relay stations accommodated in the same exchange, or even from other exchanges; however, in such cases, However, the effect of the present invention remains unchanged. Furthermore, the sound to be sent in response to an incoming call connected to the queue C32 is not limited to a ringtone; for example, it is also possible to hear a talkie sound, but the effects of the present invention can also be achieved in such a case. remains unchanged. Furthermore, each control mechanism included in the central controller CC may be realized by a program, but the effects of the present invention will not change in such a case. It goes without saying that the number of extensions accommodated in the electronic private branch exchange and the configuration of the extension group are not limited to those shown in the drawings.

As described above, according to the present invention, when an extension with predetermined qualifications performs a registration operation in an electronic private branch exchange, incoming calls to an extension group are queued to a specific extension within the extension group. By centrally receiving calls, it becomes possible for the specified extension to respond to the incoming calls in sequence without performing any special operations.
