DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a representative selection method for an extension terminal which selects a representative when the extension terminal accommodated in a private branch exchange receives a call and is busy.

[0002]

2. Description of the Related Art Conventionally, when an extension terminal accommodated in a private branch exchange receives a call and is busy, the extension terminal is registered in a predetermined representative group and determined for each representative group. The representative selection method was used.

[0003]

However, in the above-described conventional selection method, since the representative format is determined for each representative group, the extension terminals registered in any one group can extend over other groups. There was a problem that I could not register. Also, depending on the representative type, the extension terminal that performs representative selection is fixed,
There was also the problem of lack of flexibility.

SUMMARY OF THE INVENTION It is an object of the present invention to determine the presence / absence of representative selection for each extension terminal, the number of destinations to be selected, and the destination extension terminal, so that representatives of extension terminals capable of freely performing representative selection for each extension terminal. It is to provide a selection method.

[0005]

In order to achieve the above object, in a private branch exchange accommodating a plurality of extension terminals, when an arbitrary extension terminal is received and the extension terminal is busy. A representative selection method for receiving a call to another predetermined extension terminal, wherein, for each of the plurality of extension terminals, the number of times of representative selection and the selected extension terminal to be the next destination are determined. storage means for storing information indicating when the inner wire terminal coming into the first was busy, referring to the storage means, the extension terminal coming into the first
It extracts a selected number of representative selection against, the extraction
Selection control means for performing incoming call control on the selected extension terminal by determining the representative selection only for the selected number of times, and performing busy control when it is determined that there is no extracted number of selections. I do.

[0006]

Therefore, according to the present invention, it is possible to determine the presence / absence of representative selection for each extension terminal, determine the number of incoming calls and the destination extension terminal, and freely perform representative selection for each extension terminal. .

[0007]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a system configuration diagram of a private branch exchange and an extension terminal connected to the private branch exchange in this embodiment.

In FIG. 1, reference numeral 100 denotes a private branch exchange. The private branch exchange 100 includes a communication path switch 101 for forming a call with various terminals, and a private branch exchange 1.
And a storage device 103 for storing various programs such as an exchange operation control program, station data, and various tables, and a plurality (for example, n
) Extension terminals 104 (104A, 104B...).

[0010] FIG. 2 is a diagram for managing the number of representative selections registered for each extension terminal 104 and the extension to be called.
2 shows a configuration example of a memory area 200 of control data stored in a storage device 103. This control data memory area 200 is an n block for managing n extension terminals that can be accommodated in the private branch exchange 100, with the number of representative selections and the extension to be called as one block 201 for each extension terminal 104. It is composed of

Next, the operation of the embodiment configured as described above will be described.

FIG. 3 is a flowchart showing the procedure for representative selection when the extension terminal 104A is called and busy.

In step 301, the extension terminal 104A
Is determined to be busy. If empty, step 30
7 to call the extension. Step 30 if busy
Transition to 2.

In step 302, the number of representative selections for the extension terminal 104A is extracted with reference to the memory 201. If the number is 0, it is determined that there is no representative selection, and the process proceeds to step 308 to transmit a busy tone. If the number is not 0, the process proceeds to Step 303.

In step 303, the extension terminal 104B to be the extension to be called is extracted, and the process proceeds to step 304.

In step 304, it is determined whether the extension terminal 104B to be called is callable. If the call is permitted, the process proceeds to step 309 to call the extension. If the call cannot be made, the process proceeds to step 305.

In step 305, "1" is subtracted from the number of representative selections extracted in step 302, and if the result is 0, the process proceeds to step 310 to transmit a busy tone. 0
Otherwise, the process proceeds to step 306.

In step 306, the extension to be called by the extension terminal 104B is extracted by referring to the memory 201. If there is no registration, the process proceeds to step 311.
Sends busy tone. If there is a registration, step 304
And the same processing as described above is performed to perform representative selection.

FIG. 4 to FIG. 7 are diagrams showing the configuration according to the representative selection method.

FIG. 4 shows the memory contents of the representative selection method for extension A. In the memory 400, the representative selection count = 2
Indicates that the call extension is extension B.

FIG. 5 shows the memory contents of the representative selection method for extension B. In the memory 500, the representative selection count = 2
Indicates that the calling extension is extension C.

FIG. 6 shows the memory contents of the representative selection method for extension C. In the memory 600, the representative selection count = 0
Indicates that the call extension is extension D.

FIG. 7 shows the contents of the memory of the representative selection system of the extension D. In the memory 700, the representative selection count = 1
Indicates that the call extension is extension B.

FIG. 8 is a flowchart showing a process of selecting a representative of the extension A. When an incoming call is received at extension A and the telephone is busy, the number of representative selections = 2 and extension B are extracted from the memory 400 as the calling extension. Then, if the extension B can be called, the extension B is called. When the extension B cannot be called, since the number of times of the representative selection is 2, the extension C is extracted from the memory 500 as the calling extension. If the extension C is callable, the extension C is called. When the extension C cannot be called, the representative selection is ended because the number of times of representative selection is two.

FIG. 9 is a flowchart showing a process of selecting the extension B as a representative. If there is an incoming call at extension B and the line is busy, the number of representative selections = 2 and extension C are extracted from the memory 500 as the calling extension. If the extension C is callable, the extension C is called. If the extension C cannot be called, the representative number of selections is 2, so that the extension D is extracted from the memory 600 as a call extension. Then, if the extension D can be called, the extension D is called. If the extension D cannot be called, the representative selection is ended because the number of representative selections is two.

FIG. 10 is a flowchart showing a process of selecting the extension C as a representative. If there is an incoming call at extension C and it is busy, the representative selection count = 0 is extracted from the memory 600. In this case, the representative selection is not performed because the representative selection count is 0.

FIG. 11 is a flow chart showing a process for selecting a representative of the extension D. If an incoming call is received at extension D and the telephone is busy, the number of representative selections = 1 and extension B are extracted from memory 700 as a calling extension. Then, if the extension B can be called, the extension B is called. If extension B is call not, since the upper SL representative selected number is 1, and ends the representative selection.

As described above, according to the present invention, the presence / absence of representative selection and the number of times of selection are determined by the extension terminal that has arrived first, and the next selected extension terminal is determined corresponding to the extension terminal. The representative selection method becomes possible.

[0029]

As described above, according to the present invention, for each of the extension terminals accommodated in the private branch exchange, the presence or absence of representative selection during busy, the number of representative selections, and the extension terminal to be selected. Can be determined, and a flexible representative selection method can be provided.
