DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic exchange using a multi-appearance function, and more particularly to an electronic exchange in which a ringing telephone can be changed from the nearest extension telephone.

[0002]

2. Description of the Related Art In recent years, electronic exchanges have become centralized in control by means of a processor, and have become intelligent, capable of performing complex and sophisticated control, and can provide various services. As one of the services, there is a function in which a plurality of telephones have the same extension number, and when the extension telephone number receives a call, any one of the plurality of telephones can answer. This function is called a multi-appearance group, and the group to which the plurality of telephones belong is called a multi-appearance group.

A conventional electronic exchange having such a multi-appearance group, when receiving a call to the multi-appearance group, rings a telephone designated to be ringed in advance.

[0004] On the other hand, there are many cases in which there are no people around depending on the time zone, and even in such a case, if there is an incoming call in the multi-appearance group, the telephone in the unmanned room may ring. , A phone that has no people nearby will ring. And even if there is a person who can respond in another room, this cannot be known, which is a problem in service.

[0005]

As described above, in a conventional electronic exchange system having a multi-appearance function, when a call arrives in a multi-appearance group, a telephone set to be ringed in advance is made to ring.

[0006] The setting registration of the ringing telephone in the multi-appearance group is performed by performing an editing operation such as data registration / deletion from a maintenance terminal connected to the electronic exchange. It cannot be changed easily, so even if a certain multi-appearance group knows that no one is around by time of day, if there is an incoming call in that multi-appearance group, the call will be sent to the phone that has been designated to ring in advance. On the other hand, there is a problem that the ringing is controlled, and the incoming call is not noticed.

Therefore, an object of the present invention is to make it possible to change the ringing telephone set for an incoming call into a group from any telephone set in the multi-appearance group, so that the incoming call can be made to a telephone set having no neighbors. It is therefore an object of the present invention to provide an electronic exchange in which the response probability can be improved and the service can be improved by preventing the caller from keeping waiting.

[0008]

In order to achieve the above object, the present invention is configured as follows. That is, an extension group that can respond to incoming calls for a plurality of extensions is set, and for incoming calls to the extension group, an electronic exchange configured to ring a connection telephone of a preset extension is used for the extension. Storage means for holding registration information for sound designation for each extension belonging to the group;
When input information is received from a telephone in the extension group by a predetermined input operation, a change mode is set. When an extension telephone number information is received in this mode, a corresponding ringing designation of the extension telephone number in the storage unit is received for each operation. A setting change function for alternately canceling registration / setting change control and a ringing control for performing ringing control on an extension for which ringing designation has been registered by referring to ringing designation registration information in the storage means when an incoming call arrives at the extension group. And control means having functions.

[0009]

In such a configuration, the storage means holds ringing designation information for each extension belonging to the extension group, and when a predetermined input operation is performed by a telephone in the extension group, the control means is controlled. Is set to the change mode at the stage of receiving the input information by the input operation from the telephone, and when the extension telephone number information is received in the mode, registration of the corresponding ringing designation of the extension telephone number in the storage means is performed for each operation. Release / setting change control is performed alternately. When there is an incoming call to the extension group, the control unit refers to the ringing designation registration information in the storage unit and performs ringing control on the extension for which the ringing designation has been registered.

In this manner, the registration information of the ringing designation for each extension belonging to the extension group is stored in the storage means, and the registration information of the ringing designation is a predetermined input operation and an extension telephone number from a telephone in the extension group. Since the ringing designation registration and cancellation can be alternately performed for each operation by the input operation of, the ringing designation change of any extension can be performed from any telephone.
The phone to be ringed can be changed from any phone, the phone to be ringed can be changed freely, incoming calls can always be handled according to the situation, and phones without people nearby can be changed. It is possible to provide an electronic exchange in which ringing is prevented, the response probability is improved, and the service can be improved.

[0011]

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

FIG. 1 is a schematic configuration diagram of an exchange system according to an embodiment of the present invention. In the figure, reference numeral 10 denotes an electronic exchange, which performs an exchange operation between an extension and an outside line and between extensions, and also has a multi-appearance function. Reference numeral 11 denotes a central control unit, which plays a central role in controlling the electronic exchange 10.

The central control unit 11 executes these controls by executing a control program, and can manage ringing of a ringing telephone in response to an incoming call. Also, 1
Reference numeral 2 denotes a storage unit. The storage unit 12 is used for holding various tables and a working area in addition to a control program. 21a to 21f are extension telephones connected to the electronic exchange 10, and are multifunctional telephones.

As shown in the figure, the present system has a configuration in which an electronic exchange 10 accommodates a plurality of multifunctional telephones 21a to 21f. These multi-function telephones 21a to 21f are, in order, extension numbers 200, 210, 220, 251, 252, and 2
It is assumed that 53 has been assigned, and these constitute a multi-appearance group MG with a group extension number of 200.

The electronic exchange 10 is controlled by a central control unit 11 which controls switching and transmission / reception of a telephone. The storage unit 12 has a table (ringing designation information table) for registering a designated ringing extension. Here, in addition to the registration of the telephones belonging to the multi-appearance group and the information of telephones to be ringed in response to an incoming call to the group, the electronic exchange has the necessary functions.

That is, in the present system, the exchange accommodates a plurality of multifunctional telephones.
Reference numeral 0 denotes exchange control and transmission / reception control of the telephones 21a to 21f performed by the central control unit 11, and the storage unit 12 holds group registration (registration of telephones belonging to a multi-appearance group) and ringing designation telephone setting information. In addition, it has functions required for an electronic exchange.

The multi-function telephones 21a to 21f are grouped as a multi-appearance group MG, and have a function of allowing any telephone in the group to answer when a call arrives in the multi-appearance group MG.

FIG. 2 is a sound designation information table showing the sound designation information in each group held in the storage unit 12 of the electronic exchange 10. This ringing designation table holds registration information of telephones to be ringed in each group.

The structure of the sound designation information table will be described. In the case of FIG. 2, the extension numbers of telephones grouped for each group extension number (this telephone number is assumed to be unique to each telephone) and the port number to which the telephone is connected (input / output port No .: I / O port number) and extension number information are registered.

Then, for the telephone to be ringed, a flag is set in a ring designation section corresponding to each extension number. That is, the flag of the item designated to sound is turned on. On the other hand, this item is turned off for telephones that do not ring.

In the example shown in FIG. 2, among the telephones in the group sharing the extension number 200, the telephones connected to the port numbers P6 and P8 (extension numbers 200 and 220) have the ringing designation flag turned on. When a group receives an incoming call, these two units ring. Other telephones can answer, but will not ring.

Next, a method of changing the ringing designation will be described.
A description will be given of an example in which a call is made to a telephone in the same group. By operating a predetermined special number or a function key from any telephone in the multi-appearance group MG, it informs the electronic exchange (PBX) that this input procedure relates to a change in the setting of ringing designation. And
Press the key with the same group extension as the phone you want to change,
Thereafter, the user inputs the extension number to be changed.

By the above operation, the central control unit 11 of the electronic exchange 10 controls the ringing designation flag of the telephone in the ringing designation information table of the storage unit 12 to be inverted. Thus, if the sound is designated (flag on) before the operation, the sound designation is canceled by this procedure (flag off). Conversely, if the sound is not designated before (if the flag is off), the sound is designated by this procedure (flag on). Can be done. Hereinafter, the method of changing the ringing designation will be described in detail by taking the multi-appearance group of FIG. 1 as an example.

It is assumed that the multi-appearance group MG shown in FIG. 1 has a ringing designation as shown in FIG. At this time, when there is an incoming call to the l-group extension number 200, the central control unit 11 refers to the ringing designation information table and knows that the extension numbers 200 and 220 are ringing-designated telephones.

Then, the central control unit 11 has the extension number 200
Knowing the connected port number of the telephones No. 220 and No. 220, a ringing signal is transmitted to this port to perform ringing control. As a result, a ringer tone is sent to the telephone connected to the port, and the telephones with the extension numbers 200 and 220 ring.

Next, when the ringing designation is changed, for example, it is assumed that the ringing designation of the telephone having the extension number 220 is canceled and the setting is changed so that the telephone having the extension number "252" is ringed.

First, a special number or a function key for changing the sound designation is input from any of the telephones belonging to the multi-appearance group MG. Then, the user presses the key of the group extension number "200", and then inputs the extension number "220" to be changed.

As a result, the central control unit 11 stores in the storage unit 12
Is controlled in the ringing designation information table of FIG. 2 formed in the storage unit 12 by inverting the ringing designation flag of extension number 220. As a result, the ringing designation of the extension number is canceled.

Then, after inputting the special number or the function key again, the key of the group extension number "200" is pressed, and the extension number "252" to be changed is inputted. With this, the central control unit 11 sets the
Since the ringing designation flag of the extension number "200" is inverted, the ringing designation of the telephone having the telephone number is set.

As a result of the above operation, the extension numbers "200" and "252" are designated as ringing. Therefore, when a call arrives at the group extension number "200", the extension number "20" is set.
The "0" and "252" telephones will ring.

The above control is shown in a flowchart as shown in FIG. Briefly describing this, first, a special number or a function key for changing the ringing designation is input from any of the telephones belonging to the multi-appearance group MG (st1).

Then, the central control unit 11 checks the input contents (st2), and if it is a predetermined key input, it waits for a group extension number input. After the group extension number is inputted, the extension number is inputted ( (st3a, stb), it is checked whether it is an extension number in the multi-appearance group in the ringing designation information table of FIG. 2 formed in the storage unit 12 (st4), and if it is an extension number in the multi-appearance group, If the flag of the corresponding extension number is inverted
(st5).

As a result, the ringing designation flag of the extension number to be changed is inverted, so that if the ringing designation of the extension number has been set, the ringing designation is reset and the ringing designation is canceled. In this case, the ringing designation is registered. Then, the process returns to st1. If it is not a predetermined key input in st2, the process proceeds to a normal telephone process (st6).

As described above in detail, according to the present invention, the data for specifying the ringing can be changed by accessing from any telephone, so that the user can use the data without using the data setting terminal device. The ringing telephone can be flexibly changed by the user's own simple operation from the extension telephone according to the state.

In this way, the registration information of the ringing designation for each extension belonging to the extension group is stored in the storage means, and for an incoming call to the group, the extension telephone for which the ringing designation is made based on the registration information is made. In addition to controlling to ring, the registration information of the ringing designation is controlled to alternately register and cancel the ringing designation for each of these operations by inputting a predetermined operation from a telephone in the extension group and inputting an extension telephone number. With this configuration, it is possible to change the ringing designation of any extension from any telephone, so that the user can change the telephone to be ringed more easily than any telephone. Phone can be changed freely and easily, and it is possible to always respond to incoming calls according to the situation. It is possible to prevent that causes sounding the no telephone, aims to improve the response probability, it is possible to improve the service Te following. The present invention is not limited to the embodiment described above and shown in the drawings, and can be implemented with appropriate modifications without departing from the scope of the invention.
