DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a private branch exchange (PBX) and, more particularly, to a method for notifying a false facsimile incoming call of an incoming call.

[0002]

2. Description of the Related Art Conventionally, in a PBX, an extension telephone is accommodated and a facsimile is also accommodated in an extension circuit.
It is common practice to use a direct extension connection.

However, if a facsimile call from the network is erroneously connected to the extension telephone due to a difference in the number, there is no means for the extension person to respond by himself, and the facsimile error call is received until the other party notices the difference in the number. There was an annoyance.

In a PBX having a function of receiving a telephone number of a caller when receiving a call from a network and displaying the caller number on a number display of an extension telephone to be connected,
Since the device telephone number of the originating facsimile can be confirmed at the time of an erroneous call, a method of notifying that an error has occurred from another facsimile later can be adopted, but this method requires an expensive extension telephone. However, the function of displaying the caller ID is not widely used in all PBX extension telephones.

[0005] On the other hand, some facsimile apparatuses have a function of telling their contact telephone numbers by voice when automatically determining that the wrong destination is a voice terminal. , Also expensive and not widespread. That is, as this kind of prior art, for example, Japanese Patent Laid-Open Publication No. Hei 6-169382 discloses that when a facsimile transmission device erroneously makes a call to a non-facsimile terminal such as a telephone terminal and receives a call to the other party, that fact is transmitted. After the link is established, the facsimile transmission device, which is a terminal, can be notified by the other party that made a false call. There has been proposed an apparatus that knows that a telephone terminal has arrived and sends a message to a person on the other side to take a countermeasure. Japanese Unexamined Patent Publication No. 5-130359 discloses an apparatus for preventing a facsimile apparatus with an automatic transmission function from being erroneously connected to a general subscriber's telephone set by the automatic transmission function. In such a case, a method has been proposed in which fixed voice information and contact telephone number information are reproduced as a voice message so that the connection telephone number can be known in addition to an incorrect connection.

[0006]

As described above, the first problem of the prior art is that a facsimile erroneous incoming call to a PBX extension can be easily and inexpensively notified to the originating facsimile. There is no.

[0007] The reason is that the means for notifying the extension person of the telephone number of the other party is expensive.

[0008] A second problem of the prior art is that even if a telephone number is found, a facsimile reply is made manually, and the operation is complicated.

The reason is that there is no means for automatically coordinating the other party's telephone number information, the reply facsimile, and the reply message.

[0010] Accordingly, the present invention has been made in view of the above circumstances, and has as its object to automatically receive an erroneous facsimile call from a network to a PBX extension by a simple operation of an extension person. Another object of the present invention is to provide a communication system which can return an erroneous incoming message to a source facsimile apparatus by facsimile transmission.

[0011]

In order to achieve the above object, the present invention relates to a method of notifying a PBX of an incorrectly received facsimile call by using a private branch exchange (PBX). A first storage unit for storing a connection destination extension number and a network station line number corresponding to the extension, a second storage unit for storing a message message for reverse transmission, and a facsimile communication modem. And facsimile transmission of a message stored in the second storage unit to a facsimile machine of an erroneous transmission by a predetermined operation of the extension when an erroneous facsimile call is generated on an extension from the network. Features.

The present invention is characterized in that a telecommunication message transmitted by facsimile to the facsimile machine of the erroneous transmission source is added with a network line number of an extension in which the erroneous facsimile call has occurred.

According to the present invention, preferably, in a PBX capable of receiving caller ID notification information upon receiving an incoming call from a network, caller ID information, a network line number, and a connection destination extension number are stored in association with each other. A first storage unit,
A second storage unit for storing a facsimile electronic message; and a facsimile communication modem for facsimile transmitting the electronic message stored in the second storage unit. By performing a predetermined operation, the number information corresponding to the extension number of the extension terminal is extracted from the first storage unit, and at least the network office line number is added to the message message in the second storage unit. Originating and connecting to the other party based on the caller number information extracted from the first storage unit, and transmitting a message including the network line number information from the facsimile communication modem to the other party facsimile apparatus. It is characterized by.

In the present invention, the extension person who has received an erroneous facsimile call performs a predetermined operation to extract caller number information corresponding to the extension number from a memory circuit storing various number information, and make a reverse call. Can recognize the number of the other party to be done.

At the same time, the network line number corresponding to the extracted extension is taken into the message storage section of the facsimile communication modem, and the message which is erroneously received by the opposite facsimile facsimile and the telephone number which is troubled are received. Can be sent.

[0016]

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a diagram showing a configuration of an embodiment of the present invention.

Referring to FIG. 1, in an embodiment of the present invention, trunks 20 and 21 of a PBX connected to a network 110 interface communication between the extension side and the network side, and are transmitted from the network 110 when an incoming call is received. It has a function of receiving caller ID notification information.

The extension circuit 30 connects the extension telephone 40 to the PB
X is an interface housed in X.

A telegram message storage unit 50 stores in advance a telegram to be transmitted at the time of facsimile transmission, and is connected to a facsimile communication modem 60.

The facsimile communication modem 60 is used at the time of transmission to the network 110 under the control of the central processing unit 80, and performs a message transmission process after communication with the destination facsimile is established.

The number information memory circuit 90 stores destination caller number information, connection destination extension number information, and network station line number information corresponding to the connection when receiving a call from the network 110.

FIG. 2 is a diagram showing an example of the memory configuration of the number information memory circuit 90 as an example for specifically explaining the above-described embodiment.

Referring to FIG. 2, in the present embodiment, the number information memory circuit 90 stores the caller number of the called party (other party caller number) and the network station line number (dial) used for the extension number. In number) and
Under the control of the central processing unit 80, the information is rewritten every time an incoming call arrives at an extension, and the number information is transferred to the message storage unit 50 as necessary.

Next, the operation of the embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIG. In FIG. 1, P
The dial-in system used during normal business operation is adopted between the BX and the network.

When the facsimile machine 10 on the originating side receives a call to the interface trunk 20 of the PBX via the network 110, the trunk 20 receives the transmitted caller ID notification information, and then the connection extension designation number is also received. Receive.

The central processing unit 80 receives the two types of number information and transfers the trunk 20 to the extension telephone 40 (here, the extension number is “100”) via the extension circuit 30.
), The extension number information, the caller number information, and the dial-in number information are stored in the number information memory circuit 90 in association with each other.

Referring to FIG. 2, extension number "100"
Indicates that an incoming call from "06-1991-2229" is being connected, the other extension "203" is an incoming call from "0471-11-7777", and the extension 365 is free. Alternatively, it can be seen that nothing is written in the memory area of the caller number of the other party because a call is being made.

The extension person of extension number "100" responding to the incoming call from the facsimile machine 10 recognizes the facsimile erroneous call only after hearing the special sound for facsimile communication heard from the transmission and reception. I do.

Then, when the extension person performs a predetermined operation, the central processing unit 80 detects this and sends the caller ID information corresponding to the extension number “100” from the number information memory circuit 90. And dial-in number information.

Here, as the predetermined operation performed by the extension person, if the extension is a general telephone, for example, dialing a special number after hooking or dialing a special number immediately after on-hook can be selected. .

In the case of an extension telephone having a function button called a "multi-function telephone", a preset false call facsimile correspondence button is pressed. Can be selected.

Next, the central processing unit 80 instructs the trunk 21 to make a network call to the other party of the caller number to be extracted, and further connects the trunk 21 to the facsimile communication modem 60.

On the other hand, the dial-in number information extracted from the number information memory circuit 90 is stored in the message storage section 50.
The dial-in number is written to the fixed telegram message stored in advance and added to the end of the fixed telegram message or inserted in the telegram, for example.

The facsimile communication modem 60 starts communication according to a well-known facsimile communication procedure when the destination facsimile 10 responds, and stores a facsimile message stored in the message storage unit 50 (for example, a message such as " The facsimile destination phone number is incorrectly called. Please check the phone number and dial again. The wrong phone number is “03-5432-12”
30 ”is sent.), And it is automatically restored.

At this time, if the other party's facsimile 10 is busy, it is needless to say that the connection is once released and the retransmission connection is made again.

[0036]

As described above, according to the present invention,
The following effects are obtained.

The first effect of the present invention is that it is unnecessary for an extension person to know the telephone number of a destination facsimile for an erroneous facsimile call, and a facsimile message indicating an erroneous call is sent to the destination facsimile. It is possible to send.

The reason is that, in the present invention, there is provided a means for storing the caller ID information of the other party received at the time of receiving an incoming call from the network together with the extension number of the connection destination inside the PBX, thereby simplifying the extension person. This makes it possible to perform a reverse connection from the telephone number information to the destination facsimile by a simple operation.

A second effect of the present invention is that the opposite party can be automatically notified of the network line number of the erroneous call, and the other party can respond quickly. That's what it means.

The reason is that, in the present invention, means for adding a network line number used at the time of an erroneous incoming call is provided in a telegram message transmitted to the other party at the time of facsimile reverse communication.
