Abstract

PURPOSE:To inform the end of transmission to a text recipient without forget by setting a channel to inform the end of test transmission to the text recipient automatically when a facsimile equipment is utilized to send the text, CONSTITUTION:An extension telephone set 2 sends call request information requesting automatic dialing to an extension telephone set 3 located in the vicinity of a text recipient to inform a message relating text transmission to the text recipient after the communication between a sender facsimile equipment 4 and a receiver side facsimile equipment 1 is finished. The call request information sent by the telephone set 2 is stored in a call request storage means 9-1. When the communication between the facsimile equipments 1, 2 is finished, the end of communication is detected by a communication end detection means 9-2. An extension call means 9-3 receiving the communication end detection information outputted from the means 9-2 controls a channel switch 5 to set a channel 7 and controls the means 9-1 se as to make a call to the telephone set 3 requested by the telephone set 2. Thus, a message such as 'transmission of text is finished' is informed to the text recipient.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a private branch exchange device, and particularly to an automatic origination connection system after communication is completed.

[Conventional technology]

Conventionally, as a similar technology of this kind, there is an extension mutual camp-on connection system. The conventional camp-on method is to register in a private branch exchange to request one of the extension subscribers to make an automatic call after the end of the call, and then to make a mutual call upon receiving the call after the end of the call from the extension subscriber. This is an automatic connection service that makes it possible.

FIG. 2 is a block diagram of a conventional mutual extension camp-on system. For example, if extension 2 performs an extension mutual camp-on setting operation for extension 1 while extension 1 and extension 4 are communicating via communication path 6 of the switching device, central processing will be performed when communication between extension 1 and extension 4 ends. The device 9 detects this and sets up the communication path 8 of the private branch exchange. For example, if extension 1 and extension 2 are facsimile machines, and extension 4 sends a message to extension 1, and extension 2 is the message sender, after the message is sent, the message sender sends a message to the message receiver, for example, Even if an attempt is made to send a voice notification such as "The transmission of the message has been completed", the message cannot be sent because extension 1 is a facsimile machine.

[Problem to be solved by the invention]

In the above-described conventional mutual extension camp-on connection system, when a facsimile machine rather than a telephone is connected to extension 1, the following problem occurs.

In other words, when a facsimile machine is used to send and receive messages, the sender generally calls an extension telephone near the message recipient to notify the message recipient that the message has been sent. It is usual. In such a case, if extension 1 and extension 2 set mutual camp-on to extension 1 while extensions 1 and 4 are communicating by facsimile, after the facsimile communication between extensions 1 and 4 ends,
Extension 1 is automatically called, and extension 2 and ] are connected. However, because extension 1, which is connected to extension 2's telephone, is not a telephone but a facsimile machine, it was not possible to send a voice message from extension 2, such as "j that message transmission has been completed."

An object of the present invention is to automatically place a call from an extension located near the message sender to another pre-designated extension located near the receiving facsimile device and the message receiver after the communication between the facsimile devices is completed. It is an object of the present invention to provide an automatic connection method for a horizontal switching device, which makes it possible to notify a message such as the completion of transmission of a telegram to a message receiver when the transmission of a telegram is completed.

[Means to solve the problem]

The automatic connection system of the present invention includes: a communication end detection means for detecting the end of communication on a white line during communication; a call request storage means for storing a call request from an extension other than the white line during communication to a specific extension; and specific extension calling means for calling the specific extension stored in the call request storage means based on the communication end detection information output by the end detection means.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing a first embodiment of the present invention.

FIG. 1 shows a facsimile machine 1.4, an extension telephone 2,
3, a communication path switch 5 of the private branch exchange, a communication path 6 connecting the facsimile machines 1 and 4, a communication path 7 connecting the extension telephones 2 and 3, and a call request storage means 9- for which the extension telephone 2 requests. 1. Facsimile machine 1.4 Communication end detection means 9-2 for detecting the end of communication between each other, extension telephone 3 stored in call request storage means 9-1 based on communication end detection information
The call path switch 5 of the private branch exchange equipment
The central processing unit 9 includes an extension calling means 9-3 for controlling the communication path 7 and forming the communication path 7, and a storage device 10 containing control information such as call processing of the private branch exchange.

After the communication between the sending facsimile device 4 and the receiving facsimile device 1 is completed, the extension telephone 2 automatically sends a message to the extension telephone 3 located near the message recipient in order to notify the message recipient of messages related to message transmission. Sends call request information requesting a call.

The call request information sent by the extension telephone 2 is stored in the call request storage means 9-1.

When the communication between the facsimile machines 1 and 4 is completed, the communication end detection means 9-2 detects the end of the communication. The extension calling means 9-3, which receives the communication end detection information outputted by the communication end detecting means 9-2, controls the call path switch 5 to set the call path 7 and also stores the call request storage means 9-1. The system then controls the extension telephone 2 to place a call to an extension telephone 3 located near the requested message recipient.

In this way, a communication path 7 is formed between the extension telephones 2 and 3, and it is possible to notify the recipient of the message, for example, that the transmission of the message has been completed.

In the above explanation, the case of an extension line accommodated in one private branch exchange device was explained, but it goes without saying that the same operation can be performed in a system configured with a plurality of private branch exchange devices connected via a dedicated line. do not have.

〔Effect of the invention〕

As explained above, according to the present invention, when a message is sent using a facsimile device, a communication path for notifying the message recipient that the message transmission has been completed is automatically set. Therefore, the recipient of the message can be notified of the completion of transmission without forgetting the completion of the transmission, and this has the effect that the recipient of the message can go to the facsimile device that received the message and reliably obtain the message.

Furthermore, instead of the message sender directly notifying the message recipient by voice, it is also possible to automatically notify the message recipient by recording a notification message in a voicemail in advance. In this case, the burden on the sender of the message is further reduced because the message does not need to be sent by simply registering automatic connection via voice mail.
