Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention registers a message from an extension of the calling side when the extension of the called side is busy or does not respond, and thereafter, this message is called by an instruction from the extension of the called side. The present invention relates to a private branch exchange having a function of sending to a side extension.

[0002]

2. Description of the Related Art Recently, various service functions have been enhanced in a private branch exchange (PBX). One of the service functions is to register a message from the calling extension when the called extension is busy or does not respond, and then send this message to the called extension by an instruction from the called extension. There is something to send. However, the calling user can send a necessary message to the called user without any operation after the called user is busy or absent. Can be performed reliably and easily.

However, in the conventional service function of this type, once a message is registered from the extension of the calling side, the registered message is transmitted until an instruction is given from the extension of the called side and the message is sent to the extension of the called side. Is not erased,
A message that is no longer necessary for the calling user is sent to the called user, causing various inconveniences. For example, the calling user registered a message saying "please call me" because the called user was absent, etc., and then left or registered such a message for some reason. Suppose you forget and went home. Then, even if the called user subsequently reads out the above-mentioned message and calls the calling user, the user becomes absent.

[0004]

When the extension of the called side provided by the conventional private branch exchange is busy or there is no response, a message from the extension of the calling side is registered, and this message is then sent to the extension of the called side. In the service function that sends to the extension of the called side by the instruction from, once the message is registered from the extension of the calling side, the message is registered until the extension from the called side sends the message to the extension of the called side. Messages are not erased, so messages that are no longer needed by the calling user are sent to the called user,
It causes various inconveniences.

The present invention has been made to solve such a problem. When the extension of the called side is busy or there is no response, a message from the extension of the calling side is registered and the called side is registered. Providing a private branch exchange in which a message that is unnecessary for the calling user is not sent to the called user when it has a function to send the message to the called extension by an instruction from the extension The purpose is to do.

[0006]

According to the present invention for achieving the above object, a message from a calling side extension is registered in advance when the called side extension is busy or there is no response from the called side extension. In a private branch exchange having a function of sending the message to the extension of the called side in accordance with the instruction, the input means for inputting the valid time for registering the message from the extension of the calling side, and the input means. Storage means for storing the valid time associated with the message corresponding to the valid time, and erasing means for erasing the message corresponding to the valid time when the valid time stored by the storage means has elapsed. It is a thing.

[0007]

According to the present invention, when a valid time for registering a message, for example, a calling user sets a time during which the telephone can be received by the telephone, the message is registered only within the valid time and then deleted. Therefore, a message that is unnecessary for the calling user is not sent to the called user.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a diagram showing the configuration of a private branch exchange according to an embodiment of the present invention.

As shown in FIG. 1, extension telephones 1a, 1n, which are, for example, electronic key telephones, are connected to a speech path network (SW) 3 via line circuits (LC) 2a, 2n of an exchange, respectively. ing. In addition, a trunk circuit (TRK) 4 is provided in this communication path network 3.
A plurality of station lines are respectively connected via a and 4m.

A central control unit (CC) 6, a storage unit (MEM) 7 and a message storage unit are connected to the line circuits 2a to 2n, the communication network 3, and the trunk circuits 4a to 4m via a control data bus 5. (Message M
EM) 8 is connected. The central controller 6 controls the line circuits 2a to 2n and the trunk circuit 4 in accordance with the operation program and various control information stored in the storage device 7.
Information for call control and the like are transmitted and received between a and 4 m to control the formation of a call path between the extensions and between the extension and the office line by the call path network 3.

Further, when the extension of the called side is busy or there is no response, the message from the extension of the calling side is registered only during the valid time, and during the subsequent valid time, this message is instructed from the extension of the called side. In order to realize the function of sending to the extension of the called side by the message storage device 8, as shown in FIG. 2, the extension number of the called side (DN1), the message, the extension number of the calling side (DN2) and the valid time are stored. Are stored in association with.
In addition, the extension telephones 1a to 1n perform registration and message display of these, so as shown in FIG. The display unit 12 is provided with a soft key 13 for displaying, a function key 14 for notifying that a message is registered by blinking red, and a soft key 15 for displaying a registration message or the like on the LCD display unit 12 when pressed.

Next, the operation at the time of input for realizing the service function of the present invention will be described based on the flowchart shown in FIG.

When a dial number is input from the extension telephones 1a to 1n (S401), it is first determined whether the extension call is made or the outside call is made based on the inputted dial number (S402).
).

If the call is an outside call, it has nothing to do with the service function of the present invention, and therefore the normal outside call processing is performed (S403).

If the call is an extension call, the extension on the called side is discriminated and specified based on the input dial number (S404).
), It is determined whether the called extension is busy (S405).

If not busy, the timer is started (S406), and a response is given from the extension of the called side within a predetermined time (S40).
If there is 7,408), normal call processing is performed (S409).

On the other hand, when there is no response from the extension on the called side within a predetermined time (the extension on the called side is considered to be absent) (S407, 408)
Alternatively, when the extension of the called side is busy (S405), a timer is started (S410), and if a message is input from the extension of the calling side within a predetermined time (S411,412), the extension number of the calling side ( It waits for the input of DN2) (S413) and the input of the valid time (S414). When a message, a calling side extension number (DN2) and a valid time are input from the calling side extension, these are registered in the message storage device 8 (S415) and the line is disconnected (S416).

If no message is input from the extension on the calling side within a predetermined time (S411, 412), it is considered that there is no intention to register the message and the line is disconnected (S417).
).

Next, an example of operation on the calling extension telephone will be described.

For example, the user of the extension telephone with the extension number 4311 (extension of the calling side) has made an extension call to the extension telephone of the extension number 4321 (the extension of the called side), but is "busy". Register the message of the valid time 13:00
The case will be described.

First, a message is registered. This is because every time the soft key 13 is pressed, a message to be sequentially registered is displayed on the LCD display unit 12. Therefore, when the “call me” message is displayed on the LCD display unit 12, the soft key 13 is pressed. Stop by pressing "1" of the dial key 11.

Next, the extension number (DN2) of the calling side is input. This is done by pressing the dial key 11 "4311".

Next, the effective time is input. This is done by pressing the dial key 11 "1300".

Next, the operation after registration for realizing the service function of the present invention will be described with reference to the flowchart shown in FIG.

When the registered extension of the called side is registered in the message storage device 8 as described above (S501), it is confirmed whether the registered extension of the called side is busy (S502). A command signal is sent to make 14 blink red (S503).

After that, when the soft key 15 is pressed on the telephone of the extension of the called side and the command signal for sending the registration message or the like is received from the extension of the called side (S504), the registration message or the like is sent to the extension of the called side. This is sent (S505), and these registration messages and the like are displayed on the LCD display unit 1 of the extension telephone of the called side.
Display on 2.

Then, the registration message or the like is deleted from the message storage device 8 (S506).

If the current time exceeds the registered valid time (S507), the registration message or the like corresponding to the valid time is deleted (S506).

As described above, in the private branch exchange of this embodiment, the message from the extension on the calling side is registered only during the valid time, and after the valid time elapses, the registration is deleted so that the message is not sent to the extension on the called side. Therefore, a message that is no longer necessary for the calling user is not sent to the called user.

The present invention is not limited to the above embodiment.

For example, the effective time may include not only time but also date.

The message registration operation or the like may be performed by a special dial number operation.

Further, the message may be inputted by voice.

[0035]

As described above, according to the private branch exchange of the present invention, when the extension of the called side is busy or there is no response, a message from the extension of the calling side is registered and the extension of the called side is registered. If you have a function to send the message to the extension of the called side by the instruction of, if you set the valid time for registering the message, the message will be registered only during the valid time and will be deleted after that. Messages that are no longer needed by the user are never sent to the called user.
