Abstract

PURPOSE: To provide a private branch exchange with which a message can be recorded from a terminal on the side to be held when holding speaking. CONSTITUTION: This device is provided with plural terminals A and B, holding melody unit 7 for sending a holding melody to the terminals A and B, message recording unit 8 for recording, reproducing and sending voices from the terminals A and B, and connecting means 5 for connecting these terminals A and B, holding melody unit 7 and message recording unit 8. During the connection control between the terminals A and B and the speaking between the terminals A and B, connection control is performed so that one terminal can be connected to the holding melody unit 7 in response to a holding operation from the other terminal B, and the voice of one terminal A is recorded by connecting one terminal A to the message recording unit 8 corresponding to a special number input from one terminal A during this holding. Next, a control means 6 is provided to reproduce and send out the voice by connecting the other terminal B to the message recording unit 8 after the speaking of one terminal A is disconnected.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a private branch exchange for controlling connection of a plurality of terminals, and more particularly to a private branch exchange having a message recording function.

[0002]

2. Description of the Related Art Conventionally, the message recording function provided in this type of private branch exchange is used for answering machine recording, call recording, etc. Normally, when a recording instruction is issued from a telephone connected to the private branch exchange, the private branch exchange is equipped with the message. I was able to record a message in the message recording unit.

[0003]

However, in the conventional private branch exchange, there is no message recording function on hold, and when a hold operation is performed on the telephone, the other party's telephone can unilaterally hang up. Can not. That is,
When the holding time of the telephone becomes long, it is impossible to hang up the telephone by telling the intention from the other party's telephone, and in many cases, it is a waste of time to wait until the holding is released for a long time.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a private branch exchange capable of recording a message from a terminal on the held side when a call is on hold.

[0005]

To achieve the above object, the present invention comprises a plurality of terminals, and a holding melody unit which is connected to the terminals and sends a holding melody to the terminals.
The terminal has a message recording unit which is connected to the terminal to record a voice from the terminal and reproduces and transmits the recorded voice, and a connection unit which connects the terminal, the hold melody unit and the message recording unit. Connection control for connecting the other terminal to the holding melody unit in response to a holding operation from one terminal during a call between the terminals and the other terminal while holding the one terminal. In response to the special number input from the terminal, the other terminal is connected to the message recording unit to record the voice from the other terminal, and after the call disconnection of the other terminal, to the hold re-response of the one terminal. Further, a control means for connecting the one terminal to the message recording unit and reproducing and transmitting the voice is provided.

[0006]

With this configuration, when the other terminal wants to hang up while the other terminal is on hold, the other terminal can enter a special number and leave a message in the message recording unit. Since the one terminal is connected to the message recording unit at the same time as the hold re-answer, the message from the other terminal can be heard.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a private branch exchange according to the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a private branch exchange apparatus according to the present invention. In FIG. 1, the other terminal, a telephone A, is connected via an extension circuit 3, and one terminal, a telephone B, is an extension. It is connected to the exchange circuit 5 as a connecting means via the circuit 4.

The exchange circuit 5 is further connected to a holding melody unit 7 for sending a holding melody and a message recording unit 8 for controlling a message recording operation during holding.

The exchange circuit 5, the extension circuits 3 and 4, the hold melody unit 7 and the message recording unit 8 are controlled by the CPU unit 6 which is a control means, and CP
On the memory 6a of the U unit 6, there is a state management table for monitoring the states (calling, receiving, holding, recording) at the time of line connection.

Next, the operation of the above embodiment will be described with reference to FIGS. 2 is a flow chart showing the operation procedure of the recording function in the private branch exchange according to the present invention, and FIG. 3 is a diagram showing the change of the state management table accompanying the operation of the recording function in the private branch exchange. , The telephone A goes off-hook (step S1), and when the telephone B answers the call from the telephone A (step S2), the telephone A and the telephone B switch the extension circuits 3 and 4 to the switching circuit 5 respectively.
A call is in progress via (step S3). In this state, the state management table of the CPU unit 6 becomes the table state 1 shown in FIG.

When the telephone set B is put on hold (step S4),
CPU unit 6 is telephone A and hold melody unit 7
And the hold melody is sent to the telephone A (step S5).

When the telephone A wants to hang up while the telephone A is on hold, the special number preset in the telephone A is pressed (step S6), the CPU unit 6 recognizes the special number, and the destination of the telephone A is connected. Is switched from the hold melody unit 7 to the message recording unit 8.
In this state, the state management table of the CPU unit 6 becomes the table state 2 shown in FIG.

Since the message recording unit 8 prompts the telephone A to record a message, the telephone A records a message from the handset (step S7). When the recording of the message is completed, the telephone set A is hooked on (step S8). In this state, the state management table of the CPU unit 6 becomes the table state 3 shown in FIG.

Simultaneously with the hold re-response of the telephone B (step S9), the CPU unit 6 connects the message recording unit 8 and the telephone B, and sends the message recorded by the telephone A (step S10). In this state, the state management table of the CPU unit 6 becomes the table state 4 shown in FIG.

After confirming the message from the telephone set A, the telephone set B goes on hook (step S11).

As described above, according to the private branch exchange having the above structure, even if the telephone set B is put on hold during a call, the telephone set A can leave the message to the telephone set B and hang up.

In the above embodiment, telephones A and B are used.
Is an extension telephone connected to the exchange circuit 5 via the extension circuits 3 and 4, but it is similarly possible when the exchange circuit 5 is connected to the public network and the telephone set A is an outside telephone.

[0019]

As described above, according to the present invention, when the other terminal wants to hang up while the other terminal is on hold, the other terminal inputs a special number and sends a message to the message recording unit. You can leave. Since the one terminal is connected to the message recording unit at the same time as the hold re-answer, the message from the other terminal can be heard.

That is, according to the present invention, even when the holding of the one terminal takes a long time, or when the other terminal has to hang up due to an urgent business while the one terminal is held. , A message can be recorded and the call can be hung up, and the other terminal can confirm the requirements of the other party after holding and answering again, so there is no annoyance like when the call is unilaterally hung up. Since the communication leakage is reduced, the communication can be smoothly performed.
