Abstract

PURPOSE:To prevent overhear the reproduction by storing a message to a busy extension, calling it at the termination of the call and informing the presence of the message. CONSTITUTION:When a called subscriber 31 detects a busy state and a special dial requesting message recording is received, a central controller 4 executes the know procedure connecting a caller subscriber 11 to a recording area of a recording/reproduction device 5. The recording/reproduction device 5 stores an extension number of the called subscriber 31 and a message of the inputted voice from the caller subscriber 11 to a storage section 52 under the control of a control circuit 51. When the call of the called subscriber 31 is finished and hook-on state is detected and a command of the presence of a message exists in voice from the control circuit 51 in the recording/reproduction device 5, the central controller 4 sends a call signal to the called subscriber 31 to call back the message.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a message recording and reproducing system for an automatic private branch exchange having a device for recording and reproducing voice.

[Conventional technology]

Conventionally, in this type of message recording and playback system, a number is assigned to a subscriber (individual), and a recording device is called with the special number of the message service to record the message, regardless of whether the subscriber is using the service or not. Even if playback fails, the structure is such that playback will not be possible unless the subscriber consciously performs a calling operation to call up the recording device.

[Problems that the invention helps solve]

In the conventional message recording and playback method described above, when recording a message, the subscriber must memorize the assigned dial number, and even when playing back the message, the subscriber must consciously play the message. For example, if you are unable to hear the message and miss the message even though it is recorded, there will be a problem.

The purpose of the present invention is to record a message when the other party is busy,
To provide a message recording and reproducing system which solves the problems of the previous system by calling and reproducing the message when a busy subscriber ends the call.

[Means to solve the problem]

In the message recording and reproducing method according to the present invention, when a voice is recorded, the recording device 1d is connected to the calling subscriber to prepare for recording, and the recording device 1d is connected to the calling subscriber which is restored when the calling subscriber disconnects and the recording is performed. When detected, it checks whether a message has been recorded for this subscriber, and if there is a recording, when it detects this subscriber, it prepares whether or not a message has been recorded for this subscriber, and when the subscriber's response is detected, it sends out the playback voice. Has a son-in-law of 111 years.

〔Example〕

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

FIG. 1P and FIG. 2 are flowcharts showing one embodiment of the main operating procedures of the present invention, and FIG. 3 is a block diagram showing an example of the main components of a private branch exchange device that realizes FIG. 1. .

The components are listed in Figure 3.

In FIG. 3, the private branch exchange includes a main switch 2, a calling subscriber 11, a subscriber circuit 12, a called subscriber 31, a subscriber circuit 32, a recording and reproducing device 5 for recording and reproducing messages, and a recording and reproducing device 5 for recording and reproducing messages. The device 5 includes a control circuit 51h, a storage section 52, and a central control device 4 that controls the system.

Next, the procedure for recording a message will be explained with reference to FIG. 1 and FIG. 3.

When it is detected that the called subscriber 31 connected by the dialing operation of the calling subscriber 1l is busy (operation procedure S1), the central control unit 4 receives a special number dial requesting the recording of a message (operation procedure S1). Step 82). Upon reception of this special number, the central controller 4 sends the calling subscriber 11 to the recording/playback device 1e5.
The well-known procedure (operation step 1183) for connecting to the recording area of .

Since the recording/reproducing device 5 receives the message, under the control of the control circuit 51 of the recording/reproducing device 5, the extension number of the called subscriber 31 and the voice message input from the calling subscriber 11 are stored in the storage unit 5.
2 (operation procedure S4). After the input of the voice message is completed, the central control unit 4 detects the disconnection condition caused by the on/off operation of the calling subscriber 110 (operation step S5), recovers it (operation step Mis 6), and also causes the called subscriber 310 to terminate the call. wait.

Next, the message reproduction procedure will be explained with reference to FIG. 2 and FIG. 3.

When detecting an on-footer state in which the call of the called subscriber 31 has ended (operation step 811), the central control device 4 checks with the recording and reproducing device 5 whether or not a voice message is stored (operation step S12). When there is a voice instruction from the control circuit 51 in the recording and reproducing device 5 that there is a message, the middle dog control device 4 sends a calling signal to the called subscriber 31 to call it (operation procedure 813).

When a response due to the off-footer state of the called subscriber 31 is detected (operation procedure S14), the central control unit 4 performs a well-known procedure for connecting the playback area of the recording/playback device 5 to the called subscriber 31 (operation procedure S15). is executed to drive the control circuit 5l, read out the voice message stored in the storage section 52, and send it to the called party 31 (operation procedure 816).

In the above embodiment, the recording area is shown and explained as being connected by operating a special number dial when the called party is encountered while talking, but the recording area may be automatically connected when a call is detected.

〔Effect of the invention〕

As explained above, the present invention memorizes the message for a busy extension, calls it when the call ends, and alerts the extension rather than informing that there is a message. It is effective because it can prevent it from coming off.

Claims (1)

[Claims] In the message recording and playback method of an automatic private branch exchange equipped with a device for recording and reproducing voice, when the automatic private branch exchange detects that the called subscriber is busy, it connects the recording device to the calling subscriber and prepares for recording. , the system recovers by disconnecting the calling subscriber, and when it detects that a subscriber in the middle of a call has ended, it checks whether a message has been recorded for this subscriber, and if there is a message recorded, it calls the subscriber and connects it to the playback device. 1. A message recording and playback system characterized by having a central control unit that prepares for playback and sends out playback audio upon detecting a response from a subscriber.
