JPS61205060A - Automatic substitute sound record acceptance system in extension busy mode for automatic private branch exchange equipment - Google Patents

Abstract

PURPOSE:To omit troublesome operations for a called subscriber and also to transmit messages accurately by performing automatic substitute sound recording in an extension busy mode. CONSTITUTION:An extension subscriber EXB calls another extension subscriber EXA while the EXA is talking with a trunk line via a route of a channel switch SW(1). In such a case, a central controller CC reads out the contents of a busy extension memory circuit 2 after the extension number of the EXA is dialed and discriminates a busy mode of the EXA. Then the controller CC retrieves the inside of a register/memory circuit 1 in an extension busy mode to discriminate whether the EXA is registered or not. If the EXA is not registered, the busy tone is given to the EXB. While the automatic substitute sound record signal, the calling extension number (extension number of EXB) and the calling extension number (extension number of EXA) are sent to a voice memory 4 from the controller CC when the EXA is registered. Then the connection is closed between the EXB and the memory 4 by a route of a channel switch SW(2).

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an automatic proxy recording acceptance system when an extension line is busy in an automatic private branch exchange.

(Prior art) When calling the other party when the extension is busy, the caller has to wait a while and then call again. Also, even if an extension representative group is set, other people may answer the call. Become,
It was necessary to convey a message or call back again.

(Object of the Invention) An object of the present invention is to automatically connect to a substitute recording device when an extension is busy and record a message from the other party, and to automatically connect the extension to the recording device after the extension has finished a call and record the message contents. To provide an automatic proxy recording acceptance system when an extension line is busy, which solves the above-mentioned drawbacks by transmitting the message to the extension person, eliminates the trouble of the other party, and can accurately convey the message.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the automatic on-premises call machine according to the present invention has an automatic proxy recording reception method when an extension line is busy. A voice storage device for storing incoming messages, a busy extension storage circuit for storing when an extension subscriber is busy, and an automatic proxy recording service for each extension subscriber when the extension is busy can be registered. It is equipped with an automatic proxy recording service registration storage circuit and a recording extension storage circuit for storing a message to a predetermined extension subscriber to the effect that a message is stored in the voice storage device, If the called party is busy, the automatic proxy recording service registration memory circuit is searched, and if the called party is receiving the automatic proxy recording service, the voice storage device is stored in the voice storage circuit. When the caller is connected and the calling party's message is stored in the voice storage device, that fact is stored in the recording extension storage circuit, and after the called party finishes speaking and dies, the recording extension storage circuit is retrieved. As a result, when it is detected that a message is stored in the voice storage device, the called party is called, the device is connected to the voice storage device, and the message is sent.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a relay system diagram showing an embodiment of an automatic private branch exchange apparatus to which an automatic proxy recording acceptance system when an extension line is busy according to the present invention is applied.

In Fig. 1, when the extension subscriber EXA and the central office line are connected to the route shown by ■ of the communication path switch SW, the extension subscriber EXA
All assume that B calls extension subscriber EXA. Second
The figure shows the flow of operations after t when extension subscriber EXB makes a call to extension subscriber EXA. Extension subscriber EX
When A's extension number is dialed (Fig. 2 a), the central control unit 00 reads the contents of the busy extension memory circuit 2 and identifies that extension subscriber] 13XA is busy (Fig. 2 b).
. Next, the central control unit OO searches the automatic proxy recording service registration storage circuit 1 during an extension call and identifies whether the extension subscriber EXA is registered (FIG. 2C).

If extension subscriber EXA is not registered, extension subscriber E
Make the XB listen to the busy tone (Figure 2 d).

If extension subscriber EXA is registered, the central control unit Co sends an automatic proxy recording signal, calling extension number (EXB extension number) and called extension number (EXA extension number) to the voice storage device 4. The connection between the subscriber BXB and the voice storage device 4 is closed by the path of the communication path switch SW■ (second
Figure e). Transfer from voice storage device 4 to extension subscriber BXB-
If there is a problem with changing the entrance and the left while the staff is on duty, tell the staff that the recording will be made, and after a certain period of time, tell them to start recording (Fig. 2). If extension subscriber BXB does not need to convey a message, the message will not be recorded in the voice storage device 4 by lowering the handset within a certain period of time (Fig. 2g, h).

If the extension subscriber 'BXB wants to send a message in its entirety, he hears that the recording has started, and after he dies, he sends the message, and the voice storage device 4 records the message (Fig. 2g, i).

When the extension subscriber EXB hangs up the handset after transmitting the request (FIG. 2j), the line circuit LOB detects recovery. When the central control unit CO identifies that the extension subscriber EXB has been restored, it opens the switch (Fig. 2k) and then switches the recording extension storage circuit 3.
The extension number of extension subscriber FJXB is temporarily stored in the address of extension subscriber EXA (FIG. 2°C).

Next, when the extension subscriber EXA puts down the handset (FIG. 2m), the line circuit EXA detects recovery.

When the central control unit Co identifies that the extension subscriber EXA has been restored, it opens the path marked ■ of the switch SW (Fig. 2 m).
. Next, the central control unit OC searches the recorded voice storage device 3,
It is determined whether a message is registered with extension subscriber EXA (FIG. 2, 0). If a message is registered, a ring tone is sent to extension subscriber EXA (Fig. 2 q)
). When the extension subscriber EXA lifts the handset (Fig. 2 r), the line circuit LOA detects this, and the central controller CC stops the ringer and sends a substitute recording/playback signal to the voice storage device and the calling extension number (EXB). extension number] and the called extension number (EX
A's extension number) is sent, and the extension subscriber EXA and the voice storage device 4 are connected through the path ■ of the switch SW (
Figure 2 S) The voice storage device 4 notifies extension subscriber EXA that there is a message from extension subscriber EXB and reproduces the message contents (Figure 2 t).

When the extension subscriber EXA lowers the handset (U in Figure 2), the line circuit LOA detects the restoration, and when the central control unit OC identifies the restoration, the channel switch SW (■) is opened and the recording extension memory is activated. The extension subscriber EXB number temporarily stored in the address of the extension subscriber EXA of the circuit is deleted.

Next, the central control unit 00 searches the recording extension storage circuit 3 again to determine whether or not another message is registered for the extension subscriber EXA.

If there are any other messages, call extension subscriber EXA again as described above and convey the contents of the message.

(Effects of the Invention) As explained above, the present invention has the advantage that by automatically recording on behalf of the caller when an extension call is in progress, it eliminates the complexity of operations for the caller, and also allows the message to be conveyed accurately. There is.
