Abstract

PURPOSE:To improve the service performance of a private branch exchange by displaying a message designated by an extension onto a terminal equipment when a predetermined operation is applied if the terminal equipment is not connected due to its busy state or the like. CONSTITUTION:When an extension 5 makes a call while a private terminal equipment 3 is talking with a trunk line 4 and dials an extension number n2 of the private terminal equipment 3, a central controller 15 returns a busy tone. The extension 5 listening to the busy tone dials a special number nY and a message identification number ID designating a message MSG displayed on the called private terminal equipment 3. The central control unit 15 references a message registration area 162 in the main storage device 16 to extract the message MSG designated by the message identification number ID and the extension number n5 and the message MSG are displayed on the display device 35.

Description

[Detailed Description of the Invention] [Summary] In a private branch exchange that accommodates a terminal device having a character display function, when an extension that attempts to connect to the terminal device performs a predetermined operation if the connection is not successful, the By displaying the message specified by the calling extension on the terminal device, the called party can take appropriate processing.

[Industrial application field]

The present invention relates to a message display method in a private branch exchange that allows the contents of a call that cannot be answered due to an extension line to be quickly understood and appropriately handled.

As part of the diversifying RLI functions of private branch exchanges, there are services such as message waiting service, camp-on service, call waiting service, etc. that notify the called extension that a call has arrived when the called extension is busy, for example. is being put into practice.

However, none of these services allows the called party to immediately understand the contents of an incoming call, such as the caller and the level of urgency, and there has been a strong demand for improvements in these types of services.

[Conventional technology]

FIG. 4 is a diagram showing an example of a conventional private branch exchange, and FIG. 5 is a diagram showing an example of the message waiting registration procedure in FIG. 4.

The private branch exchange 1 shown in FIG. 4 is equipped with a message waiting function, and is also a dedicated terminal equipped with a message waiting lamp (ML) 33, a message waiting key (MK) 3'4, and a display device (DP) 35. The device 3 is accommodated in a dedicated extension circuit (KLC) 11 via a speech line 21 and a control line 22.

4 and 5, the dedicated terminal device 3 is connected to the central office line 4.
When the extension 5 makes a call and dials the extension number n2 assigned to the dedicated terminal device 3, the central controller
) 15 detects the call originating from extension 5 via the extension circuit (LC) 13 (step S1 in FIG. When identifying that it is the terminal device 3 and that the call is in progress (step S3), a busy tone is returned to the calling extension 5 (step S4).

When the extension 5 that hears the busy tone dials the special number nX determined for message waiting registration, the central control unit 15 receives and analyzes the dialed digits sent by the extension 5 (step S5), and sends a message. When the special number nX for waiting registration is identified (step S6), the message waiting registration area 161 provided in the main memory (MM) 16 is
The extension number n of the extension 5 is stored as the registered extension number SN, and the extension number n2 of the dedicated terminal device 3 is stored as the registered extension number DN. , transmits a message waiting display command (step S7).

In the dedicated terminal device 3, when the control circuit (CTL) 32 receives a command for message waiting display arriving from the control line 22, it lights up the message waiting lamp 33 to notify that another call has arrived during the call. Display to the person.

When the user of the dedicated terminal device 3 notices that the message waiting lamp 33 is lit, after the call with the central office line 4 ends, he puts down the handset included in the telephone circuit (place) 31 and presses the message waiting key 34. When operated, the central control device 15 detects the operation of the dedicated terminal device 3 and the message waiting key 34 via the dedicated extension circuit 11, the control line 22, and the control circuit 32 in the dedicated terminal device 3, and stores the messages in the main memory. The registered extension number 5N=n, which is stored in the message waiting registration area 161 in 16 corresponding to the registered extension number DN=n2, is extracted and sent to the dedicated terminal via the dedicated extension circuit 11 and the control line 22. Transfer to device 3.

The control circuit 32 receives an extension number n2 arriving from the control line 22.
is displayed on the display 35 to notify the user of the dedicated terminal device 3 of the calling party of the incoming call.

Note that when the user of the dedicated terminal device 3 lifts the handset and operates the message waiting key 34, the central control device 15 calls extension 5 based on the registered extension number 5N=n5 extracted from the message waiting registration area 161 and responds. Then, it is connected to the dedicated terminal device 3 via the network (NW) 14.

[Problem to be Solved by the Invention 3] As is clear from the above explanation, in a conventional private branch exchange, when the calling extension 5 of the incoming call executes the message waiting registration operation, the dedicated terminal device 3
The message waiting lamp 33 only lights up, and since the contents of the incoming call, such as the caller (extension number ns) or the degree of urgency, are unknown, the called party is unable to perform appropriate processing for the incoming call while the caller is on the line. There was a fear that this would happen.

[Means for solving problems]
