Abstract

PURPOSE:To recognize information such as from where a telephone call comes during the absence by displaying an incoming message stored in an incoming message memory during absence onto a character display device when a predetermined operation is implemented. CONSTITUTION:When 'call setting' information is informed to an ISDN line, a telephone number of a caller side in the 'call setting' information is stored in an incoming message buffer memory 7. When the caller gives up while no reply is received, the caller telephone number stored in the incoming message buffer memory 7 is stored in an absence incoming message memory 8. When predetermined operation for displaying an incoming message from pushbutton telephone sets 1-1-1-n onto a character display device, a central processing unit 4 displays the incoming message stored in the absence incoming message memory 8 onto a character display device of a pushbutton telephone set operated for the display via a pushbutton telephone set interface 3.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to electronic key telephone devices.

[Conventional technology]

Conventionally, this type of electronic key telephone device has a configuration in which information regarding the calling party cannot be stored when the calling party abandons the call without responding to an incoming call from an outside line.

[Problem to be solved by the invention]

The above-mentioned conventional electronic key telephone device is configured so that if the calling party abandons the call without answering an incoming call from an outside line, information about the calling party cannot be stored. If the person is absent, there is a drawback that it is not possible to know information such as where the call came from while the person was absent.

[Means to solve the problem]

The electronic button telephone device of the present invention has nine ISDN lines.
In an electronic button telephone device, the main device houses at least one button telephone with a 77-point interface and a character display, and has a central processing unit that controls the entire device, wherein the main device has a central processing unit that controls the entire device. 9 of SDN line
When "call setting" information is received from the ISDN line to the 77-point interface, an incoming message buffer memory that stores the telephone number of the calling party in the "call setting j information" and an unanswered state at the time of incoming call. an unattended message memory for storing the telephone number of the calling party stored in the incoming message buffer memory when the calling party abandons the call; a first storage control means for storing a calling party's telephone number in the incoming message buffer memory when "call setting" information is received from the ISDN line;
a second storage control means for storing the telephone number of the calling party stored in the incoming message buffer memory in the missed incoming message memory when the calling party abandons the call without answering the incoming call; , display control means for displaying an incoming message stored in the absent incoming message memory on the character display when a predetermined operation for displaying a message on the character display from each of the button telephones is performed; It has

〔Example〕

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

FIG. 1 is a block diagram showing one embodiment of the present invention.

In FIG. 1, the button telephone device of this embodiment includes a plurality of button telephones 1-1 to 1-1 each equipped with a display capable of displaying characters.
1-n (n is a natural number of 1 or more), and a main device 2 to which a plurality of key telephones 1-1- to 1-n (n is a natural number of 1 or more) are connected.

The main device 2 includes a button telephone interface 3, a central processing unit 4, a line interface 5, and a program memory 6.
The central processing unit 4 controls the main unit 2 as a whole.

Button phone interface 3 connects multiple button phones 1
-1 to 1-n (n is a natural number of 1 or more), button information or hook switch information from key telephones 1-1 to 1-n (n is a natural number of 1 or more) or a lamp from the main device 2. Exchange information, etc.

The line interface 5 accommodates 977 point interfaces of ISDN lines.

The program memory 6 stores programs for operating the central processing unit 4.

The incoming message buffer memory 7 is a memory for temporarily storing the calling number, and the unanswered incoming message memory 8 is used when the caller abandons the call without answering the incoming call.
This is a memory for storing the calling number stored in the incoming call buffer memory 7.

FIG. 2 is a flowchart showing an example of the processing of this embodiment.

Next, the operation of the button telephone device of this embodiment will be explained with reference to FIGS. 1 and 2.

When "call setup" information is notified to the ISDN line, the information is sent to the central processing unit 4 via the line interface 5. The central processing unit 4 starts the process shown in the flowchart of FIG.

First, the telephone number of the calling party in the "call setting" information sent from the ISDN line is stored in the incoming message buffer memory 7 (Sl). When the calling party abandons the call without a response (S2), the telephone number of the calling party, which is not stored in the incoming message buffer memory 7, is stored in the absent incoming message memory 8 (S3).

When a predetermined operation is performed to display an incoming message on a character display (not shown) from the button telephones 1-1 to 1-n (n is a natural number of 1 or more), the central processing unit 4 The incoming message stored in the message memory 8 is displayed via the key telephone interface 3 on the character display of the key telephone that has been operated for display.

〔Effect of the invention〕

As explained above, the present invention allows the main device to interface the S/T point of the I5DN line and
a first storage control means for storing the calling party's telephone number in the incoming message buffer memory when call setting J information is received; a second storage control means for storing in memory the telephone number of the calling party stored in the incoming message buffer memory; and a predetermined means for displaying a message from each of the key telephones on the character display of the key telephone. and a display control means for displaying the incoming message stored in the missed incoming message on the character display of the button telephone when an operation is performed.
I If you receive a call on an SDN line and the called party is absent, you can leave the caller's phone number as a message, so you can tell from where the call came from on the character display on the button telephone when you are absent. There is an effect that can be done.
