Abstract

PURPOSE:To deliver a reason of calling or a name of a conference or the like to a called conference participant by displaying a different display message from each occasion on a display device of an extension telephone set for a conference sponsor and conference participants. CONSTITUTION:At first, a conference sponsor dials a preset conference special number from an extension telephone set 1 and dials an extension number of an extension telephone set 2 of a conference participant and a display message number 20 inserted between two codes (*) consecutively. A central controller 13 receiving the dial signal from the extension telephone set 1 connects the extension telephone set 1 to a conference trunk 12 via a main switch 11 to call the extension telephone set 2 and to read a conference name A being a message corresponding to the dialed display message number 20 among messages stored in a storage circuit 14 and the message is displayed respectively on a display device of the extension telephone sets 1, 2. After the reply of the extension telephone set 2, the central controller 13 connects the extension telephone set 2 to the conference trunk 12 through the main switch 17.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic automatic private branch exchange, and more particularly to a conference call system.

[Conventional technology]

Conventionally, in this type of conference telephone calling method, when a conference call is held using a conference telephone, the person convening the conference calls each conference participant from an extension telephone and connects to the conference trunk of the switching equipment. A fixed message was displayed on the display of the extension telephones of the convenor and conference participants.

[Problem to be solved by the invention]

In the conventional conference telephone calling method described above, when the conference convenor calls each conference participant, a fixed message is displayed on the display of the extension telephone of the called conference participant, so the message is different each time. It is not possible to convey the reason for being called, the name of the meeting, etc. to the called conference participants.

[Means to solve the problem]

The conference telephone calling system of the present invention accommodates an extension telephone with a display, and when a conference convenor calls each of the conference participants, a message is sent to the display on the extension telephone of the conference participant. In an electronic automatic private branch exchange having a display function, a message is registered in advance in correspondence with a display message number, and the conference convenor sends the extension number of the conference participant and the display message number. When a participant's extension telephone is called, a message corresponding to the displayed message number is displayed on the display of the extension telephone of the conference convenor and the conference participant.

〔Example〕

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

Referring to FIG. 1 showing the configuration of an embodiment of the present invention, 1
is the extension telephone of the conference convener, 2, 34.5 is the extension telephone of the conference participant, 6, 7, 8゜9.10 is the line circuit of extension telephone 1, 2, 3, 45, respectively, 11 is the main switch, 12 is a conference trunk, 13 is a central control unit, and 14 is a storage circuit. The main switch 11 includes line circuits 6, 78 .
via 9.10 accommodates extension telephones 1.2.3°4.5, also accommodates conference trunk 12, central control unit 13
Executes mutual exchange connection under the control of The conference trunk 12 is connected via a plurality of main switches 11 among the extension telephones 1 2.3 and 4.5, and realizes a conference through mutual calls. The central control unit 13 controls the main functions of the switching device, mainly controls the main switch 11, and performs mutual exchange connections between the lines and devices accommodated in the main switch 11.

The storage circuit 14 is capable of storing a plurality of messages in correspondence with display message numbers, and here, it is assumed that conference base A is previously stored in correspondence with display message number 20, and agenda B is stored in correspondence with display message number 21.

First, the conference convenor dials a preset conference special number from the extension telephone 1, and then consecutively dials the extension number of the extension telephone 2 of the conference participant and the displayed message number 20 with the symbol * in between.

Central control unit 1 receives the dial from extension telephone 1
3 connects extension telephone 1 to conference trunk 12 on main switch 1.
1, calls the extension telephone 2, reads out the conference card A, which is the message corresponding to the dialed display message number 20, from among the messages stored in the memory circuit 14, and calls the extension telephone 1.2. Display each on the display. After the extension telephone 2 answers, the central controller 13 connects the extension telephone 2 to the conference trunk 12 via the main switch 11 . If the conference convenor performs a call termination operation from the extension telephone 1 before the extension telephone 2 answers, the call to the extension telephone 2 is stopped.

Next, the conference convener performs the above-mentioned dialing operation from the extension telephone 1 to the extension telephones 3, 4.5 of other conference participants. The central control unit 13 in each case connects the extension telephone 3.
4.5, reads and compares the message corresponding to the dialed display message number from among the messages stored in the memory circuit 14, and calls extension telephones 1, 3,
Display on the 4°5 display. Furthermore, an extension telephone 3.
4.5 answers, the central control unit 13 connects the extension telephone 3.4.
．． 5 is connected to the conference trunk 12 via the main switch 11. Therefore, a conference can be held between the conference convenor's extension telephone 1 and the conference participants' extension telephones 2, 34.5 via the conference trunk 12.

In the above explanation, since the displayed message number can be dialed differently each time, even participants in the same conference call can receive different displayed messages (in this example,
Meeting base A and agenda item B) can be displayed. Also,
If you do not dial the display message number, nothing is displayed but a fixed message is displayed. Furthermore, although it has been explained that the code * is dialed as a boundary between the continuously dialed extension number and the displayed message number, the present invention is not limited to this as long as the code is distinguishable. Therefore, a numeric code may be used as long as the number of digits and the first digit number are limited.

〔Effect of the invention〕

As explained above, according to the present invention, a plurality of messages are registered in advance corresponding to the display message numbers, and the conference convenor sends the extension numbers and display message numbers of the conference participants. When calling an extension phone, a message can be displayed each time on the display of the extension phone of the conference convenor and conference participant, and the reason for the call, the name of the conference, etc. This can be communicated to the participants.
