I have it. By setting the automatic / manual switch A4, the line connection of the conference participant A11 /
At the time of disconnection, automatic line connection / disconnection of the line connected to the line connection terminal A2 of the multipoint teleconference terminal A1 becomes possible.

FIG. 3 shows a procedure for implementing the multipoint conference service of the present invention. The procedure will be described with reference to the detailed configuration diagram of FIG.

First, when using the multipoint telephone conference service of the present invention, the representative A13 participating in the conference dials the reserved telephone number A12, the date and time of the event, the number of participants, the telephone numbers of all the participants, and the conference. Send information such as time to the operator at the center to apply (Step B
1).

Upon receiving the application, the operator confirms the reservation status by checking from the reservation status list of the reservation management terminal A14 whether the line is free at the date and time of the application (step B2).

As a result of the investigation, the designated telephone number is used to notify whether or not the reservation can be made at the date and time when the application is made, and if the reservation is possible, the designated telephone number A9 to be called when attending the conference is also notified (step B3). ).

Upon confirming the designated telephone number, the conference attendant representative A13 informs all the attendees of the designated telephone number A9 notified by the center when the reservation is possible at the requested date and time (step B4). The conference attendant representative A13 informs the attendee telephone numbers A10 of all the participants in the conference to the operator on the center side (step B5).

The operator confirms the participant telephone numbers A10 of all the participants of the conference notified in step B5 (step B6).

The conference participant A11 who has applied for the reservation calls the designated telephone number A9 notified by the operator at the time of application at the conference start time (step B).
7).

The operator responds to each call from the conference participant A11 on the telephone number confirmation terminal A on the center side.
In step 5, it is confirmed whether or not it is the participant telephone numbers A10 of all the conference participants A11 notified at the time of application (step B8).

The operator pushes the incoming call switch A3 from the line where the participant telephone number A10 can be confirmed to connect the line. At this point, the automatic / manual switch A4 is set to "manual setting" (step B9).

When the mediation of the line connection of all the conference participants A11 is completed, the confidentiality switch A is set so that the operator performing the mediation operation of the line connection cannot hear the contents of the conference.
The mediating voice interface A6 is disconnected by 7. At this time, the automatic / manual switch A4 of the existing multipoint telephone conference terminal A1 is set to "automatic setting". With the above setting, when the conference participant A11 disconnects the participant telephone number A10 on each side at the end of the conference, each designated telephone number A9 connected to the existing multipoint telephone conference terminal A1 on the center side is disconnected. The line can be disconnected automatically (step B10).

The conference participant A11 hears the completion report of all line connection from the operator and starts the conference (step B1).
1).

At the end of the conference, the conference participant A11 disconnects the participant telephone number A10 of its own line, regardless of whether the conference end time reserved at the time of application is reached. Since the existing multipoint telephone conference terminal A1 on the center side is "automatically set", the line of each designated telephone number A9 is disconnected when each conference participant A11 disconnects the line (step B12).

The operator confirms the incoming call switch A3 of the multipoint telephone conference terminal A1 when the conference end time reserved at the time of application comes. If the incoming call switch A3 is off, the conference is finished and the line is disconnected. If the incoming call switch A3 is still on, the operator closes the confidentiality switch A7 and connects the intermediary voice interface A6 to notify the conference participant A11 that the end time has come (step B13).

[0024]

The effect of the present invention is to use a multipoint telephone conference terminal capable of connecting a general public telephone line network between N points and making simultaneous calls, and to use a device capable of confirming the telephone number of the other party. In addition, by providing a switch that cuts off the voice interface that mediates the line connection of all the conference participants in the multipoint conference call terminal, it is possible to use a general public telephone line network without owning a telephone line network. By using it, it is possible to construct a system of conference call service.
