It is.

(Example) The present invention will be explained in more detail below with reference to one drawing.

FIG. 1 is a diagram showing an embodiment of the conference telephone system according to the present invention, and is a relay system diagram in the storage program control system of an automatic telephone exchange.

Meeting convener A decides on the people to be convened, forms a group,
The case of registering this will be explained. When the conference convener A dials the subscriber numbers of the conveners B, C, and D of the group "'50" by a predetermined operation, the group information is sent to the central control unit [CC] via the number receiving register R8Ti. sent to. Main storage device M in central controller CC
The convened person number of group 150n is registered in the O-group M group memory in the main memory M as shown in FIG.

Using a similar method, convener A can preset conveners E, F in group "51" and convenees E, F, G, Hi in group "52".

Next, a case where subscriber A calls a meeting will be explained. E. as the necessary convened persons for the meeting.

If subscriber F wants to participate, subscriber A dials only the group number "51" after the special number without dialing JF's subscriber number sequentially. The special number and group number "51" are stored in the subscriber number receiving devices R and ST.

It is sent to the central controller CC. The central controller CC analyzes the special number and, if it determines that it is a conference call, stores the main memory M
