ABSTRACT:
When a teleconference among more than two places is performed using a multi-point teleconference system, each of teleconference terminal units makes a connection to a multi-point control unit by line. When the number of participants in the teleconference reduces during the teleconference so that the teleconference is performed between only two places, a conference state managing section requests the two teleconference terminal units to make a point-to-point-connection. When the point-to-point connection is acknowledge by these teleconference terminal units, the teleconference by the multi-point control unit is finished. Thereafter, the line is automatically connected between the two teleconference terminal units to perform a teleconference in the style of the point-to-point connection, so that a fee paid for use of the line is one-half compared with that in the case of the prior art.
