A transmission terminal is connected to a management device via a network. The transmission terminal includes an acquisition unit configured to acquire a communication state of another transmission terminal from the management device; a selection accepting unit configured to accept a selection of the another transmission terminal from a user to participate in an established session that has been already established for the another transmission terminal; a participation determination unit configured to determine that it is not possible to participate in the established session when the communication state of the another transmission terminal whose selection has been accepted indicates participation restriction; and a communication unit configured not to transmit a participation request to the management device when it is determined that the participation is not possible.
