FIELD: radio engineering, communication.
SUBSTANCE: invention relates to communication technologies, and namely to a conference call management method, device and system. The result is achieved due to the conference call management method that includes: receiving a request of a right to speak from the first place. The said request contains the first node and the first place identifiers. The node, corresponding to the first node identifier, contains multiple places and belongs to the first conference. The first place identifier is the one, requesting the right to speak at the node, corresponding to the first node identifier. If the place is granted to the node requesting the right, then a video stream is played to the terminal of at least one node, except for the node, corresponding to the first node identifier in the first conference.
