A method for updating at least one data element in a conference is disclosed. The conference can include a first node having at least a first server but no endpoints; a second node coupled to the first node, the second node having at least a second server but no endpoints; a first endpoint coupled to the first server; and a second endpoint coupled to the second server. The first and second nodes can form a free tree topology. In such a conference, an exemplary method includes sending an initial update from either (a) the first server belonging to the first node, or (b) the first endpoint, to the second server belonging to the second node; receiving the initial update by the second server; and sending, by the second server, the content of the initial update as an update to at least one of a third server or the second endpoint.
