A teleconferencing system () comprises multiple teleconferencing bridges () each having an associated database (). A server () hosts a local engine () associated with each bridge, and a multi-site engine (). For a 'global' conference utilising the resources of at least one other system (), the multi-site engine () communicates over TCP/IP () with an equivalent multi-site engine of the other system to set up a link line via PSTN () between the bridges (). During the conference, the multi-site engine () automatically transmits event-driven updates to the remote system, and likewise receives such updates from the other system.
