A bridging system comprises a router and a number of multipoint servers. For each user requesting to join a particular conference, the router routes the call to a particular server and, if necessary, causes additional servers to be added to increase the capacity for that conference. For example, upon receipt of a user request to join a conference associated with server A, the router first interrogates server A as to current spare capacity. If server A has additional capacity, the router routes the user to server A. However, if server A can not accommodate the user, the router causes server A to invite an additional server&mdash;server B&mdash;to join the conference. After server B joins the conference, the router routes the user to server B.

A telephone apparatus enables the approximate simultaneous transmission and reception of audio interleaved with image and graphical annotation signals, in data packet form, over an analog line which connects the apparatus to a switched telephone network. The audio data packets are transmitted at a periodic rate, during a first time interval, and the image and annotation data packets are transmitted during a second time interval, following the first time interval, enabling the simultaneous output of voice, image and annotation data at the receiver site. Control data packets, as needed, are also transmitted during the second time interval for end-to-end apparatus control. One feature enables the transmission of audio data packets at a first periodic rate, when in an image transmission mode, and at a second periodic rate, faster than the first periodic rate, when not in the image transmission mode.
