Abstract

A system and method for initiating and supporting network video conferences are disclosed. In accordance with the invention, one or more instant messaging enabled clients can initiate a video conference. At least a pair of client nodes communicate with each other via an instant messaging utility. An instant messaging server supports instant messages between the two client nodes. A second server, e.g., a video conferencing server, supports video conferences between video conference participants, a video conference being initiated between video conference participants in response to an instant message transmitted between the at least two client nodes.
