Abstract
A system and method for presence-based video and multimedia calling by which a workstation is dynamically associated with a user based on user log-in information so that video and multimedia calls are routed to at least one workstation at which that user is logged in. This allows a caller to place a video or multimedia call to a recipient without knowing the network address of the workstation at which the user is logged-in or the physical location of the recipient. The invention provides for detecting whether a participant is logged into the network and notifying the caller accordingly. The invention further provides for the routing of AV and data signals among workstations dispersed over multiple LANs, on different networks, or at different locations. Mulitple types of services and signal format standards may be supported within the same call. Network and workstation capabilities may be included as calls follow a user to any workstation in the system.
