Abstract
A system and method for performing call signalling for multimedia call setups. A user equipped with calling terminals of various types may initiate a call from any of these terminals, and the call is intercepted and handled by the system. A calling agent looks up an E-mail address for the called party, and sends a setup request E-mail to a called agent associated with the called party. The called agent determines the current terminal that the callee is using, and together with the calling agent a call medium and other parameters are established. Then a connection is made between a calling terminal and the current terminal. This provides a generic signalling system for a callee using a wireline terminal, wireless terminal, or H.323 terminal to be connected to a called terminal also being any one of these or other types.
