Abstract
A method and apparatus for improving call setup efficiency in multimedia communication systems is disclosed. The present invention performs call setup in H.323 systems using fewer message exchanges, thereby resulting in a more efficient call setup mechanism. Moreover, no call setup functionality is sacrificed by resorting to fewer message exchanges. The method includes placing a call at a first endpoint to a remote endpoint, requesting admission from a gatekeeper for the call, returning an accept message to the first endpoint, the accept message including a token for providing information to the remote endpoint alleviating the need of the remote endpoint to request admission from a gatekeeper, routing a setup message to the remote endpoint, the setup message including the token and completing a call setup based upon information in the token.
