In one embodiment, the present invention is a method and apparatus for generalized third party call control in session initiation protocol networks. In one embodiment, a method for controlling a media negotiation with one or more endpoints in a network includes determining, for each endpoint, a current state of a corresponding port on a third-party controller and transitioning the corresponding port to a new state in accordance with a finite state machine that tracks the state of the media negotiation.
