The LINEMEDIACONTROLCALLSTATE packet defines a tuple <call states, media-control action>. An array of these tuples is passed to the SetMediaControl packet to set the media control actions triggered by the transition to the call state of the given call. When a transition to a listed call state is detected, the corresponding action on the media stream MUST be invoked.
