LINEMEDIACONTROLCALLSTATE

The LINEMEDIACONTROLCALLSTATE structure describes a media action to be executed when detecting transitions into one or more call states. The lineSetMediaControl and TSPI_lineSetMediaControl functions use this structure.

typedef struct linemediacontrolcallstate_tag {
  DWORD  dwCallStates;
  DWORD  dwMediaControl;
} LINEMEDIACONTROLCALLSTATE, FAR *LPLINEMEDIACONTROLCALLSTATE; 

Members

dwCallStates

Specifies one or more call states. This member uses one of the LINECALLSTATE_ Constants.

dwMediaControl

The media control action. This member uses one of the LINEMEDIACONTROL_ Constants.

Remarks

This structure may not be extended.

The LINEMEDIACONTROLCALLSTATE structure defines a triple <call state(s), media-control action>. An array of these triples is passed to the lineSetMediaControl function 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 is invoked.
