The ITSubStream interface is available if an MSP is associated with the call and it implements substreams. The methods of this interface allow an application to retrieve information on a substream; to start, pause, or stop the substream; and to select or unselect terminals on a substream.
The ITSubStream interface is implemented by an MSP. Please see ITSubStream in the MSP Interface section for details on this interface.
