Track Terminals
Two types of track terminals are defined: Recording Track Terminal and Playback Track Terminal, which, respectively, belong to and are managed by File Recording Terminal and File Playback Terminal.
All track terminals expose the ITFileTrack and ITTerminal interfaces. The ITTerminal interface allows the selection of track terminals onto streams or calls.
Note
Track terminals also expose a private interface, ITMediaControl, which the MSP uses. Applications should not attempt to access this interface.
