Remarks

The difference between pausing and stopping a stream depends on the type of transport.

If the substream pauses successfully, the application receives a CALL_MEDIA_EVENT with a value of CME_STREAM_INACTIVE and CALL_MEDIA_EVENT_CAUSE equaling CMC_LOCAL_REQUEST.

If the substream fails to pause, the event will be CME_STREAM_FAIL with cause CMC_LOCAL_REQUEST.

A call to StartSubStream restarts the substream.
