Defines the level of tracing for the H.324M Middleware. Applications can invoke h324SetTrace any time before or after invoking h324Initialize.

DWORD h324SetTrace ( unsigned int LogToConsoleMask, unsigned int LogToFileMask)

The following bits can be turned on or off for both LogToConsoleMask and LogToFileMask:
