Remarks
If this function is called when the application has lines open or calls active, the call handles are deleted and TAPI automatically performs the equivalent of a lineClose on each open line. However, it is recommended that applications explicitly close all open lines before invoking lineShutdown. If shutdown is performed while asynchronous requests are outstanding, those requests are canceled.
