//
//  Arguments:	hDevice 			A handle to either a line device or a call associated 
//									with the callback. The nature of this handle (line 
//									handle or call handle) can be determined by the context 
//									provided by dwMsg. Applications must use the DWORD type 
//									for this parameter because using the HANDLE type may 
//									generate an error. 
//				dwMessage			A line or call device message. 
//				dwCallbackInstance  Callback instance data passed back to the application 
//									in the callback. This DWORD is not interpreted by TAPI. 
//				dwParam1 			A parameter for the message. 
//				dwParam2 			A parameter for the message. 
//				dwParam3 			A parameter for the message.
