);

hDevice

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 cause an error.

dwMsg

dwCallbackInstance

Callback instance data passed back to the application in the callback. This DWORD is not interpreted by TAPI.

dwParam1

Message-specific data.

dwParam2

Message-specific data.

dwParam3

Message-specific data.

All callbacks occur in the application context. The callback function must reside in a DLL or application module.
