Sergei,
the LINE_REPLY is casting the LONG to (DWORD) but originally it is LONG like
the return value from lineGetAgentGroupList().

The error description is obtained via FormatMessage() and the
TAPIERROR_FORMATMESSAGE macro.
Please note that the MSDN sample for TAPIERROR_FORMATMESSAGE seems not to work
but htis one does:
