wine users - Sep 2010 - Microsoft TAPI 2.1

I have an application which runs fine under the latest version of WINE. 
However, when it tries to initialize the TAPI services, I get the following
error.

Cannot find import; DLL may be missing, corrupt, or wrong version
File "TAPI32.DLL", function "lineGetMessage" (error 0)

I have verified the DLL in fact does exist.  I'm wondering if the version of
TAPI compiled in WINE is not Microsoft's v2.1

If it is not, does anyone know where to download and how (if it is possible) to
install v2.1 in WINE?
