Bug #: 31717
           Summary: aplication crashes when attempting to interact with
                    TAPI32 - unimplemented? Tapi32.dll.lineInitializeExW
           Product: Wine
           Version: 1.4
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: tapi32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

application Cortex, after installation went OK, and it started fine
it crashed when trying to work with some telephony subsystem with the following
error:

fixme:winmm:MXD_SetControlDetails What should the sw-side mixer controls map
to?
wine: Call from 0x7bc49f20 to unimplemented function
Tapi32.dll.lineInitializeExW, aborting

I would love to get it working under Linux - but I have very little experience
with wine.
I have installed wine-dbg but I guess it is a little use of this function call
is simply unimplemented ?

How do I get more info on what exactly is wrong ?
Maybe initialization of  lineInitializeExW is trivial?
