Nick,
basically I can't see that you are doing anything wrong, but
regarding TAPI and .NET see KB article
"841712 - Telephony Application Programming Interface
(TAPI) functionality is not supported from managed code".
http://support.microsoft.com/?id=841712
That being said you should start with the basics for further
examination. Use TapiBrowser 3 (if you're more familiar
with this object model) and Windows Sound Recorder
(soundrec.exe) and try to reproduce the issue. For using
Windows sound recorder with your modem you need to
set the system default audio devices to the modem's
audio devices.
Best regards,
Matthias Moetje
