asterisk users - Nov 2007 - OT - Which TAPI driver to use ?

Hi,

I'm trying to use latest versions of ActivaTSP and Asttapi with an
Astmanproxy-enabled 1.4 Asterisk.
Up to now, I can't find a way to teach Outlook 2002 how to use any of those
TAPI drivers: when using "Call this contact" in Outlook Contacts pane,
I
can't see and select any TAPI driver.

Beside that, I'm wondering how those software compare and if they are usable
today.
