I tried the 0.60 version today with a Fritz!Card ISDN PCI on Windows XP.<br />
It was amazing: no drivers or configuration needed to listen to the Asterisk Demo IVR, and the voice quality was good too!<br />
Alas, it can't replace Linux + TDM cards since most voice modems - though available through chan_tapi - are half duplex. But perhaps someday there’ll also be a ZaptelWin32 ;-)<br /><br />
Does anybody know if there’s a spandsp-port for Windows as well?
