They have unequivocally dropped support for these cheap cards. They suck 
anyway, but this isn't to say you can't play with one.... I still do, after all.

Indeed, mine is a clone, and they are equally unconcerned about my problems 
with it. '-)

This may be true, but I believe it's more because the cards, as every one will 
tell you straight up (unless they are selling you the card, of course) are of 
poor quality and design.

Yep. There are driver issues, voltage/signalling problems... and in the end, 
even if working, they won't sound good. There's a reason they are, like, $10 on 
Ebay.

Basically, they are decent winmodems (if such a thing is possible)... that they 
can be used for telephony is a fluke.

Yep. Definitely a way to get your hands dirty. 

By the time you figure out what you need to know to get a decent answering 
machine with your new toy, you can go buy real hardware and make telephony 
appliances. 

Meanwhile, anyone likely to be of any real help while you experiment, is doing 
just that, and has no interest in watching/helping you suffer, from what I've 
gathered.

My time figuring out the first glitch between my card and the (sort of) 
supporting driver would have been saved/paid for by buying a real FXO/FXS card 
initially. I didn't do that, but you, or the OP, still can. And, finally, if I 
want to ever *use* this experiment in the real world, I'll have to replace the 
X100p with a decent sounding device anyway.

Cheers,
