OpenBSD and FXO Cards

Hi everyone,

I installed Asterisk 1.0.9 on my OpenBSD 3.6 Box. Everything
works fine! Now I want connect my Analog Line to my Asterisk
Box. Has anyone experience with this under OpenBSD?
Is there any FXO Card that works under OpenBSD 3.6?

Thanks for your help!

External devices are also welcome. But what I read about the
Sipura SPA-3000 is that it works well as standalone. Is there any
external device works well with Asterisk?

Many thanks!
