Asterisk on FreeBSD + ISDN BRI

[Cian Hughes]

Hello all, I am new to this list and to asterisk but would like to  
install Asterisk on a spare box to act as a PBX at home, basically  
I'm going to route most of my calls over IP, but for incoming,  
emergency, toll free, faxes, etc I want to use ISDN (EuroISDN I'm in  
Ireland).
I have one sticking point, I don't really want four BRIs so a quadBRI  
seems like overkill. However I'm still undecided on what card to buy,  
since this is nothing mission critical I would initially like to  
start with a cheap passive card, and if all doesn't go well i'll buy  
something better. Anyway could I please have everyone and anyone's  
experience of ISDN on FreeBSD (with asterisk or similar), what cards  
are supported, what cards work well?

Also has any one managed Direct Inward Dialling rules with ISDN and  
Asterisk on freebsd (I have 4 MSN's that I would like to use)?

Yours Gratefully, Cian.
