I have a stack (~10) PCI ISDN Cards from AVM, then are the "FritzCard PCI V2" series cards, so no in-built audio controllers, but as long as your machine is faster than a PIII then you can do it all in software.

I have used up to 3 of these stacked up in my Asterisk PBX to then connect them up to the phone lines for dial in & out lines.

Selling them for $10 each. PM me if you are interested.

So each card takes one ISDN line and two channels correct?

Yes, a standard Basic Rate ISDN line has two B channels (64KB or one active phone line per channel) and one D channel (signalling, caller id etc). I had in a box 3 AVM cards and one FXO Wildcard (for timing, not for anything else). I found the inbuilt timing of Asterisk "okish" but when I went to the external timing source of the generic X100P FXO wildcard then all those "echo" problems went away.

A primary Rate ISDN card has 30 B and 1 D channels, but I don't have any of those cards, only Basic Rate cards.

Could be use for Data/Internet, but ISDN Data is WAY too expesnive in comparison to ADSL or other broadband solutions, and slower.
