I'm setting up a Linux machine to act as router, firewall and DNS for our company. We're going to start with a 64K ISDN line. Does anyone have any recommendations for an ISDN board? I have information on a SpellCaster for a little over $500. It looks like the board can be used for 64K or 128K ISDN. Thanks in advance, -Matt Avery- A.S.E. Technologies
