But you don't know if it will work. IRQ is just part of the problem,
latency and the fact it's just traveling on your MB is another.

Then just buy one with just one card, or sell the 2 cards you will not
be using on eBay :)

Then get some POTS, since your PRI and/or T1 will go down one way, and
when the problem is outside wiring then both the T1 and the PRI will
go in most cases, specifically if they come in on fiber. The questions
is only when and how often.

No, in the beginning you asked because you don't have the experience
so folks like myself that do have the experience answered. It might
work for you, no one knows and you THINK it will work, it's a hit and
miss, stability is huge issue, thats where experience comes in. If you
want something that I or the other people here just think works, then
just get an ATA. If you want something we have experienced and know
that it works, then get a channel bank.
