That is one option.  The new line Digium cards are on par with Sangoma as
far as IRQ issues.

I really like Sangoma's lifetime warranty though.  I don't think Digium has
countered that bold move.

I would try the RMA and if that doesn't work, you can always pickup a decent
last year's model server at
http://www.surpluscomputers.com/featured-hardware/cg-69/servers.html

For a basic asterisk server or PBX with nothing special going on, any of
these servers are more than enough, even overkill.

No affiliation, I have to say the shipping is high and they are slow to ship
but the prices are great, never had an issue with any of their boxen
(dozens, knock on wood....)
