Read the specs for the sipura 3000 for example at their site

Anyone can buy one, it just was a good bundle for test.

It definitely works, but there are some issues that someone who has
done it may be able to  discuss. Otherwise, search the mailing list
using google:

bri card  site:lists.digium.com
2.6 kernel site:lists.digium.com

and any other search expressions you can think of. Do the same without
the site: parameter too, replacing it with "asterisk".

googling asterisk bri card brings up a lot of interesting stuff as
does "asterisk 2.6"
