Afaik the preferred way is too use zaptel, libpri, asterisk and
asterisk-addons either from the stable branch (cvs co -r v1-0 <modules>)
or from HEAD (cvs co <modules>). You are mixing them. Get one or the
other.

Also make sure your Dell has the latest firmware installed for all
components they offer newer firmware for. Solved some funky problems I
dealt with a while back.

If you get any NMI errors, BIOS memory count that's off and really weird
behavior, take out the memory modules and reseat them properly. Same
applies to the CPU. Might as well do any cards while you are at it. And
if you are really suspicious, check the seating of the cables too.
Reseating the CPU and memory modules solved all our remaining problems.
I will refrain from making obvious comments about Dell's quality
control :)
