How many lines are you talking about?  In light of your budget issues, I
would switch to quality SIP provider and have my numbers ported.

That would most likely be cheaper in the long and short run, and more
reliable depending on the vendor and your internet connection.

Other options are going back to old versions of Asterisk.  What version are
you running?  What was wrong with the version from 1.5 years ago?  Maybe
your card likes being a Zap device, rather than a DAHDI.

You could make a cron job to reboot the machine at midnight, daily.

I have a box full of Digium cards with all sorts of modules, I could "sell"
you what you need for the price of postage but I really think SIP is your
silver bullet.

I push over $12k a week of outbound traffic through VoicePulse (never would
of considered this a year or two ago) with absolutely no issues.

Vitelity is pretty good and low priced as well but I have never used them
anywhere near the above.

Best of luck in this economy,
