Fax (t.38) is a bit different in that there is a widely accepted
protocol to handle it.  That being said, I usually go analog lines from
a provider for fax lines.  Maybe I'm old fashioned.

analog devices

If I'm going to have trouble with modems, I guess I should assume I'm 
going to have problems with fax machines and such as well? I really made

a bad assumption on this one I guessed. So you thing I would have 
trouble with any analog device that is transmitting data? Does anyone 
have any good experience with a setup that doesn't require a PRI or POTS

lines. I guess I'm trying to do the impossible here.
