:) I doubt it. The zaptel driver for FreeBSD isn't up-to-date with the
Linux version, so I doubt Zaptel support on FreeBSD will ever be quite
as reliable as Linux.

But if you're curious: the hangs could be forced by restarting the
asterisk server. Sometimes it would survive one restart then crash
on the second. Sometimes it would crash for no reason at all.
