Oops.  What version of zaptel do you run?  I would at least try
downloading the latest CVS version.  BTW, what is your version of
FreeBSD?

Another question would be if you need the zaptel timing code.  What
module procuces the warning (meetme, perhaps?) -- start asterisk with
"-vc" to get more information.  Do you intend to use it?  If now,
maybe it would be easier to just disable the module in modules.conf?
