I would recommend stopping asterisk (/etc/init.d/asterisk stop)
/etc/init.d/zaptel stop (unload all modules)
modprobe zaptel; modprobe ztdummy (in the case that you don't have
another card for a timing device)
/etc/init.d/asterisk start


If it is a relatively slow box, try getting the exact sound files you will
be playing back, if you have the space (make menuselect).
