ook for timing to work correctly with ztdummy. you have to do a few things.

1 cd /usr/local/etc/rc.d and edit the zaptel script. as it is missing ztdummy 
in the module loads

on the end of the first line of modules before the " put ztdummy.ko and after 
the first " on the next line.

then you have to build a new kernel with the setting "options HZ=1000

once you have done these 2 steps ztdummy should work.

the other issue is you need to streamline your install by disabling modules 
you dont need.Look at the modules.conf and learn to disable modules. this 
will help lower some resourcec. also if you dont need it do not install h323 
and postgress/radious server. its all about stream lining your build.

if you need help with this let me know I can walk you threw this.
