Basically the device files under /dev/zap. 

You can also generate them yourself. Actually you don't need the 
channel files (1..250) Look for 'mknod' in the zaptel makefile. 
Note that you don't have to have access tothose specific device files. 
However if you're on a partition or bind-mount of your own, it is 
probably mounted with the mount option 'nodev', so you can't just run 
mknod yourself successfully.

You will need write access to /dev/zap/ctl . And if you have that, you
might as well have write access to all the device files there . You
don't need a permission to generate new files there. 

Practically, though, you need read access from /dev/zaptel/pseudo
