System information
As of DAHDI 2.3.0, the requirement to load dahdi_dummy for a timing
interface no longer exists. The same functionality has now been in-
tegrated into the main dahdi kernel module.
The configuration file defining which modules DAHDI will load is in /etc/dahdi/mod-
ules. To disable loading of extra modules, all we need to do is edit the modules file and
comment out all the modules by placing a hash (#) at the start of each line. When you’re
done, your modules configuration file should look similar to the following:
# Contains the list of modules to be loaded / unloaded by /etc/init.d/dahdi.
#
# NOTE: Please add/edit /etc/modprobe.d/dahdi or /etc/modprobe.conf if you
# would like to add any module parameters.
#
# Format of this file: list of modules, each in its own line.
# Anything after a '#' is ignored, likewise trailing and leading
# whitespace and empty lines.

You can also use dahdi_genconf modules to generate a proper empty
configuration file. The dahdi_genconf application will search your
system for hardware and, if none is found, create a modules file that
does not load any hardware modules.
