Short for "Digium Asterisk Hardware Device Interface"

The Change

DAHDI is the new name for 'Zaptel' as of May 19th 2008.
The post at http://blogs.digium.com/2008/05/19/zaptel-project-being-renamed-to-dahdi/ details the reason for the change.

Details should be available at http://www.asterisk.org/zaptel-to-dahdi

Configuration Files

/etc/zaptel.conf Becomes /etc/system/dahdi.conf
/etc/asterisk/zapata.conf Becomes /etc/asterisk/chan_dahdi.conf

There are a number of other configuration files under /etc/dahdi .

/etc/dahdi/init.conf

Replaces /etc/default/zaptel (on Debians) and /etc/sysconfig/zaptel (on most other systems) - this is a shell script snippet that is sourced by the dahdi init.d script. All values there are optional (no need to explicitly define TELEPHONY=no). The variable MODULES, however, is no longer read from it. IT is read from:

/etc/dahdi/modules

A list of modules to load. Replaces the variable MODULES from the above configuration file.

/etc/dahdi/genconf_parameters

Fine--tuning parameters for dahdi_genconf (replaces zapconf and also deprecates genzaptelconf).
