\subsubsection{Asterisk Main Configuration File}

Below is a sample of the main Asterisk configuration file,
asterisk.conf. Note that this file is not provided in
sample form, because the Makefile creates it when needed
and does not touch it when it already exists.

\begin{verbatim}
[directories]
; Make sure these directories have the right permissions if not
; running Asterisk as root 

; Where the configuration files (except for this one) are located
astetcdir => /etc/asterisk

; Where the Asterisk loadable modules are located
astmoddir => /usr/lib/asterisk/modules

; Where additional 'library' elements (scripts, etc.) are located
astvarlibdir => /var/lib/asterisk

; Where AGI scripts/programs are located
astagidir => /var/lib/asterisk/agi-bin

; Where spool directories are located
; Voicemail, monitor, dictation and other apps will create files here
; and outgoing call files (used with pbx_spool) must be placed here
astspooldir => /var/spool/asterisk

; Where the Asterisk process ID (pid) file should be created
astrundir => /var/run/asterisk

; Where the Asterisk log files should be created
astlogdir => /var/log/asterisk
