Upgrading users, please note that some incompatible changes have occurred
since 1.2 (mainly removal of deprecated commands, but some defaults have
changed, and DTMF has been heavily overhauled); the following files have
more information:

${PREFIX}/share/doc/asterisk/CHANGES
${PREFIX}/share/doc/asterisk/UPGRADE.txt

Simplified sample configuration is provided in ${SYSCONFDIR}/asterisk;
the full set is available in ${PREFIX}/share/examples/asterisk/default.

To have Asterisk start at boot time, you may insert the following
into ${SYSCONFDIR}/rc.local:

if [ -x ${PREFIX}/sbin/safe_asterisk ]; then
        echo -n ' asterisk';   ${PREFIX}/sbin/safe_asterisk
fi

This uses safe_asterisk which monitors for abnormal termination
and restarts the daemon, and also creates the directory for the
control socket (astrundir in ${SYSCONFDIR}/asterisk/asterisk.conf).
If you prefer not to use safe_asterisk, you will need to do this
yourself.
