title: start asterisk autometically when system got restarted
body: <p>I have installed asterisk 1.4 on linux centOS 6.2. and I have also made entry to start asterisk in <strong>/etc/rc.local</strong> as <code>/usr/bin/asterisk</code>.
  but it did not worked. When the system starts, it shows that asterisk service has started but actually it's not working i.e. command <code>asterisk-vvvvr</code> does not work.</p>
  
  <p>If I start the service manually after boot up the system, it works perfectly. can someone tell why asterisk is not working via <strong>rc.local</strong> file and I can start the asterisk automatically at system start up.</p>
  
  <p>thanks in advance.
  PS: I have already tried a lot of methods by googling but there is still problem.</p>
