The first line		tells chkconfig what runlevels the service should be started in by default, as well as the start and stop priority  levels.  If  the		service  should  not,  by  default, be started in any runlevels, a - should be used in place of the runlevels list.  The second line		contains a description for the service, and may be extended across multiple lines with backslash continuation.		you may need to check the priority of postgresql or mysql through : 	ls -la /etc/rc3.d/		then set the priority of the runlevel accordingly, edit a2billing-callback-daemon.rc	# chkconfig: levels S K	in our script : # chkconfig: 2345 80 80			CALLBACK-DAEMON :				Edit a2billing-callback-daemon and change configurations if needed;				install --owner=root --group=root --mode=700 a2billing-callback-daemon /usr/local/bin/				If you are using any Linux Red Hat system based (SYSV):			install --owner=root --group=root --mode=700 a2billing-callback-daemon.rc /etc/rc.d/init.d/a2billing-callback-daemon			chkconfig --add a2billing-callback-daemon && chkconfig a2billing-callback-daemon on		else:			You have to adapt a2billing-callback-daemon.rc script for your system.			service a2billing-callback-daemon start		if you change the place for install 	dont forget to change into the perl script (a2billing-callback-daemon) ->  use lib '/var/lib/asterisk/a2billing/callback-daemon/lib';	and in the rc file -> A2BDAEMON='/var/lib/asterisk/a2billing/callback-daemon/a2billing-callback-daemon'		when the daemon is started you should see [START] into the log file (/var/log/asterisk/a2billing-daemon-callback.log)		-----===========------===========------===========------===========------===========-----							Configure manager-----===========------===========------===========------===========------===========-----You have to enable manager connections on the servers where is runnning the callback daemon.edit /etc/asterisk/manager.conf :	[general]	enabled = yes	port = 5038	bindaddr = 0.0.0.0		[myasterisk]	secret = mycode	;deny=0.0.0.0/0.0.0.0	;permit=209.16.236.73/255.255.255.0	read = system,call,log,verbose,command,agent,user	write = system,call,log,verbose,command,agent,user			This will allow connection from anywhere , so you can be more restrictive using deny, permit 		deny=0.0.0.0/0.0.0.0	permit=**my-ip**/255.255.255.0		That will allow connections only from **my-ip**-----===========------===========------===========------===========------===========-----							Daemon scheduler-----===========------===========------===========------===========------===========-----If you need to run the callback system only at some time of the day you can proceed as follow :	# Type as root :	crontab -e		# Add these lines :		59   9 * * * /etc/a2billing-callback-daemon-start	59  16 * * * /etc/a2billing-callback-daemon-stop		And copy a2billing-callback-daemon-* /etc/.	chmod 755 /etc/a2billing-callback-daemon-*	-----===========------===========------===========------===========------===========-----							Callback-daemon INFO-----===========------===========------===========------===========------===========-----You might be able to view here all the pending and performed callback with their current status.
