Unfortunately, issues in Asterisk 1.2 require us to run the web server process as the same user as asterisk. In this situation, it's easier for us to run httpd as 'asterisk', rather than asterisk as 'httpd', as there's far less configuration that needs to be done.

cd /usr/src
useradd -c "Asterisk PBX" -d /var/lib/asterisk asterisk
chown asterisk /var/lib/php/session/

Change (Copy) MOH directory:
cp -vR /var/lib/asterisk/moh /var/lib/asterisk/mohmp3
chown -vR asterisk.asterisk /var/lib/asterisk/mohmp3
chmod -v 775 /var/lib/asterisk/mohmp3
chmod -v 664 /var/lib/asterisk/mohmp3/*

You need to change User apache and Group apache to User asterisk and Group asterisk.

sed -i “s/User apache/User asterisk/” /etc/httpd/conf/httpd.conf
sed -i “s/Group apache/Group asterisk/” /etc/httpd/conf/httpd.conf

Change the default AllowOverride All to AllowOverride None to prevent .htaccess permission problems.
sed -i “s/AllowOverride All/AllowOverride None/” /etc/httpd/conf/httpd.conf

You also want to change AllowOverride None to AllowOverride All
sed -i “s/AllowOverride None/AllowOverride All/” /etc/httpd/conf/httpd.conf

Before you can do anything to MySQL, you need to make sure it's running:

/etc/init.d/mysqld start
Initializing MySQL database:                               [  OK  ]
Starting MySQL:                                            [  OK  ]

Now, to configure the databases for freePBX:
Note: If mysql admin password is already configured, add "-p" after the command and enter password when asked.  For example, "mysqladmin -p create asterisk"

cd /usr/src/freepbx-2.3
mysqladmin create asterisk
mysqladmin create asteriskcdrdb
mysql asterisk < SQL/newinstall.sql
mysql asteriskcdrdb < SQL/cdr_mysql_table.sql

They also need to be secured, so that not just anyone can access them. freePBX will prompt you for a database password when you do the install. You need to pick that now. We'll assume that you've picked 'asteriskuser' and 'amp109' - you probably shouldn't use these, as they are well known passwords for Asterisk@Home builds. If anyone's trying to attack your machine, they will try this.

mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 8 to server version: 4.1.16

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> GRANT ALL PRIVILEGES ON asteriskcdrdb.* TO asteriskuser@localhost IDENTIFIED BY 'amp109';
Query OK, 0 rows affected (0.00 sec)

mysql> GRANT ALL PRIVILEGES ON asterisk.* TO asteriskuser@localhost IDENTIFIED BY 'amp109';
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> \q
Bye

Now, after all of this, you need to pick a root 'mysql' password. We'll make it 'abcdef'. If you need to do anything else with mysql, you'll need to provide this password.
mysqladmin -u root password 'abcdef'

amportal
Usage: amportal start|stop|restart|start_fop|stop_fop|restart_fop|kill|chownspan style="background-color: #E9ECEF; background-position: 0% 0%">

start: Starts Asterisk and Flash Operator Panel server if enabled
stop: Gracefully stops Asterisk and the FOP server
restart: Stop and Starts
start_fop: Starts FOP server and Asterisk if not running
stop_fop: Stops FOP serverg
restart_fop: Stops FOP server and Starts it and Asterisk if not running
kill: Kills Asterisk and the FOP server
chown: Sets appropriate permissions on files
 

Set FOP to run on startup
nano +52 /etc/amportal.conf
FOPRUN=true

The amportal script is the recommended way to stop and start asterisk:
/usr/local/sbin/amportal stop
/usr/local/sbin/amportal start

Automatic start-up
echo /usr/local/sbin/amportal start >> /etc/rc.local

For some reason it has become necessary to change amportal.conf access restrictions around about FreePBX v2.2.x
chmod 775 /etc/amportal.conf

Ensure services are starting at boot time and reboot
In order to access and use freePBX we will want both Apache (httpd) and MySQL (mysqld) to be started at boot. You can check to see if they are setup to start at boot by using chkconfig:

chkconfig --list httpd
httpd 0:off 1:off 2:off 3:off 4:off 5:off 6:off  

chkconfig --list mysqld
mysqld 0:off 1:off 2:off 3:off 4:off 5:off 6:off

Here we see that both httpd and mysqld have off across the board (runlevels). chkconfig can also be used to turn on a particular service, which you would want to do in this case.
chkconfig httpd on
chkconfig mysqld on
You can now access freePBX with your web browser.

Edit Apache web server for GUI access using a port other than 80 (optional):
nano /etc/httpd/conf/httpd.conf
change "Listen 80" to "Listen 8888" or whatever port you want

/etc/rc.d/init.d/httpd restart

Instead of accessing FreePBX by http://xxx.xxx.xxx.xxx
You now access it by http://xxx.xxx.xxx.xxx:8888

Edit Flash Operator panel so that it is accessible from outside the LAN by leaving the "web_hostname" blank.  Note:  Port 4445 must be forwarded to the asterisk server on the Firewall/Router.

nano +34 /var/www/html/panel/op_server.cfg
web_hostname=
(Ctrl-X>y>ENTER)

The first time you click on the FreePBX Administration link you will be prompted for a username and password. Use admin and admin. CREATE A NEW ADMINISTRATIVE USER IMMEDIATELY AFTER LOGIN.

nano /etc/php.ini
change the “max filesize” from 2M to 20M to allow larger mp3 music on hold files

The following ports needed to be forwarded to the asterisk server for various remote access

Port 80 (Freepbx web access)
Port 4445 (Flash Operator Panel web access)
Port 4569 (IAX remote phone clients)
Port 5059-5061 (registration and proxy server access, default is 5060)
Port 10000-20000 (ports reserved for RTP voice packets for SIP phone conversations by Asterisk)

NOTE: The RTP ports 10000-xxxxx forwarded in the firewall/router need to match the setting in /etc/asterisk/rtp.conf

To adjust gain you run:
/usr/src/zaptel ./ztmonitor 1 –v

Make or receive a phone call on line 1.  Adjust the rx and tx gain in /etc/asterisk/zapata.conf  accordingly, do a “amportal restart” and try again until you get a good range that is not too low and not too high on average.

nano /etc/asterisk/sip_nat.conf
nat=yes
externip=<your fixed external IP> or
;externhost=yourdns.com
localnet=192.168.1.0/255.255.255.0
externrefresh=10

(Ctrl-X>y>ENTER)

Also, when adding the external SIP extension in FreePBX, make sure to change the nat=never default in the configuration to nat=yes for the extension that will be external.

By default, Asterisk/Freepbx installs with full (debug and verbose) logging enabled.  This generates a significant amount of extra write activity to the hard drives and creates a very large "var/log/asterisk/full" log file in a short amount of time.  After the initial settling in period when debug logging is no longer required it is a good idea to disable this to reduce the stress on the drives and extend their life.

nano /etc/asterisk/logger.conf

change
full => notice,warning,error,debug,verbose
to
full => notice,warning,error,verbose

you will need to restart Asterisk or type LOGGER ROTATE at the CLI to get this change to take effect (reload doesn't do it apparently).

Asterisk/FreePBX does not set up a configuration to automatically rotate the log files for some reason.  Kind of suprising.  I only noticed because the /var/log/asterisk/full log file got to 300MB after only a month.  It would probably crash the system after awhile.  Create  the following file.

nano /etc/logrotate.d/asterisk

Now add the following  to make sure the asterisk log files are rotated weekly along with all the other log files.

/var/log/asterisk/messages /var/log/asterisk/*log /var/log/asterisk/full {
   missingok
   notifempty
   sharedscripts
   create 0640 asterisk asterisk
   postrotate
   /usr/sbin/asterisk -rx 'logger reload' > /dev/null 2> /dev/null
   endscript
}

Edit /etc/aliases file  and add a “root: username_to_forward_to” to forward all ‘root’ messages to your personal email address.  Put in the full email address if it is not on the asterisk system itself.
Then run  
/usr/bin/newaliases
to restart the service.

When backups are created in Freepbx, they are located in /var/lib/asterisk/backup and can be copied elsewhwere

If you want to restore a previous configuration, load the backup files into the above directory.  You must first create the “backup” directory or whatever name you want in freepbx backup and restore module.  If Voicemail problems occur after a backup restore, try restoring just the voicemail part.

Create Acronis Workstation 9.1 (or later) recovery DVD on a PC and boot the Asterisk server on it.  Follow instructions to create a hard drive image of the server onto the DVD.  In the event of an emergency when the Asterisk server is corrupted beyond repair, this recovery DVD can restore the server back to the fresh install state.  If it complains about writing to the same DVD disk as it booted from while making the backup, just eject the drive and slide it back in again.  Enable write cache on the 3ware RAID card for faster recovery.

nano /etc/asterisk/sip_notify.conf
[aastra-check-cfg]
Event=>check-sync
Content-Length=>0

(Ctrl-X>y>ENTER)

Then from the asterisk console you can type "sip notify aastra-check-cfg 123", where 123 is the sip phone 

Time settings on the phones should be configured in the aastra.cfg file.  NOTE: System time must be set to UTC otherwise the phones will not recognize it.

cd /usr/src
wget http://superb-west.dl.sourceforge.net/sourceforge/webadmin/webmin-1.300-1.noarch.rpm
rpm -Uvh webmin-1.300-1.noarch.rpm
nano /etc/webmin/miniserv.conf

port=9000

(Ctrl-X>y>ENTER)

service webmin start

to access http://192.168.1.20:9000
user:root
pw:rootpassword

This assumes the Asterisk server is configured for external extensions and the extension configuration in asterisk is configured to be used as an external extension.  Both are described earlier in this guide(sip_nat.conf, nat=yes).

Reset the phone to factory defaults.  All you need to configure in the phone are phone number, callerID, authentication name, password, Proxy IP and Registrar IP.  Leave everything else at default and it should work.  I also changed registration retry timer and BLF subscription period to 120s.

In order to make Aastra phones work outside a Cisco PIX firewall to the Asterisk server inside the firewall, we needed to remove fixup protocol sip 5060, and fixup protocol sip udp 5060 which are both enabled by default.

no fixup protocol sip 5060
no fixup protocol sip udp 5060

In order to make extensions work over VPN’s we had to add the VPN subnets to sip_nat.conf to make the phones on the 192.168.2.0 and 192.168.3.0 subnets work with the Asterisk Server on the 192.168.1.0 subnet.  Here is the whole sip_nat.conf file
