-yum clean all
-</file>
-===== Firewall =====
-Pick one of these three firewall options.
-==== iptables ====
-<file>
-system-config-firewall-tui
-</file>
-The following ports need to be opened:
-^Protocol^Ports^Description^

-|TCP|443|HTTPS|
-|TCP|4445|Flash Operator Panel|
-|UDP|5060-5061|SIP|
-|UDP|10000-20000|RTP|
-|UDP|4569|IAX|
-==== Arno's Firewall ====
-[[networking:firewall:arno_s_firewall|Arno's Firewall]]
-==== No Firewall ====
-<file>
-service iptables stop
-chkconfig iptables off
-service ip6tables stop
-chkconfig ip6tables off
-</file>
-===== selinux =====
-Disable selinux:
-<file>
-vim /etc/selinux/config
-</file>
-<file>
-SELINUX=disabled
-</file>
-<file>
-setenforce 0
-</file>
-===== Time Zone =====
-http://www.php.net/manual/en/timezones.php
-<file>
-ln -sf /usr/share/zoneinfo/America/Phoenix /etc/localtime
-</file>
-===== PHP Settings =====
-==== Time Zone ====
-<file>
-vim -c 946 /etc/php.ini
-</file>
-Uncomment and set PHP timezone:
-<file>
-date.timezone = America/Phoenix
-</file>
-==== Upload File Size ====
-<file>
-vim -c 878 /etc/php.ini
-upload_max_filesize = 20M
-</file>
-===== Install PBX Software =====
-==== Asterisk v1.8 ====
-<file>
-wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-1.8-current.tar.gz
-tar zxvf asterisk-1.8-current.tar.gz
-cd /usr/src/asterisk-1.8*
-make clean
-./configure && make menuselect
-</file>
-Select all addons.  I believe these are all needed or recommended for FreePBX.  Select base and addon sounds.  I suggest ulaw as they sound better than gsm especially if you are using ulaw as your default codec.  I usually just check both.  Then make sure to press the "save" button afterwards.
-:!: If upgrading Asterisk on an already running FreePBX system do NOT run make samples.
-<file>
-make && make install && make samples
-</file>
-Create an 'asterisk' user.  The user may already exist but this won't hurt:
-<file>
-useradd -c "Asterisk PBX" -d /var/lib/asterisk asterisk
-</file>
-The following directory may already exist but just to make sure:
-<file>
-mkdir /var/run/asterisk
-</file>
-Set ownership of various folders:
-<file>
-chown -R asterisk /var/run/asterisk
-chown -R asterisk /var/log/asterisk
-chown -R asterisk /var/lib/asterisk/moh
-chown -R asterisk /var/lib/php/session
-</file>
-Adjust the manager interface username and password:
-<file>
-vim /etc/asterisk/manager.conf
-</file>
-Add a stanza like:
-<file>
-[admin]
-secret = your-manager-password
-deny=0.0.0.0/0.0.0.0
-permit=127.0.0.1/255.255.255.0
-read = system,call,log,verbose,command,agent,user
-write = system,call,log,verbose,command,agent,user
-</file>
-==== Music on Hold ====
-Here we create a symbolic link so that both FreePBX and Asterisk will find and store MOH files in the same place:
-<file>
-ln -s /var/lib/asterisk/moh /var/lib/asterisk/mohmp3
-</file>
-Asterisk and FreePBX now only use .wav files for MOH so install mpg123 for converting uploaded mp3's to wav's:
-<file>
-cd /usr/src
-wget http://sourceforge.net/projects/mpg123/files/mpg123/1.13.4/mpg123-1.13.4.tar.bz2/download
-tar -xjvf mpg123-1.13.4.tar.bz2
-cd mpg123-1.13.4
-./configure && make && make install
-ln -s /usr/local/bin/mpg123 /usr/bin/mpg123
-</file>
-==== Web Server ====
-Here we set the web server to run as the user 'asterisk' and group 'asterisk'.
-<file>
-sed -i "s/User apache/User asterisk/" /etc/httpd/conf/httpd.conf
-sed -i "s/Group apache/Group asterisk/" /etc/httpd/conf/httpd.conf
-</file>
-==== MySQL Configuration ====
-=== Start MySQL ===
-<file>
-service mysqld start
-</file>
-=== Create Databases and Tables ===
-<file>
-cd /usr/src/freepbx-2.10.0                       # adjust version if necessary
-mysqladmin create asterisk
-mysqladmin create asteriskcdrdb
-mysql asterisk < SQL/newinstall.sql
-mysql asteriskcdrdb < SQL/cdr_mysql_table.sql
-</file>
-=== Configure MySQL Security ===
-<file>
-mysql
-</file>
-Run these MySQL commands and adjust for your own password:
-<file>
-GRANT ALL PRIVILEGES ON asteriskcdrdb.* TO asteriskuser@localhost IDENTIFIED BY 'your-password';
-GRANT ALL PRIVILEGES ON asterisk.* TO asteriskuser@localhost IDENTIFIED BY 'your-password';
-flush privileges;
-exit
-</file>
-Finally, we set the MySQL root password.  **Don't forget it!**
-<file>
-mysqladmin -u root password 'your-mysql-root-password'
-</file>
-==== Install FreePBX ====
-Get the latest released version.
-<file>
-cd /usr/src
-wget http://mirror.freepbx.org/freepbx-2.10.0.tar.gz     # adjust version if necessary
-tar zxvf freepbx-2.10.0.tar.gz
-</file>
-:!: MySQL should still be running...
-Start asterisk.  You can ignore warnings, errors, and notices for now:
-<file>
-/usr/sbin/safe_asterisk
-cd /usr/src/freepbx-2.10.0
-./install_amp
-</file>
-You will be asked various questions which will be used to populate /etc/amportal.conf.
-Use the defaults, mostly, but change:
-^Variable^Value^
-|AMPMGRUSER|admin|
-|AMPMGRPASS|password you set when editing manager.conf above|
-|AMPDBPASS|password you chose when configuring MySQL security above|
-|AMPWEBADDRESS|the IP address of your PBX|
-Now we delete a few configuration files that may interfere with FreePBX:
-<file>
-rm -f /etc/asterisk/{sip_notify.conf,iax.conf,logger.conf,features.conf,sip.conf,extensions.conf,ccss.conf,chan_dahdi.conf}
-</file>
-==== MySQL CDR Configuration ====
-<file>
-vim /etc/asterisk/cdr_mysql.conf
-loguniqueid=yes             # add to [Global] section which you may need to also un-comment
-</file>
-==== Services Startup ====
-Enable Apache, MySQL and FreePBX to autostart on boot:
-<file>
-chkconfig httpd on
-chkconfig mysqld on
-echo /usr/local/sbin/amportal start >> /etc/rc.local
-</file>
-:!: Reboot now!
-===== Using FreePBX =====
-:!: Before using FreePBX, you have to visit the configuration page at: http://IP.of.PBX
-:!: Click "Apply Configuration Changes"
-:!: Reboot again
-==== Defailt Credentials ====
-^Function^Username^Password^Comment^
-|FreePBX|admin|admin| |
-|Voicemail & Recordings (ARI)|<none>|<none>|Use the FreePBX admin console to enable|
-==== Configuration ====
-The FreePBX administration console: http://IP.of.PBX
-=== Enable ARI Administration ===
-//FreePBX -> Settings -> Advanced System Setup ->//
-  * User Portal Admin Username -> your-ari-admin-username
-  * User Portal Admin Password -> your-ari-admin-password
-Save each change and click Apply Configuration.
-===== Troubleshooting =====
-==== FreePBX Post Install Tips ====
-http://www.powerpbx.org/book/export/html/255
-==== Asterisk Manager Interface ====
-Verify that the username and password in /etc/asterisk/manager.conf and /etc/amportal.conf match.
-http://www.freepbx.org/support/documentation/faq/changing-the-asterisk-manager-password
-==== Pear DB ====
-If you see an error during FreePBX installation like:
-<file>
-Checking for PEAR DB..FAILED
-</file>
-try:
-<file>
-pear install DB
-</file>
-then re-run:
-<file>
-./install_amp
-</file>
-==== Remote Extensions ====
-:!: If you enable remote access to your PBX, **secure it!**
-:!: NAT is a real hurdle for SIP.  The best way to deal with NAT issues is to not use NAT, if possible.  NAT on both ends may not be worth attempting.
-=== IAX Protocol ===
-:!: Using phones with IAX protocol support is a good alternative if the PBX is behind NAT.
-:!: IAX protocol is pretty much Asterisk-specific.
-If your PBX is behind NAT, forward the single UDP port 4569 from your NAT firewall in to the PBX.
-=== SIP Protocol ===
-http://www.freepbx.org/support/documentation/howtos/howto-setup-a-remote-sip-extension
-If your PBX is behind NAT and you'd still like to try getting remote SIP extensions to work:
-<file>
-vim /etc/asterisk/sip_nat.conf
-localnet=192.168.1.0/255.255.255.0      #your local network
-externhost=your.fqdn.hostname           #your resolvable host name
-fromdomain=your.fqdn.domain.name        #your domain mane
-nat=yes
-qualify=yes
-externrefresh=10
-canreinvite=no
-asterisk -rx reload                     #reload Asterisk configuration
-</file>
-==== PHP Memory Limit ====
-This should be the default:
-<file>
-vim -c 457 /etc/php.ini
-</file>
-<file>
-memory_limit = 128M
-</file>
-==== Re-Install Just FreePBX ====
-<file>
-amportal stop
-rm -f /etc/asterisk/{sip_notify.conf,iax.conf,logger.conf,features.conf,sip.conf,extensions.conf,ccss.conf,chan_dahdi.conf}
-/usr/sbin/safe_asterisk
-cd /usr/src/freepbx-2.10.0
-./install_amp
-</file>
-Visit the configuration page at: http://IP.of.PBX
-Click “Apply Settings”
-Reboot
