If you are starting from a preinstalled CentOS server:

yum groupremove 'DNS Name Server'
yum groupremove 'Editors'
yum groupremove 'Legacy Network Server'
yum groupremove 'Mail Server'
yum groupremove 'Network Servers'
yum groupremove 'System Tools'
yum groupremove 'Text-based Internet'
yum groupremove 'Web Server'
yum groupremove 'Windows File Server'

yum remove yum-updatesd cups cups-lpd redhat-lsb autofs pcsc-lite smartmontools cpuspeed avahi

ln -sf /usr/share/zoneinfo/America/Phoenix /etc/localtime

Now skip the next section…

Do a Minimal Install of Centos 5 x64.

I generally disable IPv6 since I've never used it on a PBX.

After the reboot:

yum update -y

then reboot again.

Disable selinux:

setenforce 0

vim /etc/selinux/config

SELINUX=disabled

vim /etc/sysconfig/iptables

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8088 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT

service iptables reload

iptables -nL

Here we add the RepoForge Repository (x64) needed to install mpg123:

wget http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm
rpm -ivh rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm
rm -f rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm

Now e disable the repo so it doesn't pollute anything later:

vim /etc/yum.repos.d/rpmforge.repo

enabled=0

Digium now provides separate repositories for different Asterisk versions (1.4, 1.6, 1.8 and 10).

Once you install an Asterisk version, its repo will be enabled permanently.

Check for updates and additional (64-bit) packages here and Asterisk 10 packages here.

yum install --enablerepo=rpmforge dnsmasq mpg123

rpm -Uvh http://packages.asterisk.org/centos/5/current/x86_64/RPMS/asterisknow-version-2.0.0-4_centos5.noarch.rpm

http://www.voip-info.org/wiki/view/Asterisk+addon+asterisk-addons

The asterisk-addons and asterisk-sounds-extra packages are optional. They include MySQL support for call detail records and MP3 support for Music on Hold (MOH) as well as additional pre-recorded sounds.

The following command also installs ulaw formatted sounds to reduce transcoding and documentation (at the expense of disk space).

yum install --enablerepo=asterisk-10 asterisk asterisk-configs asterisk-addons \
asterisk-sounds-core-en-ulaw asterisk-sounds-extra-en-gsm asterisk-sounds-extra-en-ulaw \
dahdi-tools dahdi-tools-doc

Once installed, you can search for additional asterisk-related packages using a web browser to the repo URLs or at the command line with YUM:

yum search asterisk

yum update

If you're 'virtual', take a snapshot or backup now!

• Asterisk GUI is a lightweight tool appropriate for appliances.
• For safety and security, make a backup of the (default) Asterisk configuration
• The first time you use the GUI, much of the configuration is modified.
• If something goes wrong, just copy the original folder back and re-run the GUI login.

yum install asterisk-gui

reboot

cp -avr /etc/asterisk /etc/asterisk.orig

Be sure the firewall is open on port 8088.

Replace xxx.xxx.xxx.xxx with the IP of your PBX.

http://xxx.xxx.xxx.xxx:8088/static/config/index.html

The default username and password are admin / password.

After logging in and changing the password, reboot.

reboot

See Asterisk-GUI Configuration.

yum install asterisk-addons freepbx*

reboot

Be sure the firewall is open on ports 80 and 443.

Replace xxx.xxx.xxx.xxx with the IP of your PBX.

http://xxx.xxx.xxx.xxx

The default username and password are admin / admin.

See FreePBX Configuration.
