Install Asterisk on CentOS

Step1: We need to install some required packages. Fro this login as root and type the following in the terminal:

yum -y install gcc gcc-c++ kernel-devel bison openssl-devel libtermcap-devel ncurses-devel doxygen curl-devel newt-devel mlocate lynx tar wget nmap bzip2 mod_ssl crontabs vixie-cron speex speex-devel unixODBC unixODBC-devel libtool-ltdl libtool-ltdl-devel mysql-connector-odbc mysql mysql-devel mysql-server php-mysql php-mbstring php-mcrypt flex screen bison libtermcap libtermcap-devel newt newt-devel ncurses ncurses-devel

Step2: Create a new file in a directory /etc/yum.repos.d with a name "centos-asterisk.repo" and put this text there:

[asterisk-tested]
name=CentOS-$releasever - Asterisk - Tested
baseurl=http://packages.asterisk.org/centos/$releasever/tested/$basearch/
enabled=0
gpgcheck=0
#gpgkey=http://packages.asterisk.org/RPM-GPG-KEY-Digium

[asterisk-current]
name=CentOS-$releasever - Asterisk - Current
baseurl=http://packages.asterisk.org/centos/$releasever/current/$basearch/
enabled=1
gpgcheck=0
#gpgkey=http://packages.asterisk.org/RPM-GPG-KEY-Digium

Now create another file with a name "centos-digium.repo" and put the text:

[digium-tested]
name=CentOS-$releasever - Digium - Tested
baseurl=http://packages.digium.com/centos/$releasever/tested/$basearch/
enabled=0
gpgcheck=0
#gpgkey=http://packages.digium.com/RPM-GPG-KEY-Digium

[digium-current]
name=CentOS-$releasever - Digium - Current
baseurl=http://packages.digium.com/centos/$releasever/current/$basearch/
enabled=1
gpgcheck=0
#gpgkey=http://packages.digium.com/RPM-GPG-KEY-Digium

STEP3: now simply run this command: yum -y install asterisk16 asterisk16-configs asterisk16-voicemail dahdi-linux dahdi-tools libpri
