Asterisk is an Open Source software PBX (Private Branch Exchange), developed by Mark Specer of Digium. It allows you to make calls to one another which may have connected to other PSTN (Public Switched Telephone Network) and Voice over Internet Protocol (VoIP). Asterisk runs on Linux, BSD, MacOSX and others. Having built-in features like voicemail, conferencing, IVR, queuing etc.

In this article, we are going to see a basic installation and working of Asterisk 11 in RHEL 6.4/6.3/6.2/6.1/6.0, CentOS 6.4/6.3/6.2/6.1/6.0, Fedora 18,17,16, Ubuntu 12.10/12.04/11.10, Linux Mint 14/13 and Debian Linux Operating Systems.

1. Preparation for Installation

First, you make sure that your system is up-to-date, if not try to update the system and then install dependencies packages using “yum command” and “apt-get command“, before installing Asterisk on your system.

On RHEL/CentOS/Fedora
# yum -y update
# yum install -y make wget openssl-devel ncurses-devel newt-devel libxml2-devel kernel-devel gcc gcc-c++ sqlite-devel

Turn Off SELinux by changing the line “enforcing” to “disabled” in /etc/selinux/config file.

SELINUX=disabled

Once you disabled SELinux, you need to reboot the system.

reboot
On Ubuntu / Linux Mint / Debian
# su root
# apt-get update && apt-get upgrade -y && reboot
# apt-get install build-essential wget libssl-dev libncurses5-dev libnewt-dev  libxml2-dev linux-headers-$(uname -r) libsqlite3-dev

2. Downloading DAHDI, LibPRI and Asterisk Tarballs

Download the source tarballs, these following commands will download current release of DAHDI 2.6, LibPRI 1.4 and Asterisk 11.

# cd /usr/src/
# wget http://downloads.asterisk.org/pub/telephony/libpri/libpri-1.4-current.tar.gz
# wget http://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/dahdi-linux-complete-current.tar.gz
# wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-11-current.tar.gz

Next, extract the files from source tarballs using “tar command” as shown below.

# tar zxvf dahdi-linux-complete-current.tar.gz
# tar zxvf libpri-1.4-current.tar.gz
# tar zxvf asterisk-11-current.tar.gz

3. Configuring, Compiling And Installing

Go to the each directory from where you have downloaded and extracted the packages and start running the following commands to install DAHDI, LibPRI and Asterisk.

Installing DAHDI.
# cd /usr/src/dahdi-linux-complete-2.6.2+2.6.2/
# make && make install && make config
Installing LibPRI
# cd /usr/src/libpri-1.4.14/
# make && make install
Installing Asterisk

Next, run the “configure” script will vary depending upon whether your system is 32-bit or 64-bit. In the middle, when “menuselect” command executes, select your desired options and then hit “Save and Exit” option and the installation will continuous.

Run this command if you’re installing Asterisk on a 32-bit OS.

# cd /usr/src/asterisk-11.3.0/
# ./configure && make menuselect && make && make install && make samples && make config

Run this command if you’re installing Asterisk on a 64-bit OS.

# cd /usr/src/asterisk-11.3.0/

    Better to use yum on centos/fedora seeing as the repo is available for these distros.

  2. cochtan says:

    one important thing is missing – PERL, so before reboot step use also this command:

    yum install perl

    Good luck to all Asterisk people ;-)
