In simple world Asterisk is an open source framework that can be used for building communications applications like IP PBX, VoIP Gateway and other solutions. Asterisk is a open source PBX software packages, which is used to convert normal computer into a communications server.

In this article I am going to explain how you can setup a basic Asterisk server.

Setup Basic Asterisk Server

Follow the below steps to configure basic Asterisk server.

1. Download and Install the Prerequisites packages: First of all you have to download and install prerequisites packages using yum command:

# yum -y install make wget openssl-devel ncurses-devel subversion newt newt-static newt-devel libxml2-devel kernel-devel gcc gcc-c++ mysql sqlite-devel uuid-devel libuuid-devel speex-devel libuuid libxslt uriparser

Now you have to download and install “Jansson” package for Asterisk server.

# cd /usr/src/
# wget http://www.digip.org/jansson/releases/jansson-2.10.tar.gz
# tar -xvf jansson-2.10.tar.gz
# cd jansson-2.10
# ./configure
# make && make install && make check

You will get some output like below:

make[3]: Entering directory `/usr/src/jansson-2.10/test'
make[4]: Entering directory `/usr/src/jansson-2.10/test'
PASS: run-suites
============================================================================

============================================================================
# TOTAL: 1
# PASS: 1
# SKIP: 0
# XFAIL: 0
# FAIL: 0
# XPASS: 0
# ERROR: 0
==================================================================
make[4]: Leaving directory `/usr/src/jansson-2.10/test'
make[3]: Leaving directory `/usr/src/jansson-2.10/test'
make[2]: Leaving directory `/usr/src/jansson-2.10/test'
make[1]: Leaving directory `/usr/src/jansson-2.10/test'
make[1]: Entering directory `/usr/src/jansson-2.10'
make[1]: Leaving directory `/usr/src/jansson-2.10'

Now you have to download the Asterisk, DAHDI and Libpri  package.

Download Asterisk Package

# mkdir -p /usr/src/asterisk
# cd /usr/src/asterisk
# wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-14-current.tar.gz

Download DAHDI and Libpri Package

# wget http://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/dahdi-linux-complete-current.tar.gz
# wget http://downloads.asterisk.org/pub/telephony/libpri/libpri-current.tar.gz

DAHDI stands for Digium Asterisk Hardware Device Interface.

Configure DAHDI

# tar -xvf dahdi-linux-complete-current.tar.gz
# cd dahdi-linux-complete-2.11.1+2.11.1/
# make
# make install
# make config

Install Libpri Package

Libpri package is used to connect to a PRI service.

# tar -xvf libpri-current.tar.gz
# cd libpri-1.6.0
# make
# make install

Install Asterisk Package

Now install Asterisk package following below command:

# cd /usr/src/asterisk
# tar -xvf asterisk-14-current.tar.gz
# cd asterisk-14.5.0
# ./configure --libdir=/usr/lib64

You will get some output like below:

configure: Host CPU : x86_64
configure: build-cpu:vendor:os: x86_64 : pc : linux-gnu :
configure: host-cpu:vendor:os: x86_64 : pc : linux-gnu :

Note :- If you are installing Asterisk on 32-bit operating system then you don’t need to mention library directory.

Now run the below command:

# make menuselect && make && make install && make samples && make config

You will get someput like below:

2. Enable and Start Asterisk Service: Now restart and enable the Asterisk service using below command:

# /etc/init.d/asterisk start
Starting asterisk (via systemctl):                        [  OK  ]

Check Asterisk Status

# /etc/init.d/asterisk status

3. Connect To Asterisk CLI: Now connect to Asterisk CLI mode using below command:

#  asterisk -rvvvv
