In this article, we have given you the steps for installing Asterisk in your Linux Machine.

1) Create a new directory "asterisk" under your default source files path,
# mkdir /usr/src/asterisk

2)Inside "asterisk" folder, you need to download or copy asterisk source file for compilation.
# cd /usr/src/asrerisk
# wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-1.8.4.tar.gz

(You can download older versions of asterisk from asterisk.org | Make sure you are connected with internet)

3) The .tar file must be untar (unzip) in order to execute the source file/
# tar zxvf asterisk-1.8.4.tar.gz

Before installing asterisk, you need to run several dependencies through YUM command or by RPM package, to execute the asterisk installer
Examples:
#yum install gcc
#yum install gcc-c++
#yum install glibc
#yum install glibc-devel
#yum install ncurses
#yum install ncurses-devel
#yum install openssl
#yum install openssl-devel
#yum install zlib
#yum install zlib-devel
#yum install bison
#yum install kernel-devel

( if you have missed any dependencies, You need not to worry as asterisk scripts on compiling-step4, generates error with the name of the dependencies required, and you can again do a "yum install DEPENDENCY" to get all the required material.

4) After Installing dependencies, run
# ./configure 
(This step checks the libraries and dependencies required for compiling | Install missing dependencies at this point, if required)

5) #make menuselect 
(This step is optional , it is needed to select the specific modules)


6) Final commands assuming the built complete successfully.
# make
# make install
# make samples

Then run asterisk service

# asterisk -vvvc

You will Enter in the CLI mode of asterisk after the above command.

LINUX NETWORK SETUP


In Linux network setup can be done in two ways. In the first phase of our discussion we will discuss Dynamic IP, and in the second phase we will discuss static IP.
