Go2Linux | Linux Operating System

I am starting to work with Asterisk which is a Linux VoIP PBX, that lets you even send your minutes traffic, to VoIP gateways, and therefore one more time Linux is helping us lower the costs of maintaining an office.

As a first thing I tried to install it from repositories both on Debian and CentOS.

Let's start with Debian.

Once you have installed Debian

Just enter as root:

apt-get install asterisk

Then configure your sip.conf and extensions.conf as minimum, then edit the file:

/etc/default/asterisk

and change the option to start asterisk at boot from "no" to "yes"

Now on CentOS

First install CentOS

Then create this file

/etc/yum.repos.d/atrpms.repo

with this content on it.

[atrpms]
name=CentOS $releasever - $basearch - ATrpms
baseurl=http://dl.atrpms.net/el$releasever-$basearch/atrpms/stable
gpgkey=http://ATrpms.net/RPM-GPG-KEY.atrpms
gpgcheck=1

Once that is done enter:

yum install asterisk

You will this output:

Complete!

In this case you just need to configure

/etc/asterisk/sip.conf

and

/etc/asterisk/extensions.conf

according to your needs, and you are done.

On both systems you can start or stop asterisk with

/etc/init.d/asterisk [start, stop, restart]
