This course is for you if you are new to VoIP and want to learn how to setup Asterisk, the flexible and extremely popular open-source platform for enabling VoIP based systems. 

In this course, we will start from the very scratch. This is a very applied course, so we will only look at one brief theory lesson and then start building asterisk from the source. I will explain all the concepts as they come along. You only need a basic understanding of the Linux command line. I will try to explain all the asterisk-related commands in this course. 

We will also set up FreePBX a GUI-based system that allows you to handle your asterisk installation in an easy-to-use and powerful interface. Once you set it up, even a moderately knowledgeable client can use it to set up their systems and perform their day-to-day operations thus making your life as an administrator much easier. 

In this course, I will explain all the steps necessary to setup Asterisk, dial a hello world call to this system, and then set up FreePBX. Afterward, we will set up two local extensions that will allow you to create an exchange within an office environment. Since this is a basic course, we will not cover inter-organization VoIP such as DIDs, SIP trunks etc. However, we work in a way that after completing this course, these other aspects will also be easy for you to set up.
