Asterisk Essentials Training

Learn Asterisk online at your own pace.

The Asterisk Essentials Training video course is designed to rapidly guide a new user through the installation and basic configuration of Asterisk. Key telephony concepts are introduced, explained, and implemented. The course is heavily example-based, with a focus on the practical knowledge required to successfully administer an Asterisk system. Though some time is given to architecture and theory, we've only included the most helpful information. We've left out the non-essentials so that you can get up-to-speed with Asterisk as quickly as possible. Best practices are described throughout, and many examples are supported with Asterisk documentation.

The Asterisk Essentials Training course will teach you the most important things you need to know to install and administer an Asterisk system. It will also start you on the path of deeper Asterisk knowledge. The course includes several references to outside resources for additional information and further learning.

System Requirements

It's easy to get started with Asterisk Essentials! All you'll need to begin is a flash-enabled browser and speakers or headphones. You can learn a lot just by watching and listening to the videos, but we think you'll get the most from the class if you try out the examples yourself. We recommend that before you start, you get access to a Linux system where you can run Asterisk. You'll eventually want to connect a softphone to Asterisk, so it would be ideal if your system were on the same network as your Asterisk system. But don't worry if you can't manage that - we give some guidance for firewall configuration in the course. And even if you can't connect for all the examples, you'll still learn the basic concepts by following along with our examples.

In the Asterisk Essentials course, we cover a lot of information very rapidly. We don't recommend that you try to go through the whole course in just a single session. You're likely to learn the most if you watch 1-2 chapters at a time, over a period of about two weeks. Of course, you're able to watch each chapter more than once, so don't hesitate to review content that is confusing or that lays the foundation for more advanced topics. You may also find it beneficial to review earlier chapters once you have finished later chapters and have a better understanding of the concepts covered.

We've arranged the chapters so that if you're an Asterisk novice, you can follow them in order and learn all the essentials in a logical progression. However, we encourage you to view the chapters in whatever order makes the most sense to you. You can start with the topics you want to know the most about and if the contents are too advanced you can always back up and watch earlier videos to learn more fundamental concepts. We also recommend watching the videos that cover content you may already be familiar with. You may find that you'll learn something new and helpful.
