VoIP for Dummies - Asterisk VoIP Server setup with Android, iOS, Win Apps - Using Fully Open Source Server and Clients

In this course, we will setup a VoIP server and the client devices and the clients can make calls in between them using the VoIP server. And no prior experience is required.

VoIP or Voice over Internet Protocol is a technology that allows you to make phone calls across devices without using the normal analogue phone connection. So your calls will be placed across internet and the normal phone lines are not required.

VoIP allows you to make calls from a computer, a mobile phone which is connected to internet, or a normal phone which is connected to a specific adapter called the 'VoIP Adapter'. The major benefit is that since this call is placed over internet, you don't need a separate line or a dedicated line in-order to make the call. Just an internet connection is more than enough to make a call.

If you are a business owner trying to get down the cost of communication at your office, or you are trying to setup a vast call based call centre operation or you are a technical enthusiast who  wants to host your own VoIP server and provide this service to your client users, then this is the course exactly for you.

Let me now give you a brief overview of what are the topics that we are going to cover in this course.

In the first session, which is basically a theory session, we will be covering the technology behind VoIP. And we will be covering the architecture and the working of VoIP technology compared to the normal PSTN (Public Switching Telephone Network) that has been there from the beginning.

And in the next session we will be setting up own own ubuntu based VPS server in an Amazon (AWS) ec2 instance. I am preferring Amazon , because they have a very flexible plan and they have an option called 'Free Tier', which we can use free for one year with a very minimal cost if you are keeping your usage in an optimal state.

And after setting up the VPS server, we will installing Asterisk, which is a very popular open source VoIP server software available, and we will be installing it into our VPS server and we will also configure the ports, the specific number of ports that are required for the client devices to communicate with other client devices through the server.

And in the next session, which is an important session, in which we will be configuring the dial plan and the extensions that we are going to use with our server. We will also make configuration to accept audio calls as well as video calls through our VoIP server.

For our VoIP client applications we will be using an application called Linphone. It is also a completely open source application and the advantage is that it is available for all the platforms. For windows, Linux, Mac, Android and iOS device and the source code is completely open. You can download it and customize it as per your needs.

The same configuration settings that you are going to make in this softphone, do the same configuration if you have a physical, hard wired, IP Phone with you. You can enter all these configuration into that and it will also work in the same way as we configure the soft phone clients.

And in the next session, we will be configuring a windows based softphone, which is our linphone. We will be installing it in our windows and we will configure the option so that it can register with the server and make video and audio calls in between devices.

And later, we will configuring it for Android. The same configurations. We will be installing it from the play store in an android device and we will make the configuration so that video and audio calls can be placed.

And after that, we will have it for iPhone We will directly download it from the iPhone App Store and we will be installing it into our iPhone and then we will try to make calls from iPhone to other devices and we will be testing the video calls as well as audio calls across the devices.

Learning and becoming an expert in VoIP technology is actually a very rewarding career because VoIP technology is very extensive so far and there is some time in future where we will discard all those analogue telephone lines and we will rely completely on VoIP based IP telephones. Because we need only a single internet channel , rather than having multiple channels.

So world is evolving into that kind of a technology and VoIP experts are very much required in the market. And by the end of this course, we will be providing with you an experience certificate (Course Completion Certificate), which you will have great benefits, if you are trying for a VoIP based career.

So see you soon in the class room. Let's make our first call ! Have a great day !!

Linux Command Line – From Zero to Expert

Get in the rhythm of the command line as a first step towards Linux System Administration, VoIP and many more areas

Created by Mohammad Nauman - Helping YOU learn software engineering, quickly and easily!


Students: 2260, Price: $29.99

Students: 2260, Price:  Paid

This course is for you if you are new to the Linux Command Line but want to learn it without all the headaches. Linux command line is a cross-cutting skill.  If you are comfortable with the command line, you can learn a lot of different skills very quickly and with minimal hassle.  After taking this course, you will be all set to work with highly useful concepts such as Linux System Administration, setting up architectures for Machine Learning and Deep Learning, work with systems that enable VoIP and many many more areas.

In this course, we will start from scratch. This is a very applied course, so we will immediately start with the command line! We will explain everything through the commands and not bore you with dull slides. In fact, there isn't a single slide in this course!

If you have never worked with Linux before (or installed it), this course will show you how to set it up in a Virtual Machine with minimal effort. If you already have Linux or Mac, you can use that too. Then, we will start from zero and get you up to the level of expert without dumping too many commands on you.

We take a case study-based approach and motivate why we need the commands we're learning. If there is a command that is typically taught in courses but isn't used too often, we skip it so that you learn only the stuff that will be useful to you.

In this course, we aim to give you the feel of the rhythm behind the command line so that you are in the position to understand the philosophy behind the command line and use it to your advantage. Through this approach, we can cover the whole spectrum in less than 3 hours.

There is also a real-time chat system in place for students who enroll in this course. With a free signup, you get access to real-time chat with myself and fellow students who are working to complete this course (or have completed the course before you). We plan on creating this network of like-minded experts who can help each other out and collaborate on exciting ideas together.

What will I learn?

  • Basics of the command line 
  • Working with files and directories from the command line (and understand why you would want to do that in the first place)
  • Applying the commands to solve real problems instead of made-up issues
  • Understand how very simple and easy-to-understand commands work together to solve much bigger and important problems
  • Know keyboard shortcuts that will save you a lot of time and effort when working with the command line
  • Perform operations that simply cannot be done in the Graphical User Interfaces
  • Follow a case study that shows how the command line can be used to download a complete YouTube playlist (and learn quite a few commands along the way)
  • Work with the extremely powerful vi editor and understand why people are so crazy about it (and how it can be useful to you)
  • Learn how the professionals make their command lines look cool (and again, learn a few commands along the way)

About the instructor:

  • Teacher and researcher by profession
  • PhD in Security and a PostDoc from Max Planck Institute for Software Systems, Germany
  • 17+ years of working with computers and 15+ years of teaching experience 
  • 10+ years of working professionally as a Linux System Administrator/VoIP DevOp -- including 5+ years of provable track record on UpWork (with 5.0 star rating there)

Target Audience:

Anyone who:

  • Wants to know why the command line is a necessary tool for anyone working with computers   
  • Has never worked with Linux and wants to know what the fuss is all about 
  • Has worked with Linux or needs to do so but has been avoiding the command line

What you need to know before starting:

  • No prerequisites are assumed.
  • You can take this course even if you have never worked with Linux before.

*** UPDATES ***

  • Added section on remote connectivity and keeping processes running even on disconnect.

VoIP Design and Telephony Fundamentals

Prepare for your VoIP project like a pro

Created by Flavio E. Goncalves - 30+ Years of experience in IT, VoIP and SIP


Students: 814, Price: $99.99

Students: 814, Price:  Paid

In the last year I have thought this course twice to companies who were starting a new VoIP project. It is an interesting training for those who have little knowledge of telephony and voice over IP networks.  We start with conventional telephony, covering analog and digital telephony. In the second section we move to VoIP fundamentals covering dimensioning of circuits and bandwidth, codec selection and legacy integration. Then we cover QoS for routers and switches, in this chapter we have used Cisco routers and switches for the examples and demos, but the concepts can be applied to any vendor.

When I started with open source PBXs in 2004, one of the things I've noticed is, most people working with open source telephony do not have a background on network design. One of the key factors for the success of proprietary vendors is the enforcement of best practices thru their channel partners. You probably won't see a Cisco VoIP project without QoS enabled, but still in these days, most open source projects do not enforce best practices on dimensioning, Quality of Service and integration with the legacy. That's the gap I want to fill with this course.

I believe this training will never be ready, there will always new devices and new technologies to cover. So I plan to update it regularly. As you have lifetime access, you will always receive the updates.

Section 1:

Analog Telephony

This section is key. It is very important to understand the concepts of analog telephony, FXS, FXO and E+M interfaces.  How to integrate a VoIP network with the PSTN (Public Switched Telephone Network).

Digital Telephony

Here we cover T1/E1 networks, CAS (Channel Associated Signaling) and CCS (Common Channel Signaling). Our focus will be in the standard ISDN (Integrated Services Digital Network) used by almost all countries in the world and also MFC/R2 for CAS, often found in Latin America, Africa and China. 

Section 2:

VoIP Fundamentals

Here we will present the basics of VoIP.

Codec Selection

How to select the best codec for your Job.

Channels and Bandwidth Dimensioning

In this chapter you will learn how to calculate the number of channels required given the amount of minutes in the busiest hour. Once you have the number of channels we will use the VoIP calculator to define the bandwidth required.

How to design for Voice Quality

In this section you will learn how to design and measure the performance of your network. You will understand important concepts related to voice quality such as the R-Factor and MOS (Mean Opinion Score). I will point you some utilities capable to measure the voice quality in your network.

Legacy Integration

Only in rare situations you will implement a completely new project. Most of the big projects will require you to integrate with the legacy. Legacy large PBXs, PBXs in the branches, survivability and others. 

Section 3:

In the section 3 we are going to cover QoS (Quality of Service).

Classification and Marking

Covering CoS (Class of Service), DSCP (Differentiated Services Code Point) and Precendence

Fragmentation, Interleaving and Compressed RTP

How to handle slow circuits using fragmentation and interleaving and how to enable cRTP in PPP circuits.

Queueing and Tail Drop

Most common congestion management and avoidance techniques. We will do a demo for the implementation of Low Latency Queuing on Cisco and AutoQoS on switches.

Voice VLANs

Voice VLANs are essential for security and broadcast storm protection. One of the best security features for any network were the phones are open to the public such as Hotels and Universities.

So, in the first section of this course, I will teach you Linux survival skills that you need to have for your Asterisk journey.  

After it, we will start diving into the Asterisk world by compiling Asterisk from source code and then installing it.

Once we are done with the installation part, I will give an architectural view of Asterisk because it’s important to understand the various modules functionality.

And then we will start dial plan programming, I tried to cover most of the asterisk dial plan programming constructs like variables, expressions, contexts and applications etc.

For channels configurations, I have entire section for PJSIP – new SIP channel driver and IAX asterisk native protocol.

 To get more solid foundation in Asterisk dial plan programming, we will build a complete professional Auto-Attendant for commercial grid Asterisk PBX.

 Each section of the course has Quiz, that will help you judge your knowledge gained in section.

And I’ve developed 8 practical Lab exercises for hands on training. Each lab is having its configurations files and instructions. Performing these labs will give the confidence and will help you in real world as well while dealing with Asterisk VoIP platform.

In the end, I love to support my students and always encourage them to ask questions on course discussion area.
