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.
