What is VoIP?

VoIP stands for Voice Over IP Protocol. It’s the technology that converts your voice into digital signals and sends them over the internet to the other person. Now that we have the technical definition out of the way, let’s try to go over this in layman’s terms.

A VoIP service is just a phone service delivered on the internet. The only difference is that internet is transmission medium that transfers the data instead of the old phone cable system.

Your voice data is converted into signals, which are binary, 0 and 1, and then transferred over the internet protocols to the other user.

Popular VoIP providers:

  • Skype
  • Line
  • WhatsApp
  • Facetime
  • Duo
  • Viber
  • Hangouts

Advantage of VoIP

Calling over internet is cheaper as compared to the traditional phone system because you don’t have to pay every-time you call. You can just get a good internet connection and call people all you want.

Is VoIP secure?

Since internet is under surveillance continuously by the government. You might feel a little insecure using VoIP services.

Moreover, Ever since Edward Snowden revealed the surveillance secrets of NSA and GCHQ, it has become increasingly important for the internet users to use VoIP VPNs for safe communication.

The VPNs, with their strong encryption make sure your communication is safe and secure. They also ensure you are free from the spying eyes of cyber-criminals and online surveillance agencies.
