VoIP (Voice over Internet Protocol) is the voice and multimedia communication over the IP, i.e. the Internet. In the past, VoIP services were not free and you would have to pay for them just like you pay for standard landline. However, Skype became the first company to offer free VoIP calls to Skype users and started booming in this industry.
Being able to call for free to almost anyone in the world just with the help of an Internet connection is something everyone will consider. Fortunately, many companies realised the potential, and now there are tons of apps available that provide VoIP service for free or offer reasonable rates to call anyone in the world.
All these apps offer different features and calling rates to mobile and landline numbers. So, choosing the best app for this purpose can be a bit confusing. You need to understand what features you need, and if you are going to call mobile/Landline numbers, then you may also consider checking out the rates and packages.
We have created this list of best VoIP apps that offer unique features with enticing calling rates. Just make your pick according to your requirement.
We will start with the app that gave VoIP all the shine. Microsoft owned, Skype is one of the most feature rich VoIP services, available on almost all platforms. You can call to any Skype user for free, whether it is an audio call, video call or a group call.

Its large user base also makes it a good option for free calling to anyone.
