VoipStunt

VoipStunt is a VoIP program that allows you to connect your computer with phones all over the world. It uses the internet to transmit the audio in the form of data, and it provides excellent sound quality. You can easily chat with your contacts by either connecting VoipStunt applications in a chat session or by calling them directly to their assigned phone numbers. The application allows you to call to several countries for free (Argentina, Austria, France, Puerto Rico, Norway and many more), and others with low rates.

The website of VoipStunt will allow you to make a free call as a trial to test the sound quality. Once VoipStunt is installed, it allows you to call your contacts (peer-to-peer calls) for free. The installation has a step by step wizard that makes the process very simple, allowing you to select your language and hardware configuration with ease.
