Skype is a VoIP application which allows you to use the Internet to call other users using Skype or on mobiles or land lines using credit purchased with a credit card. You can download Skype from its official website and create an account from the same place.
The application has a built-in friend finder you can use to search for other people. The computer where Skype is installed needs to have an active Internet connection as well as a connected and working microphone.
