Six free voice chat apps

Skype

The all-new Skype 4.0 for Windows continues Skype's dominance as an easy-to-use application for making free long-distance calls from your computer. The latest version improves on Skype's video and audio call quality, especially for those with slower Internet connections. The all-new interface lets you view the application's components as one window or in two separate panes. Extras include games, conference calls for up to 24 recipients, file-sharing, and instant messaging. In addition, you'll be able to call landlines and mobile phones at competitive rates.
