Currently, video VoIP services like Skype and Viber are all using different video formats, requiring users to make sure they've got the same software before they start trading account information. Regardless, the ultimate aim of the project is to create a simple and unified service for Internet users to make easy video VoIP calls with.

The project is still very much in its early stages, and is currently only being tested through Firefox's nightly build feature, which allows users to download unstable and experimental versions of the browser to sample and provide feedback on.


At minimum you’ll be able to talk with other Skype users across the world and as more VOIP exchanges appear, this will slowly generate new free ways to make calls.WebRTC is already hailed as an easily accessible video client thanks to the fact that it works independently of any third-party software, but having an easily accessible WebRTC client pre-installed into one of the most popular browsers on the Web could be the shot in the arm that both VoIP and WebRTC needed to be catapulted into the mainstream. Keep in mind that VOIP is so young that you’ll need to look carefully at the costs and its limitations. It can still work cheaper because the connection usual occurs at the local exchange, so you can make long distance calls at the lower local rates. In some cases there is a charge when talking on normal phone handsets – this is because they need to plug into the local telephone exchange at some point. If you have a generous download limit from your ISP it means that calls to anywhere in the world will generally be free. VOIP uses your existing internet connection to send and receive the calls.

From version 3.0, Skype improves audio quality, features video calls and has a connect with the world option on Skype Public Chats. VOIP lets you talk to other users over the Web and, depending on your phone system and number dialled, allows computers to call normal telephones. All you need is special software that allows you to use VOIP (for those that love geeky terms, this stands for Voice Over Internet Protocol). Using your current Internet connection it is possible to make free Internet phones calls.
