Free worldwide calling with Voixio

Voixio (www.voixio.com) is a flash based VOIP calling service. Voixio offers free international calls anywhere in the world with a special advertisements policy. The moment you hit the call button, an advertisement starts running in the Advertisement panel. Once the ad is over, the call is placed to the other party. When you go to Voixio, a screen will pop-up to enter your username/password, is where you log in by inputting your email address and password and clicking the login button and also given an option to register. Voixio will detect the webcams and microphones that are available on your computer and these will be displayed when you click the “Camera & Mic” button located under the main video window and to the right of the volume slider bar. You can make calls to Standard domestic and international, landline and mobile telephone numbers or other Voixio users or any SIP address. You can free conference calls between Voixio users. You can add callers to an existing conversation (or conference) by making a call to an additional user, thus inviting him/her to the conference. By this process I made free calls to Bangladesh, India, Sweden and lot of other European countries but call duration was less than 2 minutes. But all calls are free and that is the main crucial point. You can try this service.
