Foonz is a new free service in beta that allows you to make free conference and group calls. Sign up and Foonz gives you a free personal phone number. Dial your Foonz number, select the friends you want to call and Foonz alerts them either via im or text message. While you’re waiting for your friends or co-workers to join the conference call, you can listen to music, play games or chat in the Foonz arcade. And Foonz is totally free, except that you’re cell phone will bill you regularly for the minutes you used while talking.

So, if I understand this, you can talk several people, but only use the minutes for one call. And on nights and weekends, when minutes are free, using foonz would be completely free. This is cool.
