Yahoo announced today that its Yahoo Messenger with Voice service (formerly called Yahoo Messenger 7) is out of beta. PC-to-PC calls to other users of Yahoo's messaging service are free. The Phone Out feature lets users call traditional phones and mobile phones from their PCs for low per-minute rates--calls within the United States and more than 30 other countries can be made for less than 2 cents per minute. The Phone In feature allows users to receive calls on their PCs from traditional lines or cell phones. Users pay $2.90/month or $29.90/year for a traditional phone number, which can be based anywhere in France, the United Kingdom, or the States (additional country-based numbers will be added soon).
