With new features recently added to Google's Gmail, the application now has the ability to freely make calls to phones at United States and Canada. And while, feature-wise, it is well behind competitors like Skype, its integration in Gmail makes it a serious option.

Google Voice rate per minute $0.02 in china,so pity!!!!!

For years now I've been developing and testing both personal and business oriented VOIP systems. And by far the most popular to the majority of people are the software-based services like Skype.

But so far, I'm pretty happy with this new feature of Gmail, even though can't use it in china.
