Google has launched (not yet in India) a Gmail-integrated VoIP (voice over Internet Protocol) client that would allow users to make phone calls directly from the browser.
The feature is different from the voice and video chat that is already available from Gmail using the chat feature, in that it isn't solely between chat users. Instead, the new feature allow users to call any type of phone directly from their Web browser.
For those users seeing the test of the new product, the ability to make phone calls is added directly to the Google Talk popup that appears in the lower right corner of the Gmail screen, offering a keypad, a call history, and a credit balance. According to the screenshots from CNET, Google will offer free calls within the U.S. and Canada, with cheap international calling, in 2010.
If you are a Gmail user in the U.S., you can now make free Web-based phone calls to any phone in the U.S. and Canada right from the Gmail interface. You can also make International calls for fees starting at $0.02 per minute.
