Google Voice to allow users to make free long-distance calls from Blackberry and Android handsets by using voice-over-Internet (VoIP) that bypasses the voice-fee structure of the major carriers.
Previously, to place a call using Google Voice, you had to dial your own Google Voice number from your cell phone, but with its new mobile application, users can make calls and send SMS messages directly from the mobile phone. Google claims full integration with each phone’s contact lists, so dial can be made with Google Voice directl from your existing address book.
