The Voice service allows users to make cheap long-distance calls online, and the ability to forward phone calls from one number to multiple phones.
Google says the new version is a "Web app" that is "much more interactive than the previous browser-based version of the service, with the ability to listen to voice mails directly from within the browser and to dial phone numbers on an interactive on-screen keypad."
The new version will work for iPhone 3.0 and above firmware and for WebOS based Palm smartphones.
