Google is starting to roll out a new service based on “Grand Central,” a multi-phone/voicemail management business they recently acquired, with some very interesting features: Here comes Google Voice.

As you may know, GrandCentral offers many great features, including a single number to ring your home, work, and mobile phones, a central voicemail inbox that you could access on the web, and the ability to screen calls by listening in live as callers leave a voicemail. You’ll find these features, and more, in the Google Voice preview. Check out the features page for videos and more information on how these features work.
