Google has eyes on Voice - Google Voice beta launched

On March 13, 2009 Google released a preview of Google Voice, an application that helps you better manage your voice communications. Google Voice will be available initially to existing users of GrandCentral, a service they acquired in July of 2007. The new application improves the way you use your phone. Google Voice offers a host of 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 also can get transcripts of your voicemail and archive and search all of the SMS text messages you send and receive. You can also use the service to make low-priced international calls and easily access Goog-411 directory assistance.
