Google has confirmed the acquisition of Telephone Management Company Grand Central. TechCrunch is expecting the deal is done on approx $50 million range. Google will be moving the service over to Google’s network. A limited number of invitations for GrandCentral beta accounts will still be available. If you have a U.S. telephone number, you can sign up for an invitation at www.grandcentral.com.

What is GrandCentral?

GrandCentral is an innovative service that lets users integrate all of their existing phone numbers and voice mailboxes into one account, which can be accessed from the web. If you have multiple phone numbers(e.g home, work, mobile), you get one phone number that you can set to ring all, some, or none of your phones, based on who’s calling. This way, your phone number is tied to you, and not your location or job.
