On March 11, 2009 Google launched its much anticipated new service, Google Voice. This service provides people with a number they choose that can act as a central hub for all the numbers the person has, all for free.
Inbound calls to this number are forwarded to all of the other phones a person may have, depending on the preferences they have set up. For instance, it can be set up so a call placed to the Google number is not routed to a home phone line during certain hours of the day, say in the evening during dinner.
