GrandCentral is a service I’ve blogged about before. It was a web-based service that assigned you a single phone number, and allowed it to be forwarded to other numbers. Calls could be routed based on caller, and the service had other great features like visual voicemail.
Google purchased the developer a few years back, and the service seemed to stagnate. Today, however, Google announced Google Voice, based on the GrandCentral service. In addition to the original features, Google Voice now has voicemail transcriptions, SMS support, conference calling, and support for international phone numbers. I’m looking forward to trying this out when it goes live.
