The pitch is simple: one phone number for life. GrandCentral isn't the first with that pitch, of course. AT&T used to sell 700 numbers with the same promise, but that service was little more than glorified call forwarding. GrandCentral uses VoIP plumbing to do something more: have any or all of your phone numbers ring when you get a call, and consolidate your voice mail using a handy Web interface. It's slick, it's easy, it's powerful and it's one of the best applications of VoIP we've seen yet.
