I just used a site called InviteShare to get an invitation to Google’s GrandCentral service. The site enables you to ring up to six phones from one number that will never change (unless they have a carrier problem like they did a couple weeks ago). Switch phones in the middle of a call, ListenIn™ on a voicemail, record calls… So many features! And everything’s free while the service is in beta period. I’d recommend it already. It has a few shortcomings (such as numbers disappearing from the availability list while searching and no contact integration with anything, even Gmail), but these will probably go away in future versions.
