I signed up for an account with Grand Central. It’s a limited beta, but they eventually had a slot for me.

Essentially, I give out my GrandCentral number, which rings in multiple locations. (Currently, my cell phone and my school desk phone.) But it treats calls more like e-mail: I can set up ‘rules’ on what calls get through and what calls don’t. There’s voicemail which I can listen to via the Web.

I have a few invites, if anyone is interested.
