If you've been watching closely today you saw that Google acquired GrandCentral.com. This site allows to get a phone number and then have that number routed to any number of other phone numbers you want such as cell, work, or home depending on rules you define. It has a host of other features as well such as recording the conversation and sending individuals you're trying to dodge directly to voicemail. I came across GrandCentral a few months ago and have been tempted to try it out, but I haven't had a chance to. If you're using it, let me know what you think about it.
