I signed up with GrandCentral and have been testing it for a long while now and I like the service a lot. I have a new phone number now that will reach me at all of my existing phones; home, office, cell phone and Skype. The only number you will ever need to reach me is (619) 393-2298. Now you can reach me everywhere with a single number. And if I move, switch jobs, or buy a new phone...this GrandCentral number never changes. You can even use my new number as an email address (firstname.lastname@example.org). It doesn't get much simpler than that.
Another cool feature of this amazing free service is the Call Me! button that you will find in the left column of this page, near the top. Click the button twice, enter your phone number and name, click the small Call Me button again, your phone will start ringing, pick it up and I will be on the other end!
