Google announced today that Google Voice is FREE to everyone. I have had an account for a long time and love it. It automatically can ring my cell phone or any phone that I choose and it automatically converts voice mail to emails and sends it to you. It really is the perfect service for people on the go.
What is also cool is you can set it up so it asks the person their name before it calls you and then you know and have the choice of accepting the call or not. I also use it to call people from my cell phone or computer with a headset and it works..very simple..
