You have to be cleared to get aboard this new venture, just as we all waited for a G-mail addy, but it's not a long wait. I got mine in a week and a half.
GoogleVoice provides you with a new phone number that interracts with any and all of your current or future phone numbers and provides amazing service. Answers your calls, records messages, keeps a written transcript from all your phone numbers and a lot more.
The least it can do for me is to eliminate the monthly cost of AT&T's CallNotes.
Inside-the-US calls are free and there are steep discounts on international calls, as Google faces off Skype.
My GoogleVoice number is 314-292-9338. It rings home, office and cell phones and catches me wherever I am. Call me. Yes, I do answer calls, unless I'm asleep. Leave a message. I'll read it later.
