I have been using Google Voice for a couple years now (from when it was Grand Central). It is great. Now it is openly available
The messages "transcribed" and sent to your email is nice (though it is still fairly lame). The ability to force unknown numbers to announce themselves before being put through to your phone is awesome. No more spam calls at all. You can also send calls to any of your phones based on show is calling. Basically it is great and it is free. There are lots of features I don't even use but the best features for me are call screening and emails with the voice messages. I don't have to worry about giving my phone number to business that will then abuse the information they were provided -
Google Voice gives me control over who can ring my phone and who must first leave a message.
