You can leave your email address with Google if you are interested in signing up for Google Voice which should be released to the general public in the next few weeks.
Google Voice will give you “one number for all your phones, voicemail that is easy as email and many enhanced calling features like call blocking and screening, voicemail transcripts, call conferencing, international calls, and more.”
The service is free and sounds very exciting. I’ll let you know all about it when I am able to sign up!
