Google Voice Features
https://www.google.com/voice/about
Here are some of the cool new features of Google Voice that I think are useful:
- Voicemail transcripts -- Read what your voice mail. This may come in handy if you're in a meeting or with your family, the W, or GF and can't pickup your voice mail.
- Share voicemail -- Forward your voicemail messages.
- Listen in - Listen before taking a call.
- SMS - Send, receive and store SMS messages.
- Place calls -- Call U.S. numbers for free.
- Forwarding phones -- Add phones and decide which will wring and in what order.
- Conference Calling -- Join people with a single call.
- GOOG-411 -- Check directory assistance.
