With Over a Million Users, Google Voice Opens To All!

When Google launches new services, they often gets a lot of hype (see: Wave, Buzz). Unfortunately, they don’t always live up to that hype (see: Wave, Buzz). But one service that Google launched last year definitely has: Google Voice. Sadly, it has only been open to those with invites. But starting today, it is open to all.

Google Voice started as GrandCentral, a startup launched in 2006 to revolutionize phone management on the web. Google quickly snapped it up in 2007 for over $50 million. For the next two years, it went through a metamorphosis. During that time, some wondered if it was yet another service that Google bought and let die. But in 2009, it emerged as the Google Voice butterfly.

The “early preview” of Google Voice that Google unveiled last year has since undergone a number of changes. Notably, SMS now works better, a Chrome extension makes it simple to keep on top of everything, and there’s a great mobile web app. Most importantly though, Google Voice now works seamlessly with all Android-based mobile phones. The solution is brilliant — and was the central figure in Google’s falling out with Apple (after they rejected the native Google Voice app).

There are also some features we’re still waiting for — such as full number portability and a desktop app (which may be scrapped now).

Google says that there are now over one million people actively using the service. You can expect that number to balloon now that anyone can go to the site and sign up.

In fact, why are you still reading this? Go sign up (well, if you’re in the U.S. –  yes, it’s still U.S.-only). After all, according to this chart, Google Voice is the pinnacle of human communication.

If you are not familiar with Google Voice, here are some of my favorite features:

• transcribed voicemails: whenever somebody leaves a voicemail, Google Voice will transcribe the message as best it can (this only works for English right now). These transcripts are then forwarded to your email account and you can also opt to receive an SMS notification.
• listening in to voicemails: whenever you receive a call and decide to let it go to voicemail, you can also choose to listen in and even pick up the call if it turns out to be an important message. This feels just like the old days when answering machines with tapes were still a novelty.
• call screening: one neat option in Google Voice is the ability to screen calls. If you activate this feature, callers will be prompted to leave their name once they call, and once you pick up the phone, Google Voice will play the name back and you can choose whether you want the call to go to voicemail or actually speak to this person. You can opt to let all unknown callers who are not in your Google address book go through this procedure or just those calls from callers who have blocked their caller ID.
• recording calls: at any time during a call, you can press 4 and the call will be recorded. This only works for calls you receive on your phone for now, and doesn’t work for outgoing calls.
• conference calls: just ask participants to call your Google Voice number and as more callers arrive, you can just conference them in – this works for up to 4 callers.
• switching phones: if you want to switch phones during a call (say you took a call on your landline and decide you want to take a walk and continue the call on your cell), just press * and all your other phones will ring again and you can continue the conversation on any othe rphone.
• SMS: you can send and receive text messages from your Google Voice account and web interface
• integration with Google Contacts
• it just works: the call quality is good, we didn’t experience any outages during the last few months, and calls aren’t dropped. Google Voice does what it says it does, and it does it well.
