Google is coming up with a Voicemail service which is something users would love as it reduces the pain of so many numbers.
Now, if all Google Voice did was send phone calls to your cell phone, that would be great all by itself, but the amount of extra tools and features are truly amazing
When a voicemail is recorded, you can check it by going to the Google Voice website and logging in, or calling your Google number. You can even be notified by email, or text message.
