In such a connected world, you likely have more than one phone number. There's your cell phone and your landline. Then there's your work number. After a while, that can get confusing.
You've got to check several voicemail boxes. You need to give friends multiple numbers. There's also the issue of call forwarding.
Google Voice is Google's attempt at revolutionizing the telephone. Essentially, Google Voice wraps all your phone services into a single number.
You can easily set up call forwarding so others can reach you however you wish. And you can enable voicemail sharing. That way, all your messages are in a central location.
With the app, you can use Google Voice right from your smart phone. You'll get low-cost international calls. Other features include integrated text messaging, call screening and transcribed voicemails.
