What is Voice and how is it better than say, Skype? If perhaps a demonstration is required, feel free to shoot me a private message to get me in on this.
Look it up on the Google Voice website. There are two versions. One of them simply replaces your cell phone’s voicemail with Google voicemail emailed to you and texted to your phone. The other version gives you a new phone number, which you can have rung through to any or all of your phones at the same time. If you don’t answer it, this also then goes to google’s voicemail which is sent to your email and texted to your phone. I use this version so I don’t have to give out my home phone number to crazy clients, and so I don’t have to give out 2 different phone numbers to people so I don’t miss their calls.
I also have some invitations left if anyone needs it; send me a PM.
What does it do? I use it almost exclusively as a free SMS service, thought it’s also useful as a call screening interface and the ability to make/place calls from your computer (and headset).
