To configure Google Voice with your OBi, you will need to get a Google Voice number. If you do not have a Google voice number, it is easy to get and it's free! To get started, visit www.google.com/voice. You will also need a Google account to sign up for Google Voice. If you do not have a Google account, click the blue button. Once you have a Google account, you can sign-in and complete the Google Voice process.
