I currently have a working Google Voice account working on my phone. I have added another account to the Google Voice app but when i try to log in with it i keep getting Not Subcribed. Your Google Account is not yet enabled for Google Voice. Visit www.google.com/voice to sign up. The account for that email address is already working for Google Voice and works fine on my PC but i can't login with the Voice app on the phone. I added that email to the Accounts & Sync on the phone but that didn't help. What am i missing ?
