Just a suggestion — if you are using Google Voice as your primary service then put your full 11-digit Google Voice number in one of the speed dial slots. That way, when you hit that speed dial code followed by the # key you'll go right into your Google Voice voicemail box.
Great Idea, but it didn't work for me. I tried 11 digit, 10 digit and 7 digit. I got message 'we could not complete you call. Any ideas?
