I want to use Google Voice strictly as a new phone number (so I can have a local number without changing my old number I have had for years). However, I don't want my voicemail being changed, I want to simply leave it as Verizon voicemail. I signed up for a new number and it seems to be forwarding right. But now somebody just called my old number and got a Google Voicemail message. How do I change that so that it will be my Verizon message? I went into settings and it still shows "My carrier" as the voicemail setting. I'm confused.
