I just found this out it is kind of cool. You can type in a code and have your voice mail shut off and then type in a different code and have it put back on. It will not affect anything I called customer service and they said it was fine. Anyways here is the code to shut off *770 and to turn back on *77. I just use it when I dont want a thousand voice mails from work. Also CS told me it might not be avaiable in all areas.
