Who is your carrier? If you're trying to access your voicemail to record a new greeting, with most you can call 123 send and it will go into your voice mail. If that doesn't work dial your own # from your phone. When the automated message comes on interrupt it by hitting #. It should walk you through the set up. If that doesn't work, you will have to call your carrier and have them reset it from their end. Hope this helps.
