We just bought our son a chocolate. He loves it but...he says he discovered today that he had 5 voice mails by dialing in. he says there was NO indicator on the screen that he had voicemails. He thought it was odd he didn't have any so dialed in for the heck of it and discovered 5 new messages. IS there an indicator that appears on the screen when you have voice mails? thanks for any help you can give me.
