Alerts that you missed a call or have a essage that alert you until you check th

[mitchqc]

Does the iphone have an alert that you can set so that if you don't have your phone with you when you receive a voicemail it will continue to make the alert sound until it is checked. I don't like to have to constantly check the phone when I have left the room or have the phone in my purse. I have had this on all other phones and this is a big missing for me.
