When reviewing messages using the phone, you can change the order in which you hear messages. By default, messages are played starting with the newest message. You can set the Message playback order independently for unread, read, and saved messages.
For unread messages, read messages and saved messages:
Select Play newest first to hear messages starting with the newest message first.
Select Play oldest first to hear messages starting with the oldest message first.
Select Play important messages before others is selected to hear urgent messages first.
