When you log into your mailbox, messages are played to you in the order in which they were received. You can specify the order in which different types of incoming messages (voice, email and fax) are played. For example, you can choose to hear emails first or fax messages before voice messages.

Whichever order you specify, new messages are presented first followed by old or read messages. While you are listening to your messages, you can press *# to skip to the next type of message.
