You can leave voice mails for someone else using the SIP-T28P IP phone. You can also
listen to voice mails that are stored in a voice mailbox. When receiving a new voice mail,
the phone will play a warning tone and the MESSAGE key LED will illuminate. The LCD
screen will prompt that the phone receives a new message and display a flashing icon.
If the voice mail pop-up message box disappears, it won't pop up again unless the user
receives a new voice mail or the user re-registers the account that has unread voice
mail(s).
