Most Avaya telephones include a message waiting lamp, typically at the top right of the phone. This lamp lights when your mailbox contains any new messages that you have not heard. In addition, many Avaya phones have a Message button which also lights when your mailbox contains new messages.

Your system administrator can also configure your message indicators to light when a group mailbox contains new messages. You can then see and access that additional mailbox through Visual Voice. You can also access it by using the group extension number during mailbox login instead of your extension number.
