You can enable or disable the Message Waiting Indicator for users associated with a Unified Messaging (UM) mailbox policy. Message Waiting Indicator is a feature found in most legacy voice mail systems. In its most common form, it lights a lamp on a voice mail subscriber’s phone to indicate the presence of a new voice mail message. Message Waiting Indicator can also be a text message sent to a UM-enabled user's mobile phone. The default setting is enabled.

If this option is disabled on the UM IP gateway, this feature isn't available to UM-enabled users associated with the UM mailbox policy. This option isn't available to UM-enabled users who have a mailbox on a Microsoft Exchange Server 2007 server.
