Message Waiting Notification requests originate from attendant consoles, front-desk terminals, or PMS terminals. When a request is entered, PMS sends a message to Communication Manager to change the state of the Message Waiting lamp. If the lamp is activated by AUDIX, INTUITY Lodging, or LWC, the PMS cannot deactivate the lamp. PMS cannot turn LWC or AUDIC messages on or off; these are controlled by Communication Manager.

Assign a console permissions COS to any console or terminal as part of the System Wide Retrieval Stations to retrieve requests for another station. Assign a client room COS to the extensions for which Message Notification is to be made.
