Avaya controls the use and access to some Messaging features through licenses, which the customer must purchase, including the number of Messaging enabled mailboxes the customer wants to use.
Messaging uses Web License Manager (WebLM) as its standard licensing mechanism. Messaging features are tied to the WebLM server and any client of the server can acquire and use a licensed feature. Messaging requires a WebLM hosted license. Messaging uses an enterprise license that allows the same license to be shared with multiple Messaging systems within an organization, if desired. The number of seat licenses is shared between all the Messaging systems associated with the license.
The license file controls the number of user mailboxes. The license is created based upon the host ID of the WebLM server. The user count can only be changed through PLDS either by purchasing additional seats or by moving seats between licenses. If more than one Messaging system exists in an enterprise, then the licensing model should be planned before obtaining the required license through PLDS.
