Avaya OneCloud™ Subscription system is a collection of UC and CC applications (Single or Geo-redundant data centers) connected to one or more WebLM servers, depending on your deployment model, for licensing.

After you install and configure the Usage Metering Collector, you must add the WebLM server to your Avaya OneCloud™ Subscription system by using the Usage Metering Collector. After the Usage Metering Collector successfully registers to the WebLM server, Usage Metering automatically retrieves the subscription license for the subscribed applications from the Avaya back-office systems and installs it on the WebLM server.

Avaya OneCloud™ Subscription uses the subscription license to enable application entitlements and capacities.

A subscription license has an expiration period of 30 days. Usage Metering automatically refreshes the subscription license after every 20 days. If Usage Metering is unable to refresh the license after 20 days, it sends an alert. If the subscription license is not replaced within 30 days, then after 30 days, the applications run in a license error mode.

For more information, see Usage Metering Collector did not refresh the subscription license.

If you want to increase your fixed quantity subscription, you must place a change order request with Avaya. You need not perform any changes on the WebLM server for the subscription license.

If you add or remove an application from your Avaya OneCloud™ Subscription system, Usage Metering automatically updates the WebLM server with the new application request.

After a new application request is received, the WebLM server notifies the Usage Metering Collector for the license entitlement.

The Usage Metering Collector grants the subscription license entitlement if the Avaya OneCloud™ Subscription system status is in a good standing.

The following criteria determine in good standing status:

• Billing status is good (offer dependent).

• All on-premise Avaya UC and CC applications that are part of your Avaya OneCloud™ Subscription system order are configured in the Avaya OneCloud™ Subscription system in Usage Metering Collector, and usage data of the applications is collected.

• The on-premise applications that are added to the Avaya OneCloud™ Subscription system are of either the minimum version supported by Avaya OneCloud™ Subscription or of a later version.

If the status is not in good standing, Avaya can disable the service by not renewing the subscription license.
