Avaya OneCloud™ Subscription supports sharing of applications, such as Avaya Aura® Messaging or CMS, between the Avaya OneCloud™ Subscription systems that are configured on the same Usage Metering Collector. For example, if you have subscribed for two Avaya OneCloud™ Subscription systems, one for the call center and one for the back office, you can share the same CMS between the two Avaya OneCloud™ Subscription systems, provided these two systems are configured on the same Usage Metering Collector. Shared applications are not independently charged.
