Occupying only a fraction of the rack space required by previous server generations, a single S6 server can host up to 224 Intercom stations – the simple addition of software licenses and a few mouse clicks is all you need to upgrade your S6. S6 comes fully equipped with the proven VirtuoSIS Operating System and is driven by powerful software that brings together all the benefits of Commend VirtuoSIS technology: high-level fail safety, crystal clear voice and video communication, easy maintenance/upgrading, and low costs. The S6 also conforms to our hallmark “Evergreen” policy to provide full compatibility with previous system generations.
