What are the advantages of using TelePresence Server and a MCU in combination?
Each has some overlapping capability, but there are a few things that each can do individually that the other can't - so there may be circumstances where you would have both in your environment.
But keep in mind that both are End of Support products so you should probably consider migrating to something more current (like CMS or Webex).
