Which role do I install if I only want a server handling UM tasks? RRS feed

  • Question

  • One of our clients has a single Exchange 2013 server and we want to dedicate another server to UM.  The goal is to be able to sustain an outage (or reboot) of the main Exchange server and still have the auto-attendant answer and route calls.  Since there is no longer a UM role, which role should we install - Mailbox or CAS?  The most important key to this is that their phones continue to flow even when the main Exchange server is offline.  Thanks for you help!
