I'm in the process of ordering an additional server for clustering a Unity Connection 8.5 implementation. The server part number is the same as the one that the client already has MCS7825I5-K9-UCC2. My questions are about licensing:
1. Does it is necessary to buy an additional Unity Connection software (UNITYCN8-K9) with user licenses for this new server? The client does not need additional users.
2. Does it is necessary an additional license for this server in order to be configured as a cluster?
