I have a Unity Server running unified messaging and at version 4.0(5). I'm looking at doing an upgrade to version 4.1(1). Are there any compatibility issues with running Callmanager 4.1(3); also, will the hardware need to be MCS, or are non-MCS installations supported with this software?
The Unity platforms list details the supported MCS and non-MCS server hardware for running Unity. Is there a reason you don't want to go to Unity 4.2 or 5.0? Both support CallManager 4.1(3), which is our current version.
