The following changes apply for IP Office R12.0:
Change of Linux Operating System
The version of Linux used by Linux-based IP Office servers has changed from CentOS to Rocky Linux.
The new Linux is supported on 64-bit servers only. For Unified Communications Module support see the notes below.
For existing Linux-based IP Office systems upgrading to IP Office R12.0, you must upgrade using the processes in Upgrading Linux-based IP Office Systems to R12.0.
UCM support in IP Office R12.0 and higher
The Unified Communications Module (UCM) cannot support the 64-bit Linux used for IP Office R12.0 and higher. Therefore, you cannot upgraded a UCM to run R12.0.x software. However, Avaya supports UCM modules running R11.1.3.2 software in IP Office R12.0 and higher systems with the following caveats:
If the existing Unified Communications Module is running pre-R11.1 software, you must upgrade it to R11.1.3.2 using the processes in the "Upgrading Linux-based IP Office Systems to R11.1" manual.
The IP Office system will output a UCM version mismatch alarm each time the IP Office is restarted. You can ignore this alarm.
There will be no future updates to the IP Office software components provided on the UCM modules.
There will be no any future updates for the CentOS operating system and no security CVE patches for UCM modules.
Display of Web Management Version
For Linux-based IP Office systems, the Control Unit details shown in IP Office Manager now include details for the web management service.
