Software Upgrade
This section explains how to upgrade your device, including the CU360 App and the companion
web server app. Those apps and the preinstalled software and OS are upgraded using a software
package (auto-extracting .exe file)
Since first release, CU360 software packages are signed by an Avaya Certificate Root Authority
recognized by the codec unit.
Only verified signed software packages will be accepted by the codec unit.
A software package will be installed only if the codec unit verifies that:
• The software package is signed by Avaya IT Root Authority and produced by an
authorized build server.
• The software package content is not tampered or changed in any way.
By default, an unsigned software package is not accepted.
Important
• You can force the system to accept an unsigned package by setting “Verify Signature”
to No. Unsigned packages can be provided by Customer Support only for specific
purposes and should not be used otherwise.
