The latest version of the software (220.127.116.11) is available for downloading through the Avaya website. However, this version doesn't have an official release notes with the system compatibility and requirements. More over, based on the date released, it would be logic to think that compatibility doesn't actually exist since release year was 2012.
If you have an older version, download the latest one and apply it over the currently installed one. It might work this way.
