Hi, All,
Where is the truth about supporting CM5.2.1?

https://support.avaya.com/public/index?page=content&id=FAQ107065&group=UG_PUBLIC

Your call server must have Avaya Aura Communication Manager Release 6.2 or later version installed.

Avaya B189 Conference IP phones are supported on Avaya Aura® Communication Manager 5.2.1 and later

I confirm they work in CM 4.0. I'm not sure what exactly makes them uncompatable. They do need to be able to pull the latest firmware that is very important to resolve an overly sensitive touch screen issue.

When Avaya releases new firmware for a phone, they only test it against recent versions of CM and that is the list which is officially supported with that firmware. It MAY work on older versions of CM.
