Hi, Is there any Avaya Index knowledgable people out there still? I have someone that has a CPU X software level 9.1 and I need to downgrade it to level 9.0 ( I think) or below ??? To take advantage of event streaming. I think Avaya stopped this after a certain level of software??? Is this at all possible? Or is it a case of the software licence key on the CPU is a problem? It also has integrated v/m licence / silent intrusion licence and an 8 channel server licence. Many thanks in advance.
