Had a trouble ticket for an older IP Office (r9.1) and was advised that due to the SD Card being corrupted and licenses sitting in ADI, we’d have to request temp licenses and upgrade the customer’s hardware and software. I said they were already a v2 and was told that the controller had to be at least a PCS21 in order to be compatible. I cant find any documentation from Avaya that specifies PCS requirements anywhere and the compatibility matrix doesn’t notate it either. Anyone know where I can find it?
