I need some clarification please, we are upgrading a G3si V6 to CM2.2 not changing the platform and we are going to use an orange card for the upgrade. We have some boards that we are installing for announcements, maint. test and expansion inter face. I'm getting conflicting information saying that we need a blowback and some saying we do not. I tried to find something on the avaya support site but nothing clear on if we do or do not need one. Any help would be greatly appreciated.
