Has anyone ever received a PRI Enabler on a software cartridge? I am upgrading a MICS and adding PRI and when I opened the box expecting to see a PRI Enabler authorization code I found a NA-MICS Rls. 7.0 software cartridge with sticker on the back that says "Norstar PRI Enabler Key Refurb". I have no idea how this would work??? Any ideas?
