I have an IPO V2 R8.1 with a Combo Card, TCM8, 2 Analog cards, and 2 expansion modules for Norstar phones. I have added an IP Endpoint license, but it shows as invalid. The combo card is supposed to have 10 VCM channels on it, but I do not see anywhere in the system that it shows having 10 VCM channels. What am I missing here?
