I have 3 of the DIG ADPX30 Nortel interface units attached to my IP Office. When I attempt to upgrade I can't get all three to upgrade. Sometimes two of them go to 51 and sometimes only one, but I can't get all three to upgrade. We have upgraded multiple times before without this issue. However the Nortel interface units have been a little flaky at times. Any ideas?
One more thing can I go to 8.1 without a license upgrade of some sort?
