You folks helped me about a month ago with some advice on eliminating DN conflicts. It's working, but I'm running into a new problem. Basically, I'm freeing up all the 5xx DNs on my MICS in order to add a destination code that will pass any number in that range to another system over T1 tie lines. Changing the 5xx DNs to another range is working OK. However, I now seem to have conflicts with sets that appear to be in that range. When I look at the DN/Port in Mntc, the DN is gone. But I can still see a set with that number. When I dial the set, it's shown as "not in service". I know that there are no sets connected with these numbers. Unfortunately, these conflicting "sets" are right in the middle of the range I was going to use. Any clues on how to get rid of these "phantom" sets so I can add my destination code and get the whole range?
