The customer has 5330 sets.
I suppose the issue started when I was attempting to set the LIMs up active with an analog line key...with the limited access I have been given for programming (admin portal) there is no analog line key available to me and apparently the tech group couldn't find it either...that probably prompted their comment.
As far as connecting the LIM to the set for failover only, I don't see what the system has to do with that...that seems to be a local operation, between the set and the LIM, but maybe I'm wrong...
