prt all your RLIs in 86 and know what each is for - local, LD, 011, etc. Note FRL of each. prt sets, is there a common NCOS? Maybe 1 setting for agents, another for Supervisors, IT, Facilites, etc. Prt NPA, NXX, SPN, not which RLI is referenced. prt CDP as well, I think that is what you are asking?? If you didn't build it, takes slight research.
