CME Corlist

COR = Class of Restriction is the CME take on Calling Search Space and Partitions (in Call Manager)

One major caveat is that you need to make sure the incoming "corlist" need to be a superset (larger number of members) of the corresponding outgoing "corlist"

ie. looking at the config below the outcome is;

• DN60 can NOT call DN70 (because incoming corlist of INTERNAL is not a superset of UNRESTRICTED)
• DN60 can NOT calloutside (because INTERNAL and EXTERNAL does not overlap)
• DN60 can call DN80 (because INTERNAL and no corlist = call allowed)
