I am working on installing 200 icp in motel. It only has 1 console and everything else is guest rooms. I am a little confused on the cor groups and members. I have all my digit strings built and working with local and long distance built correctly. My question is in a motel environment where person at console toggles rooms for loca and long distance calls is cor even needed? I don't know what takes precedence cor or guest room being set for ld. Right now I have no cor built and everything seems to work correctly when toggling between local and long distance. I hope I explained this well.
