—-COR (class of restriction) Call manager Express
COR is about setting up “accesslists” for phones. The COR list is applied inbound and outbound on the router. The way it works is that the COR is applied to the dialpeer on the phone as it is incomming and the COR is applied outbound on the dial peer. upon dialing, the router checked the incoming COr and says, yes or no you have the required COR values to access the outbound dial-peer COR. IF there is no COR applied inbound at the phone side then they have no restrictions at all!
1. Create your COR names. That are used for access
