COR Configuration on Cisco Call Manager Express

The class of restrictions (COR) functionality provides the ability to deny certain call attempts based on the

incoming and outgoing class of restrictions provisioned on the dial peers. This functionality provides flexibility

in network design, allows users to block calls (for example, international numbers), and applies different

restrictions to call attempts from different originators.

COR is used to specify which incoming dial peer can use which outgoing dial peer to make a call. Each dial

peer can be provisioned with an incoming and an outgoing COR list. The incoming COR list indicates the

capability of the dial peer to initiate certain classes of calls. The o utgoing COR list

indicates the capability required for an incoming dial peer to deliver a call via this outgoing dial peer. If the

capabilities of the incoming dial peer are not the same or a superset of the capabilities required by the

outgoing dial peer, the call cannot be completed using this outgoing dial peer.
