Calling Privileges
Calling privileges define the destination a user is allowed to dial.
Primarily implemented on Cisco IOS gateways using class ofrestriction (COR).
Dependant on proper call routing. Higher granularity required for dial peers when deploying COR.

Understanding COR on Cisco IOSGateways
Calling privileges are implemented using COR.
COR lists contain CORs and are used to control call routing.
COR lists are assigned to dial peers:
Incoming COR list Outgoing COR list
For each call, the incoming COR list is matched against theoutgoing COR list:
If the outgoing COR list is a subset of the incoming COR list,the call is routed.
If no incoming COR list is configured, the call is always routed.

Cisco Unified Communications Manager Express and CiscoUnified SRST use the standard Cisco IOS COR concept.
Can be configured for inbound and outbound direction:
Inbound: Restrict destinations to which a user can dial
Outbound: Restrict who can call a user
For Cisco Unified Communications Manager Express, COR listsare assigned to ephones.
For Cisco Unified SRST, COR lists are assigned to number
ranges.

Configuring COR for Cisco UnifiedCommunications Manager Express
When using a standalone gateway:
2. Define COR labels.
3. Configure COR lists.
4. Configure dial peers and assign COR lists.
When using Cisco Unified Communications ManagerExpress:
1. Assign COR lists to ephone-dn.

Summary
Calling privileges are used within a dial plan to define thedestination a user is allowed to call.
Calling privileges are implemented on Cisco IOS gateways usingclass of restrictions (COR).
For Cisco Unified Communications Manager Express, the CORlist is directly assigned to the appropriate ephone; to assign aCOR list in Cisco Unified SRST mode, a COR list is matched to arange of directory numbers in global Cisco Unified SRSTconfiguration mode.
Configuring COR includes configuring named CORs and COR
lists, and assigning COR lists to dial peers, ephones, or CiscoUnified SRST.
