Class of Restriction
You use Class of Restriction (COR) to define the types of calls your users can 
place and receive. Your system may have only a single COR, a COR with no 
restrictions, or as many CORs as necessary to effect the desired restrictions. 
You will see the COR field in many different places throughout the DEFINITY 
System - when administering phones, trunks, agent logins, and data modules, to 
name a few. You must enter a COR on these screens, although you control the 
level of restriction the COR provides. You must administer a COR for the 
following objects:
Agent LoginID
Access Endpoint
Announcements/Audio Sources
Attendant Console
Authorization Code — COR Mapping
Console-Parameters
Hunt Groups
Loudspeaker Paging
Data Modules
Remote Access (each barrier code has a COR)
Station
Terminating Extension Group
Trunk Groups
Vector Directory Number
Called-party and calling-party restrictions
Called-party and calling-party restrictions are the basis for all CORs. When no 
restrictions are needed, assign a single COR with called-party and calling-party 
restrictions set to none. You can use this COR for unrestricted telephones, trunk 
groups, terminating extension groups, Uniform Call Distribution (UCD) groups, 
Direct Department Calling (DDC) groups, data modules, attendant groups, and 
individual attendant extensions.
The called-party restriction is checked only at the called terminal, module, 
attendant console, zone, or group, even if a call redirects from one telephone to 
another. For example, if a called terminal (with no terminal restrictions) has Call 
Forwarding active to a restricted terminal, the call still completes.
