Class of Service/Restriction
Each extension and trunk has a COS (Class of Service) and a COR (Class
of Restriction) that defines what the user of that extension or trunk can or
cannot do. The system can have up to 50 of each, although most
companies use only a few.
To help you answer questions from users who may be having problems
with the system, you may want to record a brief description of the most
common COSs and CORs. For example, COS 1 might mean, “Allows only
local calls,” and COR 10 might be, “No long distance calls after 6 PM.”
Your communications department can give you the required details.
