Extension CORs
3.03 Each extension may be defined as Toll-Allowed or as having
one of three CORs. Toll-Allowed indicates that no denial check-
ing will be done for an extension. A COR assignment will indicate that
denial checking will occur for trunk calls made from an extension. This
checking will be according to the Control Plan linked to the extension's
COR number within the Trunk Group. The linking of an extension's COR
(in a Trunk Group) with a Control Plan is shown in Figure 3-2, using
the following information:
Extension W may access Control Plan 1 through Trunk Group A.
Extension X may access Control Plan 1 through Trunk Group B.
l
Extension Y may access Control Plan 1 through Trunk Group B
and may access Plan 2 through Trunk C.
Extension 2 may access Control Plan 3 through Trunk Group C
and may access Control Plan 4 through Trunk Group D.
Trunk Group Definition
3.04 Trunk Group access is primarily controlled by an extension's
Class of Service. By restricting access to certain Trunk Groups,
an extension is inhibited from making some calls on a general basis.
. .
The four paths that may be used after an extension has accessed a
trunk, are: COR 1, COR 2, COR 3 and Toll-Allowed.. Each COR may be
linked to a specific Control Plan which will define the actual digits that
may or may not be allowed. The Control Plan can also specify Denial
