Class of Restriction
(COR)
|
To prevent toll fraud, it is recommended that
you create a COR for voice ports that allows subscribers to call
only other numbers with the same COR. If you decide later that subscribers
need to call numbers with different CORs, add permissions for the
other CORs one at a time. The AMIS Analog Networking, Message Delivery,
and Outcalling features require the ability to call numbers with
different CORs.
