might dial the 617 area code preceded by a 1. If the call would be routed as
a local call on your local system, the digits

here is the opposite of the FRL value assigned to an ARS route, where a
value of 0 is the least restrictive, and a value of 6 is the most restrictive.
The factory setting is 3. To restrict calls from using selected UDP or ARS
routes, assign a value that is lower than the FRL assigned to the route.
Network call routes (UDP or ARS) use this default COR FRL and do not
use barrier codes. As long as you require barrier codes for the default
COR setting, the barrier code FRL and not the default COR FRL, is
applied to remote access calls that arrive on PSTN dial-plan routed PRI
facilities or on DID trunks or that are made by dialing a Remote Access
code included in the non-local dial plan.

Disallowed List is assigned, ARS calls cannot reach the specific
numbers included on the list. When barrier codes are required for the
default COR, Disallowed Lists should be assigned to individual barrier
