■Disallowed List Assignment. Disallowed Lists should be used for the default COR. You should use Disallowed List 7, which prohibits a variety of calls often made by toll fraud abusers. Review and add to this list as needed. When a 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 codes.

Automatic Callback can be turned on or off for remote access calls. However, the remote access Automatic Callback setting does not apply to network calls that have been routed to another system using ARS or UDP routing. Callback features only work for lines and trunks on a local system. “Callback” on page 4 provides additional information.

Table 4–2 includes a summary of the options discussed above, along with recommended settings for network routing. You may need to set these options differently, according to your organization’s needs and the requirements of your own network.
