The Allowed-Denied Number Logic makes use of two Number lists:
• Allowed Numbers List: This is the list of numbers that can be dialed out from the BRI Port.
• Denied Numbers List: This list contains the numbers that are to be restricted from being dialed out from
the BRI Port.
When Allowed-Denied Logic is enabled on a source port, for each number dialed from the port, SARVAM UMG
uses the best-match-found logic to compare the dialed number with the Allowed Number list and the Denied
Number list.
The number is allowed to be dialed, if it:
• matches with both lists.
• matches with Allowed Number list, but not with the Denied Number list.
• matches with neither the Allowed List nor the Denied List.
The number is denied, if it matches with the Denied Number list, but not with the Allowed Number list.
The system does not apply the Allowed-Denied Logic:
• When dialed number string matches with any Access Code.
• When dialed number string matches with any Emergency Number.
To apply Allowed - Denied Logic on the BRI Port,
• Select the Allowed - Denied Logic check box.
• In the Allowed Number List, select the list number you have configured with numbers you want to
allow to be dialed out from the BRI Port. Default: 01
If you have not configured the Allowed Number List,
• Click Settings
