29 Outgoing Number Restrictions
Allowed and barred numbers in the ACS Resources screen are provisioned on a per customer basis.
Each customer has one incoming and one outgoing list. Each of these lists must be classed as either “Allowed” or “Barred”.
-
Allowed numbers are allowed only if they occur in the list. If the list is empty then no numbers are allowed – everything is barred.
-
Barred numbers are barred only if they occur in the list. If the list is empty then no numbers are barred – everything is allowed.
Use with Call Filtering Node
While the primary use of the lists is to allow or bar, based on service number (incoming, or CLI (outgoing) they may in fact be used to compare against any type of number available in the Call Filtering feature node in the ACS Control Plan Editor.
The lists can be applied in control plans by selecting the service number profile or CLI profile in the Call Filtering node in the CPE. As mentioned earlier, these lists may be used to match against any type of number but are labeled “Incoming” and “Outgoing” for convenience.
Examples:
-
You have an INCOMING ALLOWED list containing the numbers 555-1234, 555-1235, and 555-1236. Calls to the service numbers 555-1234, 555-1235, and 555-1236 are allowed but calls to all other numbers are not allowed, so a call to 444-5555 would not be allowed.
-
You have an INCOMING BARRED list containing the same numbers. Calls to the service numbers listed will not be allowed; calls to all other service numbers are allowed.
-
You have an OUTGOING ALLOWED list containing the same numbers. An outgoing call to CLI 555-1234 would be allowed (as would 555-1235 and 555-1236). Outgoing calls to any other CLI would be be barred.
-
You have an OUTGOING BARRED list containing the same numbers. An outgoing call to CLI 555-1234 would be barred (as would 555-1234 and 555-1236). Outgoing calls to any other CLI would be allowed.
Use with Prefix Tree Branching Node
The Prefix Tree Branching node allows you to select incoming or outgoing list data and branch on whether the number is in that list or not. Used in conjunction with other nodes, such as Profile Branching, you can determine whether it is the barred or allowed list and branch accordingly.
