Specifying Redirect List

This Redirect List allows you to add custom entries to configure a redirect target for suspicious users. You can add Phone numbers, IP addresses, User names and SIP User Agents. You can also exempt users.

You can either upload the redirect information provided through the import menu or you can manually add the custom entries.

The Global flag is marked as True for entries uploaded through import menu such as the phone numbers/usernames, hostnames, and SIP User Agents which have been identified and verified to be involved in fraudulent activity.

You can Add, Edit, and Delete the users. Double-click a user to edit the details.

If you want to exempt a specific entry, select the User exempted from Redirect checkbox while adding or modifying a user entry. Exempted users are shown in a seperate list in the main Redirect List page. But the exemption will not work for other lists like Blocklist or Ratelimit. To exempt an entry from all lists, add the same in Allowlist.

Entry can also come in this list using Automatic Configuration: Subscribed flag is true for such entries and also those entries are not meant to be used for raising further incidents.

The Redirect List supports all the data types supported by SBC for processing the calls. The available data type are:

• from-hostname

• to-hostname

• from-phone-number

• to-phone-number

• from-username

• to-username

• user-agent-header

You can filter the data based on these data types. Click the required data type in the screen and data is displayed for the selected data type.
