Specifying Ratelimit List

The Ratelimit allows you to add the custom entries. You can add Phone numbers, IP addresses, User names and SIP User Agents. You can also exempt users by removing them from the global ratelimit.

Customers may either upload the ratelimit information provided through the import menu or they can manually enter the custom entries.

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.

Use the Configuration menu to adjust the points awarded for prefix and exact match hits from this list.

Should you want to exempt a specific entry, check the corresponding flag while adding or modifying that entry. But that exemption does not work for other lists like blacklist or redirect. If you want to exempt an entry from all lists, add the same in Whitelist. The CPS or MAC entries are not taken into account for raising incidents from ratelimit list, only presence is checked.

Entry can also come in this list via Automatic Configuration: Subscribed flag would be true for such entries and also those entries cannot be used for raising further incidents.

The Ratelimit supports all the data types supported by SBC for processing the calls. Following are the available data types:

• 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.
