The release of Acme Packet ECZ730m1 software introduces the ACLI command fraud-protection. This allows the SBC to store multiple black lists, white lists, SIP redirect lists, and rate limit entries for fraud prevention and call control. Multiple lists may exist where entries are stored in separate XML files.

Lists (XML files) may be initially created through the command line (ACLI) or web interface. If the preference is to manage lists manually then once a list is created it will need to be downloaded and the XML file(s) edited with a text editor, similar to managing Local Route Tables (LRT). Otherwise, all entries may be added, modified, or deleted using the web interface.

Below is an example of the GUI configuration elements for managing fraud-protection


Below is an example of creating a new fraud-protection XML file in the ACLI called test.xml. The Whitelist section permits all calls based on the From header matching acmepacket.com through the realm called peer, as well as calls to based on the To header specific UK phone number on any realm (the * is a wildcard for all realms) . The Blacklist section rejects calls based on a variety of criteria. Note that even though calls are blocked to +44 based on the To header, calls to +441189240000 are permitted since this is a more specific match in the Whitelist.

The command show fraud-protection all will show fraud definitions and whether any matches exist. You can also use show-fraud-protection all matches-only and show-fraud-protection blacklist or show-fraud-protection blacklist matches-only

 

The command show fraud-protection stats show a summary version of matches

    Hi Mark,

    Do you know if this release is going to be available for the NN 3820? The release notes for the ECZ740 don’t include it.

    Thanks!

    Mark,

    Can you use the LRT to manipulate digits? Our carrier can deliver toll free numbers to our system as 00000-2XX-XXX-XXXX and we want to replace the 00000-2 with just 8. For example, toll free number 800-444-44444 would be delivered to us as 00000-200-444-4444, and we would change that to be just 800-444-4444. But we’d want to wildcard the conversion, we don’t want to enter and convert every inbound number, just remove the 00000-2 and replace it with 8.

    Thanks.

    Adam – you could do that easily with an HMR. Do a manipulate on your To header or Request-URI and use a regex pattern to search for the 00000-2(.*) and replace with 8+$headerrulename.$elementrule.$2 … or something to that effect. sip-manipulations are insanely powerful.

    can you please share to me how to do black list with oracle sbc 3820 software version 7.2
    thank you

    Does anyone have an example of a valid redirect value format? I’ve tried several without any success.

    Thanks in advance.

    I guess you can not send it to a URI, only another host, session agent or session group.
