Combating Spoofed Robocalls with Caller ID Authentication
"American consumers are sick and tired of unwanted robocalls, this consumer among them. Caller ID authentication will be a significant step towards ending the scourge of spoofed robocalls. It's time for carriers to implement robust caller ID authentication." – FCC Chairman Ajit Pai
And not only Americans are sick as this is a global phenomenon, annoying consumers all over the world. Other abuse cases happen in Europe where Carriers charge a fee on top of the termination rates for calls terminating in EU member countries but originating from outside of Europe. As one can imagine this practise is just ripe for fraud and faking European A numbers has become a real challenge.
Since we are heavily invested in analysing fraud al call anomalies in our SBC platforms, this type of fraud cannot so easily be verified as number database or HLR lookups would need to be performed to verify that these numbers are actually assigned to users.
What Does SHAKEN/STIR mean if not related to James Bond or Cocktails?
SHAKEN/STIR is a framework of interconnected standards. SHAKEN/STIR are acronyms for Signature-based Handling of Asserted Information Using toKENs (SHAKEN) and the Secure Telephone Identity Revisited (STIR) standards. This means that calls traveling through interconnected phone networks would have their caller ID "signed" as legitimate by originating carriers and validated by other carriers before reaching consumers. SHAKEN/STIR digitally validates the handoff of phone calls passing through the complex web of networks, allowing the phone company of the consumer receiving the call to verify that a call is from the person making it.
What is Cataleya doing?
We clearly support this function in our SBC's for our current and future US based customers but also believe that this is the most reliable practise to adopt around the world to protect consumers and stop abuse and fraud.
Our platform is already with ATIS Robocalling Testbed undergoing certification. The ATIS Robocalling Testbed, exclusively hosted by the Neustar Trust Lab, serves as the industry interoperability test facility to validate the effectiveness of caller authentication standards developed by the Internet Engineering Task Force (IETF) and ATIS. Specifically, ATIS developed “Signature-based Handling of Asserted information using toKENs” (SHAKEN) as an implementation framework for service providers to better combat robocalls and call spoofing on IP-based networks.
