Illegal robocalls continue to be a significant problem for consumers and businesses of all sizes. STIR/SHAKEN is expected to reduce illegal spam calls, but those behind the illegal calls will persist, wasting time, clogging up phone lines, and in some cases, perpetrating phishing attacks. Join us as we discuss the current state of STIR/SHAKEN and explain why further Robocall Mitigation is required. Stay with us as Gerry Christensen, VP of Business Development and Strategic Partnerships at YouMail joins us to share an AI-powered robocall analytics platform that can be used by service providers and enterprises to block much of the unwanted traffic.

8. STIR/SHAKEN
What it Does Do:
• Secures the Caller-ID information
• The originating operator attests as
to whether the caller has permission
to use the number
• Defines three levels of attestation
(A, B, C)
• Tell subscriber if the call has an
attestation (but not the level)
• Provides traceback
What it Does Not do:
8
• Pass the level of attestation to the
called party
• Monitor patterns of calling or abuse
• Know the intent of the caller
• Differentiate between legitimate and
fraudulent behavior
• Redirect suspicious traffic
• Terminate known fraudulent calls
