Join the Spoofing-Mitigation Working Group

There is currently a strong focus by regulators in North America on combating nuisance calls, including robocalling and illegitimate caller ID spoofing, using caller authentication techniques based on standards developed by ATIS and the IETF. While published standards address mechanisms for caller authentication in general, they do not specifically consider caller authentication in the context of 9-1-1 calls or callback calls. There are new standards development activities underway to address the application of caller ID spoofing mitigation techniques to 9-1-1 and callback calls. It is critical that public safety have input into these standards development activities to ensure that the operational needs of 9‑1‑1 authorities and PSAPs are supported by the standards that ultimately get generated.This working group will address topics including: 

• Identification of use cases associated with legitimate and illegitimate caller ID spoofing;
• Description of the information that should be displayed at the PSAP when verification of caller information passes/fails;
• Specification of the handling/treatment of calls where the caller information is suspected to be spoofed;
• Description of the role of analytics in the display and treatment of suspected spoofed calls;
• Considerations related to caller location spoofing reporting and mitigation; and
• Considerations related to the display of PSAP caller ID on callback calls (and in particular, the ability to allow the PSAP caller ID to remain "private").
