Calling Party Anti-Spoofing

In April 2016, the CPAS Landscape Team published the Calling Party Spoofing Mechanisms and Mitigation Techniques white paper. The document informs policymakers and others about the challenges posed by Caller ID spoofing and related robocalling and provides a comprehensive overview of the industry work being conducted to address this challenge. This analysis concludes that a layered approach, similar to that used in cybersecurity efforts, provides the flexibility to respond to these evolving threats, and that mandating a single "solution" to Caller ID spoofing would be counterproductive. A wide range of mitigation techniques is proposed as the white paper specifically states that with a single mandated solution fraudulent callers would simply find other ways to exploit existing or future infrastructure.

This approach to Caller ID spoofing addresses the multi-faceted problem from all critical angles, calling on the expertise of multiple working groups and committees. ATIS' Next Generation Interconnection Interoperability Forum, its Packet Technologies and Systems Committee and the ATIS-SIP Forum Joint Task Force are all involved in this work. The CPAS Landscape Team is currently in abeyance, while potential next steps are determined.
