Call Authentication for Non-IP Networks – TRACED Act Compliance


This webinar is now available for on-demand viewing.

You can also download a copy of the presentation slides.

Developed jointly by ATIS and the SIP Forum, SHAKEN defines a mechanism to verify the calling number and specifies how it will be transported across IP-based (i.e., SIP) communications networks. The TRACED Act and the FCC’s proposed implementing rules highlight a need to also examine non-IP (i.e., TDM) call authentication. Leveraging its extensive expertise in call authentication and TDM, ATIS launched a new Non-IP Call Authentication Task Force for TDM-based Service Providers.

The Task Force will identify and document call authentication challenges facing TDM networks, investigate the feasibility of new solutions in this area, and evaluate the implementation viability of TDM call authentication frameworks. This webinar provides insight into how the Task Force was formed, the value it brings to TDM-based service providers, and how this work relates to STIR/SHAKEN. An overview of the Task Force’s work program will be provided, along with the opportunity to ask live questions.
