STIR/SHAKEN standards for TDM networks
2021-11-19 · News
WASHINGTON, DC — ATIS announced a technical report and two standards addressing the challenges of call authentication for calls that traverse TDM networks. The technical report provides a framework to evaluate non-IP call authentication and discusses approaches to accommodate the limitations of call authentication for non-IP systems. While these standards do not cover all non-IP networks or all service scenarios, they are a critical step toward mitigating illegal robocalling for consumers whose calls travel over TDM networks.
