Mechanism for International Signature-based Handling of Asserted information using toKENs (SHAKEN)- ATIS-1000091

This document provides telephone service providers with a framework and guidance on how to use Secure
Telephone Identity (STI) technologies on IP-based service provider voice networks (also to be referred to as Voice
over Internet Protocol [VoIP] networks) in scenarios where a call originates in one country and terminates in a
different country. ATIS-1000087, Mechanism for Initial Cross-Border Signature-based Handling of Asserted
information using toKENs (SHAKEN), provides an initial mechanism for cross-border SHAKEN calls, but it
recognizes that it is only the first step, and that a more general approach is required to accommodate the general
cases of international SHAKEN calls. Published 2020-07-16.
