Hi All,
ATIS just published ATIS-1000097.v002, Alternatives for Call Authentication for Non-IP Traffic.
The SHAKEN framework enables a SHAKEN-authorized VoIP Service Provider to deliver a cryptographically protected assertion that the calling user is authorized to use the calling telephone number to a called user via SIP signaling. This Technical Report considers scenarios where SIP connectivity is not available end-to-end (i.e., "non-IP" scenarios) and identifies and assesses potential approaches to determine and convey that the calling user is authorized to use the calling telephone number.
