The Personal Assertion Token (PASSporT) is specified in RFC 8225 to
convey cryptographically signed information about the people involved
in personal communications. This document extends PASSporT to include
an indication that a call has been diverted from its original
destination to a new one. This information can greatly improve the
decisions made by verification services in call forwarding scenarios.
Also specified here is an encapsulation mechanism for nesting a
PASSporT within another PASSporT that assists relying parties in some
diversion scenarios.

This document updates RFC 8224.

This document is a product of the Secure Telephone Identity Revisited Working Group of the IETF.

This is now a Proposed Standard.
