The Personal Assertion Token (PASSporT) format defines a token that
can be carried by signaling protocols, including SIP, to
cryptographically attest the identity of callers. However, not all
telephone calls use Internet signaling protocols, and some calls use
them for only part of their signaling path, while some cannot
reliably deliver SIP header fields end-to-end. This document
describes use cases that require the delivery of PASSporT objects
outside of the signaling path, and defines architectures and
semantics to provide this functionality.

Group of the IETF.
