The PASSporT format defines a token that can be carried by signaling protocols, including SIP, to cryptographically attest the identify of callers. Not all telephone calls use Internet signaling protocols, however, and some calls use them for only part of their signaling path. 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.
