Personal Assertion Token Extension for Diverted Calls
RFC 8946, “Personal Assertion Token Extension for Diverted Calls”, is a Proposed Standard document published in February 2021 by J. Peterson. It updates RFC 8224. The canonical text is published by the RFC Editor.
Abstract
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.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
