   Title:   Authorization-to-Reach for Communication Handles: Separating Identifier Possession from Permission to Contact

Abstract:

   Many Internet and telephone communication systems treat possession of
   a routable identifier as sufficient to attempt contact.  A telephone
   number, SIP URI, messaging handle, relay address, or marketplace
   contact reference can therefore remain a reusable reachability path
   after the purpose of disclosure has ended.

   Existing IETF and industry mechanisms solve related but different
   problems.  STIR and SHAKEN authenticate or attest originating
   identity.  Virtual or masked numbers hide a persistent endpoint but
   commonly leave a substitute route active while the alias is valid.
   OAuth can express delegated API authorization.  Spam scoring and call
   screening classify or reject an attempt after some path already
   exists.

   This document describes an authorization-to-reach model.  A visible
   communication handle is not, by itself, permission to create a
   communication effect.  A request is held as a candidate until
   current, purpose-scoped, revocable, and optionally consumable
   authority is validated.  The document is informational.  It asks
   whether the IETF Applications and Real-Time area should define
   interoperable semantics or an encoding for that authority (for
   example a PASSporT claim, a SIP header or pre-INVITE check, or a
   reusable authorization object).

   This work is not a 3GPP radio, core-network, or IMT-2030 architecture
   proposal.  References to machine-scale or future-network traffic are
   motivational only.  The intended protocol home, if any, is IETF work
   on SIP, STIR, messaging, and Internet communication identifiers.
