Technical Summary

   Secure Telephone Identity Revisited (STIR) provides a means of
   attesting the identity of a telephone caller via a signed token in
   order to prevent impersonation of a calling party number, which is a
   key enabler for illegal robocalling.  Similar impersonation is
   sometimes leveraged by bad actors in the text and multimedia
   messaging space.  This document explores the applicability of STIR's
   Personal Assertion Token (PASSporT) and certificate issuance
   framework to text and multimedia messaging use cases, including
   support both for messages carried as a payload in SIP requests and
   for messages sent in sessions negotiated by SIP.

Working Group Summary

   The consensus represented discussion among a fairly small group. The
   consensus among the group was strong, and no one raised material objections
   to the work.

Document Quality

   The shepherd is not aware of existing implementations. There have been
   statements that the work is needed by the emergency services community.
   Otherwise, like much of the work of STIR, implementation depends upon the
   work being used by other fora that define messaging systems and
   inter-carrier interoperability, such as the 3GPP, the GSMA, or ATIS.
