STIR Interim Meeting 16 June 2017 1900 UTC, via WebEx Thanks to Eric Burger and Russ Housley for taking notes. Robert - Agenda Bashing ======================= No changes to the agenda were requested. Reminder that the NOTE WELL applies to this meeting. See https://www.ietf.org/about/note-well.html. Jon Peterson: Out of Band (draft-rescola-fallback-02) ===================================================== Discussion the processing of PASSporT by a Call Placement Service (CPS): Draft: CPS accepts a PASSporT with an ‘acceptable’ root Eric B.: Should just be a hint; whether a particular PASSporT is accepted or not is a matter of local policy EKR: Would the receiving CPS need to know about all other CPS? Mary: For the gateway use case, the gateway would probably have an account at the CPS. Jon: I would not want to require an account, as that would kill the possibility of having an open, public service. That said, would expect existing STIR credentials would already be trusted. I would not rule out pre-association, such as an account, from the gateway. Discussion on how to query the CPS to retrieve the PASSporT: EKR: Is this not a pen register? Robert: We probably need to assert both called and calling identities. Jon: Likely, but still have a problem with diversion, which we will talk about later. Also, there is potentially a problem because you are handing all the metadata to the CPS; conversely, someone can attack a CPS to extract metadata. Plan to address the former with encryption. Not sure there is a technical solution for the latter. Discussion on WG Adoption: Shockey: I will not work on the document. Robert: Will take call for adoption to the list. Martin Dolly: RPH extension (draft-singh-stir-rph-00) ===================================================== Martin discussed the recently posted Internet-Draft that proposes a PASSPorT Extension for Resource-Priority Authorization. There was a suggestion to reduce the complexity of the "rph" claim by eliminating one layer of nesting. Robert: Will take call for adoption to the list. Jon Peterson: CNAM (draft-peterson-stir-cnam-02) ================================================ Discussion the proposed addition of the "cna" claim to PASSporT, which is intended to be richer that Caller-ID: Shockey: A lot of people outside the IETF are working on this topic. Is this a generic object transport proposal or something interoperable? General discussion ensued over the fact that calling name delivery is outright illegal in many jurisdictions, including most of the European continent, so this topic really a North American issue. Robert: Will take call for adoption to the list with the understanding that draft-peterson-stir-cnam will be posted with a new filename that avoids the use of "cnam" to eliminate the potential for confusion with other activities that are taking place in other fora. Jon Peterson: Diversion (draft-peterson-passport-divert-01) =========================================================== Discussion of the handling of retargeted calls. Is a reason code needed to indicate that retargeting has taken place? Mary offered to send use cases to the list. Robert: Heard lots of interest to adopt this document. Will take call for adoption to the list. Other ===== Plan to discuss Connected ID at the upcoming IETF 99 meeting in Prague.
