Thanks to Russ for the notes. The bluesheet section is not yet complete - people were having problems with the etherpad. If you were present and haven't already let me know by email, please do so ASAP. ------ STIR - Interim meeting - 2020-04-20 Notes ----- Jon Peterson (Neustar) gave an update on the Out-of-Band document (draft-ietf-stir-oob) and the PASSporT Divert document (draft-ietf-stir-passport-divert). The Out-of-Band document is with the RFC Editor, and PASSporT Divert got some DISCUSS positions from the IESG that need to be resolved. The main concern is about “div-o” hiding the original called number by not including a “div” PASSporT. The “div-o” text needs to be fleshed out a bit more, which would require the document to come back to the STIR WG. The current thought it to explicitly state that “opt” is for “Original PASSporT”. Martin Dolly (AT&T) gave an update on the Assertion Values for a Resource Priority Header Claim in Support of Emergency Services Networks dcoument (draft-ietf-stir-rph-emergency-services). References are needed for “SOS” addressing, “anonymous”, and “Unregistered UE”. Expect that the document will be ready for WG Last Call in July. Jon Peterson (Neustar) talked about the Rich Call Data PASSporT extension document (draft-ietf-stir-passport-rcd). Major update was to include a “crn” claim that corresponds to a “reason” or string representing the intent for a call. This concept is also discussed in draft-wendt-sipcore-callinfo-rcd, which says “this message SHOULD be no longer than ten words.” String is the primary format, but an extensible format allows flexibility. Coordination with SIPCORE is needed before this document reaches WG Last Call. Eric Burger (Georgetown University) talked about an IANA registry for country-specific STIR Trust Anchors (draft-burger-stir-iana-cert). Concerns were expressed during IETF 101 that IANA would need to be an arbiter of who gets to put records in registry, but since then Burger realized that it does not matter. In real life, illegal robocall mitigation is all about reputation and statistics. We know there will be calls that have no attestation that are just fine, and we know there will be call that will have the highest levels of attestation that are illegal robocalls. STIR increases the confidence in the identifying the caller, which can be used to allow, warn, or block the call. Not expecting IANA to figure out who is the responsible organization, including delegation, for making or updating a registration. Rather, IANA would confirm valid cryptographic identities. Te re are not privacy concerns since the entries are associated with governments. The suggestion is a “First Come First Served” registry.
