Document: draft-ietf-stir-servprovider-oob-05 Reviewer: Joel Halpern Review Date: 2024-03-28 IETF LC End Date: 2024-03-31 IESG Telechat date: Not scheduled for a telechat Summary: This draft is probably ready for publication as a proposed standard Major issues: N/A Minor issues: There is one aspect of the CPS Advertisements that I was unable to follow. I presume this is clear to those participating in the work, but wonder if my confusion indicates potential for clarification. The draft contains a very clear description of the cotnent of the advertisements, and how those advertisements can be used to map from a phone call being placed to URI to submit the PassPort. However, I do not know how the placing party finds the advertisements themselves? Is there some assumption about a STIR related information repository that would provide these?
