(Feel free to cut this introductory paragraph, however.) Please refer to https://www.ietf.org/iesg/statement/discuss-criteria.html for more information about DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-sipcore-callinfo-spam/ ---------------------------------------------------------------------- DISCUSS: ---------------------------------------------------------------------- Taking over Alissa's DICSUSS, as a reminder to check this when a new revision becomes available: > (1) It seems to me that there is a privacy consideration that is not discussed > in this document, namely the unwanted exposure of the call types to third > parties. If I'm receiving a lot of calls from the debt collection agency and > my UA displays that information in my call log for anyone who might have > access to my phone, or an eavesdropper can glean that information from > intercepting my SIP signaling, as a user I probably want to be able to tell my > SIP provider to disable this. Perhaps this capability to request that certain > Call-Info headers not be sent is captured generically in RFC 3261 (I don't > remember), in which case pointing that out here would be good. Or if not, I > think something needs to be said about the ability for callees to turn off the > transmission of these type labels. > > (2) I'm a little uncomfortable with this document being the definitive source > for call types for all phone systems everywhere, since presumably these types > have other uses in telephony beyond the use envisioned by this spec. Is there > another document that could be cited as the definitive source for these types?
