[16:01:32] <Mary Barnes_web_586> Yes.  Everyone is tired.....
[16:01:51] <Mary Barnes_web_586> I've been up since 1:30 am.  Nomcom interview at 4am
[16:01:59] <Jon Peterson_web_305> heh
[16:02:16] <Jon Peterson_web_305> we can discuss charter with connected identity

[16:12:15] <Mary Barnes_web_586> Looks good to me.
[16:12:25] <Ben Campbell_web_467> +1
[16:12:29] <Chris Wendt_web_994> +1
[16:12:30] <Brian Rosen_web_989> +1
[16:12:34] <Cullen Jennings_web_902> +1
[16:12:56] <Eric Rescorla_web_787> +1
[16:14:06] <Robert Sparks_web_474> the room has said do this already more than once - good to check that the mood hasn't changed, but yeah, lets go
[16:14:41] <Norbert Angell_web_807> as long as it's not "required", I can see some Operators saying no thanks?
[16:15:27] <Norbert Angell_web_807> +1
[16:16:15] Chris Wendt_web_994 leaves the room
[16:16:32] Chris Wendt_web_915 joins the room
[16:17:17] <Jon Peterson_web_305> yeah the forcing function would be critical use cases from large enterprises who might be like "if you don't want to do it i'll find somebody who does"
[16:17:57] <Robert Sparks_web_474> I still owe that sipcore doc
[16:18:09] <Robert Sparks_web_474> I sent the text to the list already
[16:18:10] <Brian Rosen_web_989> yes, you so, said a sipcore chair
[16:18:23] <Mary Barnes_web_586> I like that.
[16:18:26] <Brian Rosen_web_989> "do"
[16:19:57] <Jon Peterson_web_305> adopt!
[16:20:06] <Brian Rosen_web_989> yes please, adopt
[16:21:57] <Brian Rosen_web_989> could we have an options thingy that wouldn't send it unless it was going to be handled appropriately?
[16:22:30] <Jack Rickard_web_921> I'm also pro adopting if that wasn't clear
[16:27:37] <Jon Peterson_web_305> cid url
[16:28:11] <Ben Campbell_web_467> yes, that :-)
[16:28:12] <Ted Hardie_web_667> The data URL scheme is self-referencing data:(the encoded data).  I don't think I'd recommend that.
[16:28:26] <Ben Campbell_web_467> @Ted: sorry, I meant "cid"
[16:30:19] Karen Staley_web_413 joins the room
[16:30:52] <Ted Hardie_web_667> Please, please don't do that.
[16:31:27] <Norbert Angell_web_807> SHOULD instead of MUST?
[16:31:42] <Ben Campbell_web_467> @jon: wfm
[16:32:05] <Ben Campbell_web_467> Or what Brian just said
[16:32:21] <Jon Peterson_web_305> if the existing implementations use cid for emergency services, i'm cool with including it now
[16:32:21] <Ted Hardie_web_667> If you specify those two and then say anything requires an update to the spec, I think you're in the right place.
[16:32:30] <Ted Hardie_web_667> sorry, anything else.
[16:32:32] <Ben Campbell_web_467> +1 Ted
[16:32:33] <Eric Rescorla_web_787> +1 to what Ted says
[16:32:34] <Jack Rickard_web_921> We have jcd for by value though right?
[16:32:39] <Norbert Angell_web_807> +1 Ted
[16:33:26] <Eric Rescorla_web_787> could we also say that whatever it is has to bind it securely?
[16:33:32] <Eric Rescorla_web_787> (perhaps it already does?)
[16:34:09] Roland Jesske_web_820 leaves the room
[16:35:06] Peter Koch_web_251 leaves the room
[16:36:08] <Jon Peterson_web_305> the issue is jcd is by-value in the passport, not reflected elsewhere in the SIP message... this may be a point of misalignment between the rcd draft and the sipcore callinfo draft
[16:37:07] Peter Koch_web_468 joins the room
[16:38:07] <Brian Rosen_web_989> hmmmm, if the URI is in a call info and rereferencing it gets you the value you want, then I think the call info with CID gets you the value you want
[16:38:25] <Brian Rosen_web_989> "dereferencing"
[16:39:19] <Ben Campbell_web_467> I think Alec said the bit attributed to me. (Or maybe I was parroting him)
[16:39:29] Ryan Cross_web_790 joins the room
[16:39:56] <Jon Peterson_web_305> yeah, i guess my point is that callinfo header isn't going to point to a PASSporT with a jcd in it - or at least we'd need a way to do that if we want this to interface with callinfo directly

[16:49:12] Murray Kucherawy_web_522 leaves the room
[16:50:28] <Ben Campbell_web_467> It's perfectly feasible to make strong statements about integrity verification without making it part of passport verification
[16:50:48] <Jon Peterson_web_305> actively cause harm sounds a little too strong
[16:50:59] <Jon Peterson_web_305> it's only harm if nobody checks it later
[16:51:16] Sean Turner_web_966 leaves the room
[16:51:20] Sean Turner_web_412 joins the room
[16:52:00] <Ted Hardie_web_667> @Jon so it causes harm in the face of negligence.  I hear the argument as negligence is so likely that we can presume harm.  Is that a fair restatement?
[16:54:14] <Jon Peterson_web_305> well chris's text makes it clear that the terminating entity that consumes it is responsible for full verification
[16:55:53] <Ben Campbell_web_467> It's becoming less speculative. The FCC is getting concerned about text spam
[16:57:08] <Ben Campbell_web_467> Yay, we can have the same discussion about message integrity verification as RCD integrity :-)
[16:57:26] Chi-Yuan Chen_web_914 leaves the room
[16:57:53] <Ben Campbell_web_467> Will connected ID be a normative dependency?

[17:00:03] Ted Hardie_web_667 leaves the room
[17:00:18] <Richard Barnes_web_851> MLS has X509Credential, so STIR certs should notch in pretty directly
[17:00:50] <Richard Barnes_web_851> might need a little more glue to state the number you intend to claim, though that could probably be done at the app layer (cf. HTTP Server vs. SNI)
[17:01:15] <Richard Barnes_web_851> (or rather HTTP Host vs. TLS cert)
[17:01:45] Jonathan Lennox_web_377 joins the room
[17:02:30] <Ben Campbell_web_467> Punting is cool
[17:02:41] Geng-Da Tsai_web_579 joins the room
[17:02:46] <Ben Campbell_web_467> MLS for free is even more cool
