So we'll all be sad not to meet in Vancouver this time, but given that we're scheduling a virtual meeting, I did want to give a pointer to a new draft:

https://tools.ietf.org/html/draft-peterson-stir-servprovider-oob-00

This draft works toward a more concrete protocol implementation of out-of-band STIR, for the case where a service provider (could be a carrier, large enterprise, or an OTT service) advertises a CPS that collects PASSporTs for calls that would terminate on its network. Because it is tightly coupled to the terminating side of the call, this flavor of CPS has a different security posture than a public CPS that is necessarily decoupled from call signaling entirely.

I know there is some talk out there about "OOB SHAKEN" these days, and to be clear, this is not an "OOB SHAKEN" draft - this looks at general tools that might ultimately support efforts to deliver SHAKEN out-of-band, but it does not limit its consideration of the problem space to the way that SHAKEN currently handles certification and signing. The plan is to deliver a mechanism that is applicable to a variety of potential policies in that regard.

If folks here are interested in working on this, let's discuss it a bit, and maybe find some agenda time for it.
