Hello,

Chris Wendt and have a draft that has split off from our work toward delivering rich call data (RCD) in the STIR WG. This is for carrying data elements like a caller name, a jCard, call reason, and potentially related elements that will be rendered to the called party to help them decide if they should pick up the phone. We ultimately decided that, instead of doing a one-off for conveying RCD within the PASSporT object, we should instead focus on how that information is best relayed in baseline SIP, and keep the STIR part of the problem confined to signing over those fields as they appear in SIP requests.

So this draft is the core SIP part:

https://urldefense.com/v3/__https://tools.ietf.org/html/draft-wendt-sipcore-callinfo-rcd-03__;!!N14HnBHF!qN-QsYPq0MvWk7reTKb984Mry91INiEDfIoc4rQhKA_mMt9ysIG4-Yz2itA0$ 

We'd be interested in the thoughts of the SIPCORE WG about the fundamental approach here, and ultimately if there's interest in adopting this as a WG item here.

Thanks!
