We need to make a decision on what to reference for the emergency stuff.  I currently references my explanatory draft.  We discussed in the meeting on the rcd topic the proper separation of the stir mechanism that defines the PASSporT and the SIP mechanism that shows how it’s used.  I will definitely create and push through a sip mechanism draft updating RFC6881 to cover how we use RPH and Priority.  But should I push the explanatory draft through to an RFC so we can reference it?  I’m thinking not.  If that’s what we decide, then the reference would be to the mechanism document.

The reference to urn:service:sos is RFC5031.

Section 3.2 “When using "EScallback" as the "rph" assertion value, the "orig" claim of the PASSporT MUST represent the emergency network telephone  number. “  No idea what “emergency network telephone number is”.  Maybe “the telephone number used by the emergency services for call back, or a country or region specific dial string”.  I believe that won’t conflict with any text on authority (i.e. who has authority for a dial string would be determined by the same authorities who handle telephone numbers in a country or region). 

Other than that, I’ve reviewed it and think it’s ready to go.
