[stir] Availability of SHAKEN

[Tony Rutkowski <[e-mail]>]

Despite multiple references to SHAKEN as
some kind of STIR magic dust to make it work, it
is not apparent that any materials are actually
available on SHAKEN.  Or are they?

The only document anywhere that seem to
provide a sneak-peek is Chris Wendt's overview
at SIPNOC2016.

There are also Rich's NICC London Nov 2016
slides where we are told that
> ·SHAKEN: A United States service provider profile for STIR will 
> provide implementation guidelines and specify options within the 
> protocol to ensure interoperability between all service providers. The 
> ATIS/SIP Forum IP-NNI Task Force will complete this profile framework 
> (SHAKEN). Additional enhancements to the profile will be developed in 
> 2017.
If that assertion is ambitious, the next one
takes one's breath away:
> •We are going to cryptographically sign the SIP/IMS Call Signaling for 
> every single call in the U.S. network.
> –Hopefully/Especially those coming from the International call gateways.

The slide deck wraps up with a great pitch for
ATIS and its eCNAM spec ATIS-1000067.2015
that we could see if we had an extra US$60
to take a look at.  Presumably more will be
available now that SA1 adopted the new WID
proposal at its last meeting.
