Peter,
the initial rollout of S/S does not include delegated
certificates. It's being rushed so at least basic call
blocking/tracing can be done by tier one carriers. It is usable in
the limited design but doesn't cover all use cases. Using the
public CA is still the work in progress from my understanding.
Delegated certs is a much more complex call flow and has potential
holes in the vetting process of the call flow chain. It has to
allow for a customer to pass the call through several App/CPAAS
providers before hitting the telco operators so the number of
companies that need to be properly vetted for ownership and right
to use information is MUCH larger.
I think eventually it will be effective in cutting down the number
of rogue callers and catching the ones that are egregious
offenders.

This one of the things being worked out. There are frameworks
for
certificate delegation and TN authorization, but I can't speak
to the
details.
Awesome to hear Calvin. I was under the impression that the
STIR/SHAKEN
standard had been ratified by the participating carriers and they
were
moving forward. I have not seen anything about cert delecation
and TN
authorization in the technical specs.
Is STIR/SHAKEN not really completed and ready for deployment yet?
The FCC
and larger carriers seem to be moving forward with test
implementations
without of TN authorization and delegation.
