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.<br>
<br>
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.<br>
<br>
I think eventually it will be effective in cutting down the number of rogue callers and catching the ones that are egregious offenders.<br>

This one of the things being worked out. There are frameworks for <br>

Awesome to hear Calvin. I was under the impression that the STIR/SHAKEN <br>
standard had been ratified by the participating carriers and they were <br>
moving forward. I have not seen anything about cert delecation and TN <br>
authorization in the technical specs. <br>
<br>
Is STIR/SHAKEN not really completed and ready for deployment yet? The FCC <br>
and larger carriers seem to be moving forward with test implementations <br>
without of TN authorization and delegation. <br>
