In practice i can sign anything and it properly flags on comcast and tmo. There 
are totally legitimate circumstances (like forwarding a call) where you might 
attest C a call that isn't sourced from a number you own.

If we purchase our numbers through wholesalers, would we need delegated 
certificates if we are sending an outbound call through a vendor that is not 
the wholesaler we got the number from?

There is a STIR-SHAKEN process of registering and testing with the Policy
Administrator (PA) as a certified Service Provider (SP) before you can
purchase SHAKEN token certificates from a Certificate Authority (CA) and
begin to engage in using the technology. This is not a walk in the park.
Transnexus is one of two public CA's in the U.S. today. They are experts on
the subject and can help you through both processes. In order to get the
best call attestation you must prove to the PA and CA that you are a bono
fide service provider and not a bad-acting enterprise on a network that
deserves lesser attestation levels.

One of the registration requirements is a SP 's access to valid national
phone number pools. This has been very confusing for some resale providers
that purchase and use numbers from wholesalers only. If your organization
does not have it's own numbering resources, you can register using your
wholesale provider's numbering pool data. Don't assume you have to register
with the FCC and possess your own pool of numbers to become a registered
SHAKEN SP.

SHAKEN ROBO call mitigation is a new frontier, and obtaining the best
attestation level possible for a SP is essential to the SP and the SHAKEN
ecosystem. Register and test for the best attestation level possible.
Transnexus is a seasoned expert on the subject and a U.S. registered CA with
the PA.

I'm a Carrier Consultant who's been helping CLEC, IXC, Paging, Wireless and
VOIP carriers install and maintain their PSTN networks for the the last 20
years. I can help clients get their FCC Certification to become a
STIR/SHAKEN carrier as well as Numbering Resources, NPAC / LSR training, etc
(if you need those pieces). Once my clients get their certification, I refer
them to TransNexus. Jim and his team can help you with the process of
turning your STIR/SHAKEN services up.
