My understanding is that the only VOIP carriers that can get an IPES OCN
are Interconnected VOIP carriers. You have to get a certification from
the FCC to become an Interconnected VOIP carrier because the
Interconnected VOIP status allows you to order and manager your own
NXXs.
The main network difference between a CLEC and an Interconnected VOIP
carrier is that the CLEC has a direct connection to the PSTN via their
own SS7 links and direct trunks to the ILEC. The Interconnected VOIP
carrier gets their connection to the PSTN through a third party carrier
that manages the SS7 links and direct trunks to the ILEC.

Glen,
What are we to do for our clients who have DID/TFN from 3rd paries? We
won't have any relationship with their DID provider to request a
delegated certificate, and wouldn't have one of our own to sign those
calls, even as Attestation level B or C. Does the client need to
request a delegated cert and provide it to each termination carrier
they want to use?
I had a call with Bandwidth today was told the delegated certificates
would need to contain (or refer via URL) a list of which numbers are
permitted to be signed by that cert. I hope they've considered the
potential information leak here and use hashes of the permitted
numbers, not the numbers in cleartext.
For what it's worth, I received confirmation from NECA that an IPES
OCN can be issued without an FCC waiver. This would at least let us
sign with level B or C.
Query to NECA and their reply:
Assuming I will need an OCN, I have been told that VoIP carriers that
are not certified by
the FCC as Interconnected VoIP carriers cannot be assigned an OCN.
This doesn't jive with the lingo on your website:
IPES service: Proof of service and customers, e.g., interconnection
agreement (or evidence of an interconnection order pursuant to an
approved tariff) and contractual agreements with end-user customers.
Or, regulatory administration approval, if applicable.
We definitely have contracted customers and definitely have
interconnections with DID/TFN origination carriers and termination
carriers. If we have no intention to obtain numbering resources
directly, can we still obtain an OCN?
YES, YOU CAN STILL OBTAIN AN OCN.

Yes, I believe that is the case today. In the new "delegated
certificate" model the VoIP provider (or CPaaS provider) will be
provided a certificate from the OCN that is used for the ANI. This
delegated certificate will give the downstream carriers A level
Attestation for the calls regardless of where the outbound calls are
originated.
Ultimately it is the originating Enterprise that needs to be
traceable from the terminating carrier. Once this relationship chain
has been vetted the certificates can be delegated and used at call
set up time. NetNumber has a service for brokering the Certificates
but the spec is not fully adopted to my knowledge.
Another proposal at ATIS is to have the sending CNAM (and expanded
eCNAM) validated with a similar vetted relationship and certificate
chain. Ultimately this may be more useful for both the Enterprise
and the Callee than just the ANI.

So it sounds to me like you just have to be a certified carrier to
get a STIR/SHAKEN certificate. That means either a CLEC, Wireless,
or Interconnected VOIP Carrier. The VOIP carriers that are not
certified by the FCC as Interconnected VOIP carriers cannot be
assigned an OCN.

As explained to me by TransNexus, the Certificate Authorities will
most likely require an OCN. VoIP carriers with their own numbering
resources already have their IPES category OCN. It's also possible
they might only require a SPID.

Alex,
You would think so. From what I understand you will need to be a LEC
to get a cert.

If non-LEC VoIP providers can direct own numbering resources now,
it follows that they should be able to partake of STIR/SHAKEN.

As I understand it if one wants to get a cert for STIR shaken
you need to become a CLEC. Anyone have a how to/contacts for
companies that make this effortless and easy?
