[VoiceOps] CLEC - STIR/SHAKEN

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.*
