Carlos, Nifty; thanks. Unfortunately, I tried calling via 2 different carriers who both pass through Identity headers if supplied, but got No-TN-Validation result both times, implying that the PASSporT is getting stripped out somewhere along the way. Your number looks to be supplied by Level3, so a bit surprised at this result since I know for a fact both of the services I tried have direct relationships with L3 & so I would think that they'd look-up LRN & then try to send the call direct to them rather than punt it to their LCRs, but *shrug*.
I don't have direct access to L3/Lumen term...any chance I can send the INVITE directly to an SBC on your side to just bypass the problematic path(s)? (I presume I'd have to supply you with an IP on our side for you to whitelist...) If I get a failed validation result from the service, is it possible for somebody at Sansay look up on your side what specific part of the validation failed for a given call? At the moment, here is where I stand: Found a Voxbeam number (302-257-7304) that will read back attestation level. This will read back exactly the attestation level that I supply in the PASSporT that I attach to the call, but it "works" regardless of whether I'm using self-signed testing cert or an actual, valid SHAKEN cert. So this service doesn't actually seem to be validating anything. At least I know that Identity header is making it all the way there & that it's encoded properly... IDT's service, on the other hand, will show that validation passed and the correct attestation level if I do not transmit my own Identity header, and instead have upstream carrier attest it themselves. However, if I send our own Identity header using *either* our self-signed cert *or* our Sansay SHAKEN cert, I get "N/A - problematic" as the result, with no other explanation. If the Sansay testing service ends up having no problem validating our PASSporTs, that will be reassuring from one perspective, but concerning from another (why can IDT not validate any of our calls that we sign ourselves using our production cert, but Sansay can?). So I'm kinda rooting for the Sansay test service to fail when validating our calls... -- Nathan ________________________________ From: Carlos Perez <[email protected]> Sent: Monday, June 27, 2022 3:37 PM To: Nathan Anderson <[email protected]> Cc: Voiceops.org <[email protected]> Subject: Re: [VoiceOps] SHAKEN testing services Hi Nathan, We've put together something like you've requested (also open to the public) recently. In the future we will also provide the SPID in the report, right now you get the status of the validation (Passed, Failed, No Validation) and the attestation level. Feel free to dial +18586098097.

Although our own STI-VS can validate our own PASSporTs signed by our newly-minted private key, I want to verify what the world at-large is seeing before I flip the switch on for all outgoing calls (& potentially cause a bunch of problems if it turns out that something's wrong). So I'm envisioning something along the lines of a phone # one can call, and then get a report back of whether the terminating provider was able to validate the contents of the Identity header or not, and if not what the exact problem is. (Obviously the path between us and them would need to be IP end-to-end unless out-of-band SHAKEN is in place for the PSTN "glue" circuit.) I've found a couple, but the results for the ones I've tried (e.g., IDT BYOC) are woefully simplistic and don't really explain what went wrong if something does go wrong.
