The challenge is how do you authenticate the end "carrier" or service provider?
STIR/SHAKEN
Sure, anyone who leases numbers directly from NANPA can look up the carrier of record and exchange traffic directly, but any business who also leases numbers INDIRECTLY gets cut out and still needs to pay their upstream carrier(s) to place/receive calls, either by channels or per minute, even if their upstream is directly peered and not transiting the PSTN at all.
If this would be for the end user, then NANPA would have to delegate to the leasee, the leasee delegate to the reseller, the reseller to the end user, then the end user could publish their VoIP contact info, and anyone could call directly via VoIP, cutting out all of the middle peers.
But, as another person said, this is ripe for abuse, and with no motivation by NANPA or the larger carriers to make calls less expensive for the reseller or end user, I see this going nowhere. Until there is some value in NANPA (plus all the other country telephony organizations) and the direct carriers leasing numbers to do so.

I can think of a few ways that could be adapted into a platform more like an Internet exchange, but as others have said, it just doesn't seem worth it.

I think schemes like DUNDI (and some of the others mentioned here) suffer from a trust issue ? what?s to prevent operator X from poisoning the protocol with bogus ?stolen? numbers?

This was in another thread, but I broke it out into it's own conversation. Someone had asked:
--- I am joining this thread late, but, would anyone out there be interested in exchanging traffic with other carriers directly over SIP?
Just another point of VoIP history trivia at this point... but in addition to things like ENUM and ITAD, Mark Spencer of Asterisk fame also invented Dundi, which was an encrypted peer-to-peer protocol for route advertisement and discovery. As far as I know, very few people besides me ever put it in production, but it worked really well at the time. (Of course, it's been about 17 or 18 years now since I used it in production.)
