Re: [VoiceOps] Voice Peering

The challenge is how do you authenticate the end "carrier" or service provider? 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

My current vendor has a similar setup. One VPN endpoint and STP are in the same market. The other are 1k miles apart. No idea why they'd do that. It seems like it would introduce extra opportunities for failure. - Mike Hammett Intelligent Computing Solutions http://www.ics-il.com

We need BGP for VoIP! Wait no that's worse... /s Jokes aside, my understanding of the way people do VoIP routing for private peer interconnection is by looking up the OCN at call time and routing on that. That way you don't have to worry about verifying individual numbers, or keeping

Re: [VoiceOps] SS7 Landscape

You'd be better off getting into Sinch's (formerly Inteliquent) PSTN Connection service.InfoBip (formerly Peerless) and Wide Voice also offer PSTN connection services. It allows you to keep your own NXXs and interconnect with the ILECs through their SS7 switch so you don't need your own.

I think that, as has always been the case with these ideas, fascinating technical intricacies miss the forest for the trees; the economics just don't bear out. The time to try this was in the 2000s. Boat's gone. By this point, there has been an enormous amount of industry consolidation. A very

There was a project, ENUMER, to put DIDs in a blockchain and an ENUM server lookup frontend to it to facilitate peering. I didn't saw many entries in the database back when it launched. I haven't looked in a while and don't remember which blockchain it was on. I believe TNS and Neustar operate a

Vonage was originally formed as the Minutes Exchange for voip peering. We then spun part of the free world dialup into iPeerX around 2005; sold it to Eli Katz a few years later. The key problems at the time were: 1. there were too few ITSP numbers to make the effort worthwhile; The

Re: [VoiceOps] Voice Peering

Maybe the signup fee, and lookup time is what killed the idea? If that's the case, we could solve it by downloading the list preemptively, for the signup we could use some cheap hosting, and instead verifying it with crypto. We could possibly cryptographically verify it by showing a STIR/SHAKEN

I think the realistic responses are going to be some combination of: 1) "Congratulations, you just invented Neutral Tandem/Inteliquent/whatever they are this week" 2) "The SIP peering exchange has been proclaimed every year since the early 2000s" 3) "This is quietly happening for years now
