I get relentless text and phone spam calls - both robotic and with humans - from just a few voice over Internet platforms. Bandwidth.com, Neutral Tandem, and ALL the brands associated with Sinch (https://en.wikipedia.org/wiki/Sinch_AB) like Inteliquent. Many of these companies got cease and desist orders in the past from the FTC. It didn’t help anything. We need to see them fined, shut down, and executives jailed.

How would one discover which VOIP providers are the source of calls?

I wrote a little tool which can do lookups: https://github.com/evidlo/nanpa_lookup

There's no free source of this information anywhere. The only affordable option is telcodata.us

What do you do when these lookups return the company that owns the number but the company says that they are not in control of the number? E.g, I have one number that keeps harassing me that reports as Verizon but Verizon says they have not been with Verizon since 2024.

Also great tool, thank you

Did you get the data in the db from telcodata.us?

There are other sites like this. And then you can use the carrier info, go to that platform‘s website, and submit an abuse complaint through their form. But all they will do is possibly block that one spammer from contacting your phone number while continuing to allow the spammer to operate. And of course they have other spammers as customers.

Better option is to skip their abuse form and send complaints to your state’s AG, to the FTC website, and FCC website. They’ll ask for a lot of info but I think it helps them identify the problematic companies.

You can also forward spam texts to 7726 (“SPAM”) in the US, and your carrier will use that info to take action.

Yes, but its 3 years old and slightly stripped down.
