Over 50% of phone traffic is spam. Please, don't generalize. That statistic is maybe valid in the USA. In my case (Serbia) spam is practically 0%. There's an occasional landline call or two per month but that's enough for making fun by letting our kids answer the phone and troll the spammers. Third world "problems" (: Anyway, I support your fight against spammers.

Please don't generalize your own case either while you're at it.

Earlier quoted context omitted.

Same thing in France. I wonder if phone spam exists elsewhere than in USA (in UK perhaps) ?

In the Netherlands, I get called unsolicited and for marketing purposes maybe once a month. The call is always by a human, I’ve never been called by a robot. As soon as I notice it’s a marketing call I just hang up and if it’s not a hidden number, I add it to my “blocked numbers” contact, which I have blocked from incoming calls on my iPhone.

You could also GDPR the shit out of them... ;-)

People! You really need to get into politics or whatever and fix those things from a legal side!

You really need to stop inventing services and starting businesses for the most simple things in life!

edit: Don't get me wrong, I love the spirit, but there are _real_ problems to tackle and you are still working on stopping telephone spam? It's 2020, nobody should even think about things like that...

Congrats on launching! One security-related question: I had looked into this area previously as a user and a security-conscious friend pointed out that systems that use call forwarding to stop the spam problem are a HUGE security risk. You’re effectively man-in-the-middling all mobile calls, SMS, etc, and if there’s some sort of compromise (or, much less likely, malicious act) on your end, all of us users will be in…

Same thought here. I have been toying with the idea of building something OSS so that people could run it themselves, for this reason.

(Also I have what is possibly a common filtering case in the US that would eliminate 95% of my spam calls without blocking any relevant calls from "new" numbers. And for whatever reason, I have not seen it implemented anywhere yet.)

I built a whitelisting phone system for my aging dad with Twilio, an OBi200 VoIP adapter, and gcloud for transcribing untrusted calls sent to voicemail.

(US specific) If you think the aggressive IRS and Sheriff scams are bad -- you've committed a crime only $100 _right now_ will solve! -- the shakedowns targeting enfeebled senior citizens are truly sinister.

Which is to say, people who care for seniors (children of, part time caregivers, etc) are an unserved audience for tools like yours. I would have paid for one had it existed.

IF (area code == my area code) AND (prefix == my prefix) AND (last 4 != my last 4) THEN SPAM SPAM SPAM ?

Living in Germany I have received a total of 0 spam calls over several years.

That’s because there’s actually a law against it. I remember some years ago we always had Werbeanrufe on our landline. We don’t have a landline anymore but I’ve not gotten a single spam call for years now (except from my own home internet or mobile provider, which isn’t “spam” per se but still annoying because they sometimes call you five times a day instead of emailing you about some minor things).

What should we be thinking about ?

I'm in the process of open-sourcing the core part of a SaaS I run that does exactly this. It relies on Twilio but could be easily made to work with any API that exposes the forwarded number, which should be all of them.
