If this is baked into telephony, why we don't have this problem in Europe? (genuinely curious why this happens in the USA but not here)

- ggm 5y agoWe do have it in Australia fwiw
- marcus_holmes 5y agoI used to live in Perth, and never had this problem this bad. I got the occasional spam text, but it was usually from some company I'd given my number to. Are you getting that many spam texts?
- ggm 5y agoI get 2-3 spam texts and calls per month. About 1/2 fake my mobile # off by 1 digit near the end, a trick to make me "think its a number I know" I'm on ALDI which is an MVNO overlay on Telstra wholesale. Maybe ALDI do worse for source detect? (there is no difference between SMS and calls in regard to CLI faking. I don't know about RCS, its possible RCS gets rid of this problem. ALDI doesn't have RCS, its not ubiquitous, has to be enabled in the phone profile by the provider)
- willis936 5y agoIt sounds like it shouldn't even be happening in USA. It's a trivial bit of code in the routing software to check if CLI matches SS7. If it doesn't: don't connect. You don't even need to correct it. There's no legitimate reason to connect a spoofed number.
- riskable 5y agoIt is trivial to implement. They don't do it because they make a ton of money every year selling origin spoofing to businesses and charging customers for incoming texts (they never asked for). Spoofing is a service that the telcoms offer. Not a weakness! At least, that's how they see it.
