[AusNOG] "Telstra" scammers still at it...

[Shaun Deans]

Random thought experiment... as both someone who's worked in carrier
networks and in software what ponders me is...

If my Google Phone app can detect a scammer and tell me before I answer why
can't a carrier (source or destination) ?

I understand Google has a massive dataset which the humans feed (for
"free") every day. But I'm sure they just live to offer a service to
carrier's for 'extreme scammers' back to carrier's. I understand the CLIR
is faked but logs would show it originating.

But as someone else said the scammers' will still pay for the calls. 🤔

The current projects stopping of overstamping CLIRs outside the network
coming back inbound will help immensely.

As someone with experience on both sides (Net & Dev) I'd love to geek out
pro-bono on a project.

That said I'm sure Telstra has smarter gals & guys than me trying to crack
the code.

Just 2c
