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

[Chad Kelly]

Hi Just on this, the Telstra preventing CLIRs I am pretty sure this will prevent the scammers from using any Telstra numbers. 
>From what I understand the changes will prevent the use of Telstra numbers being used as caller IDs from outside of their network, previously the scammers have been able to use random mobile numbers they have found on the internet as the caller ID this will no longer be permitted on the network level once these changes go through. 
I understand from an ISP point of view that the only exception to this will be approved port out requests where Telstra has signed paperwork from the gaining  ISP to say the customer has approved to port their number out. 
>From how I understand this is being rolled out all other requests to make outbound calls from random Telstra numbers will be blocked at the network level.
Unless the number is on a Telstra account. 
This should help significantly with cutting down the amount of scam calls.

Regards Chad.

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
