The big telecoms get call traffic from a manageably small number of interconnect companies/organizations.

They probably can’t figure out the initial source, but they can figure out which interconnect it’s coming from.

They should call them at their 24/7 NOC and tell them to trace it back a later to trace back another layer to trace it back another layer. Or else they’re getting shutdown in 24hrs.

Same as AT&T would do if Cogent was sending them spoofed scam traffic.

The problem is that the telecoms get paid for these 4th string interconnects by the minute.

And some of the telcos now offer scam call blocking as a premium add on to customers.
