Isn't that pushing April Fool jokes a bit too close to the next day? People might actually take this seriously :P

I checked the URL's and the story appears valid.

Given that telco's can track call origin (they have to for emergency service and legal intercept reasons) I'd like to know why it takes so long to grab these people by the parts that hurt..

because telcos are NOT the victim, it's their clients. If they were... well, then obviously they'd be able to track and block by lunchtime. same business day. But to achieve the impossible business would need a strong incentive, like losing money, or a pesky judge shitting on them (v. Apple case ;)

Shitting from a great height upon cold-callers (whether DDoS or just nuisance) would be a far better use of judges' time than dealing with phone manufacturers suing each other over the shape of their corners.

WTF?

HSBC Call Centre sweatshops manage this already ...

by simply employing less than intelligent operators who take their sweet time in answering.

And they refuse written communications as deniability is not possible.

Wonder what sort of service standards the Mexican Laundry Service managed to maintain?

As for 'tracing' calls, all digital calls for over 15-20 years include all information needed including the call originator.

Yes, but..... the SS7 system assumes that everyone along the chain is trustworthy. There's even less concept of security in the world's phone switching network than there is in BGP. It only takes one bad actor to screw things up - and it's pretty clear there is way more than one bad actor with access to international routing systems.
