New California bill could help curb 'neighbor spoofing' spam and scam robocalls

From the article:

> The new bill, SB 208, was introduced by Senator Ben Hueso (D.-San Diego) earlier this week. It effectively sets a deadline of July 1, 2020 as the date by which phone companies must "take the steps necessary to stop these illegal scams."

> ...

> The FCC had previously suggested phone companies utilize a system called the Secure Telephony Identity Revisited and Secure Handling of Asserted information using toKENs (STIR/SHAKEN), which helps law enforcement identify numbers attached to robocall efforts. However, no deadline has yet been legally set for these companies to take any official action.

Can a telephony expert comment on whether the California law is technically and/or economically feasible?

I really hope that the government will find a complete way to stop the usage of number spoofing for personal/business use. This technology become a popular (and easy) technique for criminals. I read thousands of reports filed at sites like http://whycall.me about this.

I don't know how a state can limit Caller-ID fakery via VOIP on its own.

VOIP connections in or to the US should have to provide a legitimate Caller-ID (actual origin # or corresponding switchboard accepting inbound calls) or blocked number, but never a false number.
