Earlier quoted context omitted.
The question is: why is it possible to place a 911 call without all that information being laid bare before the dispatcher and logged. There are extraordinary regulations on carriers for E911, and thus a means to impose that requirement.
I'm hearing "let's block or delay 911 calls for [a reason]." Not sure that'll get a lot of traction. It's an awful problem that will exist as long as people suck.
Right now, you could have extra caution for 911 calls which originate from VoIP. Pass a law that in five years telco CEOs are charged as assisting murder the next time a SWATing happens and they’d magically discover that egress filtering is easy to implement once you’re not looking at the revenue generated by spammers.
