On the topic question, I'd suggest we look at both directions of the trust gap: spoofed calls coming to 911, and legitimate public-safety calls going out that never reach the person they're meant for.</div>

For those I didn't meet I'm with DICE Corporation, which builds automation software for alarm monitoring central stations and is a vetting agent for CTIA's Branded Calling ID, and IPtelX, a registered carrier specializing in alarm signaling also operating as
a BCID signing agent and OSP.</div>

Alarm central stations work in front of the PSAP. Before a station asks for a dispatch, it calls the homeowner or keyholder to verify the alarm, and many jurisdictions require this. Those calls are short, high-volume, and come from a small pool of numbers,
which is exactly the pattern analytics engines treat as robocalling. When the verification call is blocked, labeled as spam, or lands in the wrong voicemail, the station can't rule out a false alarm, so police are dispatched to a home where nothing is wrong.
The best outcome is a wasted response and a false alarm fine for the homeowner. The worst is a tense armed encounter on private property that never needed to happen. It's the same failure Orlando described that response resources consumed because call trust
broke down, only coming from the other direction.</div>
