When calling from a land line, your physical address is only as good as the phone records. Which, to be fair, are usually quite good, but not imperfect. If you call from a house phone, our system is recognizing the address that the phone number is registered to, which is some cases is not always accurate. This is especially true when dealing with “routing” lines and large business network lines. If your business phones pass through a network router, the address of the business line may not be the same as where you are calling from.
VoIP phones also run a similar system of address registration. When you sign up for the service, you enter an address for the account, and when that system dials 9-1-1, that’s what we see. You may not be anywhere nearby, but that’s the registered address. The shadier uses of this includes using a deliberate fake address to mislead emergency responders, but that is a different topic.
Now, cell phones. Ah, cell phones. In this day and age of phones smarter than my desktop computer, people assume we know everything about them when they call. When you call from a cell phone, the call is bounced off a cell tower and then placed here. When we pick it up, we can hope for two things. “Phase 1″, which is the location of the cell phone tower. Yep, the nearest cell tower, which could have an effective area of square miles. If we’re lucky, depending on the reception where you are and the kind of phone you’re using, we can get “Phase 2″, which gives us GPS coordinates of the approximate location of your cell phone. Sometimes these are pinpoint, and sometimes with an effective range of several thousand meters. So yes, we will ask you for the location of the incident, even though you are calling from your cell phone, and even though your phone can tell you its exact location three states away while in an underground solid lead bunker.
Plus, technology is all wonky and sometimes gets fickle and doesn’t do what its supposed to.
Well, I think that about does it for an introduction. Tune in (or tune out) the next installment, where I’ll explain why it took over a year to get hired here.
