Quick post today, readers may remember that in the last post that the 112 test was today, so i hope you all set your alarms for this post!
imsd emergency calling works! end to end tested on the live network!
I called 112 in the designated time slot and had full two way voice with the operator, plus NAW data, sadly the AML did not work.
The Netherlands doesn’t use the text based AML my code had, ive send an email thanking them for the test and requesting information on the data based AML aswell as a possibility for a future second test when that works.
I do have to say that i can only say this works for the netherlands, i can tell the emergency path works in the modem and it took the genuine correct path, i can’t guarantee it. I’m not sure what the risk is that it works here but not elsewhere but i think its right to state this.
Before doing the first test i was so nervous with my phone hovering the call button but im glad it all worked out in the end, the operators were really kind too.
On the slight chance that any 112 operators happen to read this, Thank you very much!
what is NAW and AML?
NAW is the data the operator can get from the phone number, static data from the carrier subscription. It’s dutch for name, address, city.
AML is Advanced Mobile Location, a standard that allows your phone to send the GPS coordinates to the operator.
I wpold hope that if linux phones support AML that they have ways of disabling it.
Why so? IIRC it only sends to emergency services no?
I have no faith that ICE wouldn’t have access to the data from US dispatch offices
If I have understood correctly, it is only sent when you place an emergency call.
I think your concern should be more about the carriers sharing cell association data with them - as long as the phone is on, that can be used to track location pretty accurately.
But a toggle would be nice, I agree.
