RE: [Ecrit] some observations from yesterday wg meeting
It is even worse. In many countries you still may make emergency calls
from mobile phones without a SIM card. The majority of calls come
on Sunday morning from people buying mobile phones at the flea-markets
using 112 as test-number to check the device.
You may also reach the PSAPs from some countries (I wiLL
not tell which ;-) via an internatinal number. In most cases your CLI
is not delivered (and definitely not if you make a SkypeOut call)
So we should try to fix some of the problems existing now, but not
world hunger and save the whales. The important thing is, as Brian
not gets tired to state:
that you reach an PSAP if you need one.

Betreff: RE: [Ecrit] some observations from yesterday wg meeting
The issue you raise is not created by IP telephony.
The problem exists from the start of Pay as you go cellphones. There are now huge numbers of these phones circulating, all capable of making emergency calls, and large numbers of them totally untraceable back to an end user, due to various reasons like the user has moved (innocent) through to the user deliberately wanting a communication device that is untraceable so supplied false details to start off with.
However, even with this, I do not currently see the anything different from Brian's listed priorities.
