In North America, the PSAPs tell us that their priorities are to:
1. Get the call to the right PSAP
2. Get a call back number
3. Get the location of the caller
To the extent that the current PSTN equates "identity" of the
caller with
the telephone number, they are getting identity as their second point.
This discussion is more or less out of charter, as the work in ecrit
addresses the first point above.
For ecrit, we did have a discussion on the importance of assuring
that the
location provided is the actual location of the caller. This is
actually
the biggest part of addressing prank calls.
As I said in the meeting, the PSAPs I know would accept a call with no
location, no call back and no identity. They might be VERY
suspicious of
such a call, but they will take it, and depending on what the
caller said,
they probably will dispatch someone. At least for the PSAPs I
know, while
they will demand a lot of effort to make sure location and call
back are
accurate, they will, in fact, accept a call without it. In that
regard, I
think they care about the house on fire first, and the identity
second.

Subject: [Ecrit] some observations from yesterday wg meeting
I am not a regular on this list so whatever I said here is based on
what I see at yesterday wg meeting. Pardon me if these already been
discussed.
1. There are a lot of talks about how caller can authenticate the
emergency response centers (singapore term for what WG's called PSAP)
but not much talks about how PSAP is going to authenticate the
callers.
Considering how many prank calls typical PSAP gets, I wont be
surprised if their priority is to identify the caller first and less
about your house on fire.
No I am serious. That's my experience when dealing with them on E911
when we are working on our IP Telephony framework.
2. Any bet how long it will take PSAP to install a SIP server into
their system? Especially a system which will allow anyone from
anywhere in the world to call them anonymously?
So while it is important for the caller to be able to identify his
nearest PSAP, it is equally important for PSAP to be able to (a)
identify the caller and (b) establish that the caller is within the
zone they are serving.
