The fact is:

Skype is not interested where the client is located.
They dont care. Well, Skype is not a defined standard
but skype exits.

There are lots of VoIP telefones out. Do you really
want to call them back in to change the software?

How about tunnels? Do we have to rewrite all tunnel
software?

How do I know where that client with ip 192.168.48.226
(me) is located? NAT behind NAT behind NAT, some
packet-radio links and IPv6 over ISODE tunnels and
all that via SNA through an IBM company link.

No, my network is not really that complicated - but
I thought of a hamradio friend who is working at the
Georg-Von-Neumayer Antarctic Base.

Or simply think of an IP-phone used aboard an airplane
moving from Berlin to Abitibi-Témiscamingue (Québec).

You cannot change all phones out there.

You cannot change all public domain telephone software.

All you can do is tell your sip office to direct any
911 or 112 calls directly to the Vatican. Hopefully
they will have someone speaking the right language.
Probably they will have the right personnel to deal
with this kind of emergency.

A buddhist monastery in Tibet would do nicely too.
I think that is where the chinese route their calls :)

I know where my DSLAM is located. That is some 80 KM or say 40 miles
away from here. My link to that router is via PPPoE. There are some
switches, bridges and dont ask me what other hardware in between.

All that router knows is, I am one of 4K costumers connected.
It does not care where I plug in my DSL modem as long as I stay
some 150 KM around Frankfurt.

There are some 60 police callcenters within this area. I had already
the experience what it means when my GSM phone connects the
wrong one of them.

Of course whe have 112 service for cellurlar phones - only they wont
help you if you need them.

Just take the final two bytes of your ip and connect one of them
randomly. You probably hit the right one.

Why dialing a number? How about dialing an ip?
156.106.192.163 that is www.itu.int. They are the right
one to ask about telephone regulations anyway.

Cheers,
Peter
