Let's get real, here - this problem is vastly overblown. 

Any system which isn't set up to check for the local country code is going
to have far more problems than just a call to emergency services, it will
think the whole world is a local call. Depending upon the way the local
telco works, that will cause all calls to fail, all calls to go through,
local calls to fail while in-country long distance calls go through, etc.

A working system in Oz would first look for and strip the country code for
OZ (61). If it doesn't do that, then the system will never be able to call
other systems in Oz. Then it would have to check for and strip the local
area code, or it would never be able to make local calls. If the system
isn't configured at least that well, the very first test call will fail.

Then it would have to prefix phone numbers from other area codes with
"1" in order to make non-local calls. Calls to other country
codes would have to have a different prefix to access an international
line.

How would "000-" ever get through that unchanged?
