It's common to set systems up so that any emergency numbers dialed go to the local emergency number. Our dialing plan directed at least 112, 911 and 999 that way, I'm not sure about the others. A combination of trying to do the right thing and liability issues means that you tend to be over caution when trying to work out if something should be an emergency call. Even though it's really expensive for the carrier it's better to do that than fail to connect a real call. There's also the issue of testing, and putting the same emergency rules on every handset means that you remove one failure point from the chain (making sure the right software version is shipped to the right country).
