And you also need a way to persuade the Ambulance Service not to 
terminate their calls via VoIP, or send dispatch instructions via 
public-IP over GSM (or whatever) to their vehicles.

Or the IP bits need to be assured as "good enough" that it doesn't 
matter.

It's perhaps three years since I heard that there was real possibility 
of some of the above. That stable door may be more open than you think.
