In Canada and the USA they would dial 911
In the UK they would dial 999
In Europe they would dial 112 or possibly one of the various
legacy national numbers for emergency service.
And in Australia they would dial 000.

Do you route all these calls to Britain?  Do you use some sort of
geographical locator database for IP addresses to route the call?
Do you route the call based on the actual number dialed, i.e. all
000 calls go to Australia?

Sounds like a perfect job for anycast.

I dont know how VoIP URIs work, but if there's DNS mapping involved 
surely you can set up the appropriate records for _all_ the various 
types of emergency number formats to map to the same anycast address.
