999 or 112 emergency calls
•  Your Cloud Voice number is registered to a specific address, so 
when you make a 999 or 112 call from your phone number, 
that’s the address the emergency services will see.
•  If you use Cloud Voice at a different address, the registered 
address won’t automatically change. So if your work location 
changes, please let your administrator know so they can update 
your registered address. 
•  You might not be able to make 999 or 112 calls if there’s a 
power or network failure, or you’re using the service from an 
app or mobile phone.
