VoIP 911 "9-1-1 Do you need Police, Fire, or Ambulance?"
Caller "Ambulance"
VoIP 911 "Is your current address 555 Your Street in Big Town, Ontario?"
Caller "No - it's 444 New Street in Other Town, Alberta"
VoIP 911"Okay, please hold while I connect you"
(because it's a new address the dispatch has to lookup where to transfer
the call to)
VoIP 911 "I'm connecting the call, please stay on the line caller."
Ringing
Local 911 "9-1-1 Do you need Police, Fire, or Ambulance?"
VoIP 911 "Ambulance"
Local 911 "Okay, what is the emergency?"
VoIP 911 "I have a Voice over IP caller on the line from 444 New Street
in Other Town, Alberta. Is this your area?"
Local 911 "Yes it is."
VoIP 911 "Their call back number is 403-555-1234. Go ahead caller"
Caller and local dispatch communicate, and local dispatch usually
remains on the line until paramedics arrive giving any advise they can
and obtaining status updates on the situation for the paramedics as they
are on route.
The VoIP 911 dispatcher remains on the line to ensure the call completes
properly and is connected to the correct local dispatch centre.
The only time the registered address is used on it's own without
confirmation from the caller is when the caller hangs up, cannot speak,
or can't remember their address. In this case the local Police are
dispatched and it becomes their problem to follow up and determine if
there is an emergency or not.
From what I've read in the news it seems in this particular case when
the customer dialed 9-1-1 it rang five times with no answer. Someone
(customer service, perhaps?) called them back and asked if they were
okay. The person who called back promised to have an ambulance
dispatched. I haven't seen any details beyond this other than the CRTC
said they were looking for a recording of the 9-1-1 call to confirm that
current regulations were followed.
