Dial 999

999 was actually choosen because of the old pulse dialling system.
In rainy weather it was actually possible for drops of rain to "false dial" 111.
So 999 was choosen as the same thing couldn't happen.
 
Whats the number you ring again when its not an emergency but you still want police or an ambulance, fire brigade. To a lesser degree. ie: Cat stuck in a tree, rather than baby stuck in a burning house.

edit, haha Tefal.

Your local station.
Some people think it's 112, but this is tosh.
 
So after a rather interesting debate in the office about taking presents back, someone then asked about dialling 999 in an emergency.

Someone has raised the point of you should dial 112 instead as the emergency services can track you via satellite through the 112 number, but they can't if you dial 999.

Anyone offer any real substance to this? A quick Google search doesn't really enlighten me much.

I can say catagorically that it's not the case. I work in an Emergency Services control room, trust me it would make my job about 50x easier if we could track you via Satellite.

Most landlines will have CLI information attatched to it (Caller Line ID) and will be presented on the CAD system when the call is connected to the emergency services (Theres only certain companies that can't do this and we have to contact them directly for information if the line drops out) This is great as if you ring from a Pay Phone we normally know instantly where you are. It's still down to the caller to confirm this information though.

Mobile phones however are a much different story.

As you know mobile phones are connected to masts, these masts can be used to triangulate where you are sometimes within a few hundred meters but it's not failsafe.

aa....and no where near as accurate as the Super Emergency Services Satellite we have in orbit ;)

Just to bring it back a little; this passes as interesting debate in your office :p?

Well it was more about how if someone was bought a matching present by work and your partner, would your partner be mad if you returned the one they bought instead of the one your work colleagues bought you.

Item in question is a piece of £100+ jewelry.
 
I think the people in the op's office may be getting a little confused between UK phones and US ones :p
IIRC due to an FCC law in the States all cell phones over there have had GPS fitted as standard for the last 5 years or so to allow for them to be tracked when someone dials 911
I think the US law requires cell phone companies to be able to provide the handsets location to within something like 50m, and the easiest way to do that is via a basic GPS system (probably not as capable as normal GPS, but if you can pick up just 2 or 3 GPS satellites* you can get a reasonable lock, if you're also picking up a ground station such as a cell phone tower).

For landlines it's done via reverse directory look up or something similar, basically the emergency services have a list of the physical addresses of all landline numbers (provided by law by the phone companies), so when they get a call it shows the address provided. IIRC some of the phone companies got into trouble when it turned out they weren't supplying accurate/up to date lists.



*As opposed to your Tomtom or Garmin which will generally need at least 3-4 for a reasonable fix, and often try to lock onto up to 10 at a time.
