emergancy calls (Kathy)

I started to research into what people say when answering an emergancy call, however obviously i couldnt get this information 1st hand, so i looked at youtube clips and watched serveral episodes of crimewatch.
The majority of the calls said: "This is the emergancy services which service do you require... This is the police, how can we help you?" which was helpful as we can now use some of this dialogue in the police call for our film opening.

In the crimewatch episodes they say "hello, this is the police.... calm down, can you tell me where you are?... i cant understand you, can you tell me whats happened?"

So basically they say whatever they can to calm the caller down so they can gather all the information they need to send out the police as soon as they can. This information i found was all repetitive, and hard to find becuase the calls are only posted if they are hoaxes and so the ones i found were all the same calls.
All the calls have well spoken and easy to hear and understand people on the other end of the phone so that the victim/ witness can concentrate on giving information rather than trying to understand the employee.
