Emergency telephone number Guide, Meaning , Facts, Information and Description
Many countries' public telephone networkss have a single emergency telephone number, sometimes known as the universal emergency telephone number or occasionally the emergency services number, that allows a caller to contact local emergency services for assistance. The emergency telephone number differs from country to country. It is typically a three-digit number (though not always), so that it can be easily remembered and dialed quickly. Some countries have a different emergency number for each of the different emergency services, these often differ only by the last digit.

The number is intended to be used only in an emergency.
For routine and non-urgent enquiries one should use the ordinary telephone numbers for the particular emergency service. These are normally listed in the local telephone directory. In the United Kingdom, for example, the number 0845 46 47 can also be dialed for NHS Direct, a non-emergency medical service. Routine and non-urgent calls as well as hoax or crank calls to emergency services numbers waste the time of both dispatchers and emergency responders and can endanger lives. False reports of emergencies are often prosecuted as crimes. If you need to call for help, the emergency services numbers are there to help you.
In the NANP (mainly the United States), 3-1-1 is the new urgent telephone number, that can be used to contact the police and other services to report minor incidents and historic crime that does not endanger life, to avoid overloading 9-1-1. Some cities also use 3-1-1 for contacting other municipal government services, or to report situations like power outages.
The emergency telephone number is a special case in the country's telephone number plan. In the past, calls to the emergency telephone number were often routed over special dedicated circuits, though with the advent of electronic exchanges these calls are now often mixed with ordinary telephone traffic, but may be able to access circuits that other traffic cannot. Often the system is set up so that once a call is made to an emergency telephone number, it must be answered. Should the caller abandon the call, the line may still be held until the emergency service answers and releases the call.
An emergency telephone number call may be answered by either a telephone operator or an emergency service dispatcher. Depending on the system used:
Generally it is best to allow the emergency dispatcher to control the call, as they are specially trained to do so. The emergency dispatcher may find it necessary to give urgent advice in life-threatening situations. Some dispatchers have special training in telling people how to perform first aid or even cardiopulmonary resuscitation.
In many parts of the world, an emergency service can identify the telephone number that a call has been placed from. This is normally done using the system that the telephone company uses to bill calls, rather than Caller ID. This means that emergency services can identify even unlisted telephone numbers. For an individual fixed landline telephone, the callers number can often be associated with the caller's address and therefore their location. However, with mobile phones and business telephones, the address may be a mailing address rather than the caller's location. The latest "enhanced" systems, such as Enhanced 911, are able to provide the physical location of mobile telephones. This is often specifically mandated in a country's legislation.
The first emergency number system to be deployed was in London, United Kingdom on June 30, 1937. When 999 was dialed, a buzzer sounded and a red light flashed in the exchange to attract an operator's attention. It was gradually extended to cover the entire country, but it was not until the late 1960s that the facility was available from every telephone.
In the days of loop disconnect dialing, attention was devoted to making the numbers difficult to dial accidentally by making them involve long sequences of pulses, such as with the UK 999 emergency number. This contrasts to modern times, where repeated sequences of numbers are easily dialed on mobile phones, particularly as mobile phones will dial an emergency number while the keypad is locked or even without a SIM card.
The North American 911 emergency phone system was set up in 1968, but was not in widespread use until the 1970s.
In France, in 1928, telephone operators had to connect the calls for emergency reasons even when the phone service was closed. In 1929, an automatic connection system is set up, initially for less than 10,000 people in Paris, allowing them to dial 18 to reach the fire brigade. The service was not widespread until the 1970s.
The CEPT recommended the use of 112 in 1972. The European Union subsequently adopted the 112 number as a standard on 29 July, 1991. It is now a valid emergency number throughout EU countries and in many other CEPT countries. It sometimes works in parallel with other emergency numbers in countries such as Britain and Ireland.
The GSM mobile phone standard includes 112 as an emergency number. This applies even if the local emergency number is different. This is convenient for people that travel to other countries and may not know the local emergency number. For example, some people have reported that 112 works on GSM networks in the United States.
On GSM networks, the number 112 has an advantage that it may work if the mobile phone is within the range of any GSM network, even if the one the phone is subscribed to is out of range, whereas the national emergency number often will not. For example, if I somewhere in Australia with an Optus GSM mobile phone, and there is Telstra but not Optus coverage in the area, if I dial 112, my mobile phone will try any reachable network to connect through (i.e. Telstra), but if I dial 000 (Australia's national emergency number), it will try to connect through Optus and fail, since the phone does not realise it is a special number.
According to: http://europa.eu.int/comm/environment/civil/pdfdocs/112surv-2001.pdf some GSM networks (e.g. in Belgium, Spain, UK, Liechtenstein) will only handle emergency calls from people with a valid account on their network e.g. customers and roamers only. Some GSM networks will not accept emergency calls from phones without a SIM card, or a SIM card with credit.
