dialling 0+0, plus another 0 would call (at least) an operator. Zero is also the closest to the finger stall on rotary dial phones making it easy to dial at night or in smoke. It is now well established nationally throughout Australia that persons requiring emergency assistance dial 000. Calling 000 Within Australia, 000 is a free call from most telephones. Dialling 000 (or 112) on most Australian GSM mobile phones will override any keypad lock, and if the caller's home network is out of range, the phone will attempt to use other carriers' networks to relay the call. A SIM card is not required to connect a mobile phone to the emergency numbers. Interpreter services may be available once connected to emergency services. Due to special configuration in their firmware, some 3G or GSM mobile phones sold in Australia will redirect other emergency telephone numbers, such as 911 and 999, to 000. These calls are sent out by the handset as an emergency flag to the network, and as such, are treated in the same way as a call to 000. Answering Calling 000 greets the caller with a recorded message stating "You have dialled emergency Triple Zero, your call is being connected", then connects the caller to a Telstra operator who will then connect the caller to the emergency service organisation call taker. Telstra operators will ask the caller which specific emergency service they require by saying: "Emergency. Police, fire, or ambulance?", along with asking for their location if not calling from a phone with fixed location (landline). The caller is then connected to the emergency service requested by the caller. As soon as the emergency service call taker answers the call, any available caller location information, ascertained by automatically accessing a special database from the calling line identification (CLI) data that is provided with all emergency calls, is transferred to the emergency service; however, the emergency service call taker will still question the caller to obtain correct location details to dispatch the correct response. The caller's address is usually available to Telstra operators for fixed services in Australia even if the number is "private". However, emergency service organisation call takers will always ask for the address of the emergency to be stated whenever possible to ensure an accurate location is provided – this is especially relevant in the case of "third-party" callers who are not personally on
