An automatic number announcement circuit (ANAC) is a component of a central office of a telephone company that provides a service to installation and service technicians to determine the telephone number of a telephone line. The facility has a telephone number that may be called to listen to an automatic announcement that includes the caller's telephone number. The ANAC facility is useful primarily during the installation of landline telephones to quickly identify one of multiple wire pairs in a bundle or at a termination point.
911, sometimes written 9-1-1, is an emergency telephone number for Argentina, Canada, Dominican Republic, Jordan, Mexico, Pakistan, Palau, Panama, the Philippines, Sint Maarten, the United States, and Uruguay, as well as the North American Numbering Plan (NANP), one of eight N11 codes. Like other emergency numbers around the world, this number is only intended for use in emergency circumstances. Using it for any other purpose is a crime in most jurisdictions. Penalties for abuse/misuse of 911 can range from probation/community service to fines/jail time. Offenders can also be ordered to undergo counseling and have their use of telephones restricted or suspended for a period time as a condition of probation.
An emergency telephone number is a number that allows a caller to contact local emergency services for assistance. The emergency number differs from country to country; it is typically a three-digit number 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.
A dial tone is a telephony signal sent by a telephone exchange or private branch exchange (PBX) to a terminating device, such as a telephone, when an off-hook condition is detected. It indicates that the exchange is working and is ready to initiate a telephone call. The tone stops when the first dialed digit is recognized. If no digits are forthcoming, the partial dial procedure is invoked, often eliciting a special information tone and an intercept message, followed by the off-hook tone, requiring the caller to hang up and redial.

NHS 24 is Scotland's national telehealth and telecare organisation. This special health board runs a telephone advice and triage service that covers the out-of-hours period. The telephone service allows people who feel unwell or those caring for them to obtain health advice and information if it is not convenient or possible to wait until they can visit their general practitioner when the practice is next open. The advice line is not intended as a substitute for obtaining an emergency ambulance service via 999. The telehealth services provided by NHS Scotland fulfil some similar functions to NHS Direct Wales and the NHS 111 scheme in England.
Pocket dialing is the accidental placement of a call on a mobile phone or cordless phone located in the owner's pocket or handbag. The recipient of the call typically hears random background noise when answering the phone. If the caller remains unaware, the recipient will sometimes overhear whatever is happening in the caller's vicinity. A pocket-dialed call can continue for many minutes, or until the recipient's voice mail system ends the call.
A telephone number in Belgium is a sequence of nine or ten digits dialed on a telephone to make a call on the Belgian telephone network.

Hazel Blears, then a UK government minister in the Home Office, stated that the new system would "strengthen community engagement". In 2004, ten million 999 calls were made in the UK; however, 70% of those calls were deemed not to be an emergency.
