Malicious Caller Identification
Malicious caller identification, introduced in 1992 as Call Trace, also called malicious call trace or caller-activated malicious call trace, is activated by the vertical service code *57 ("star fifty-seven"), and is an upcharge fee subscription service offered by telephone company providers which, when dialed immediately after a malicious call, records metadata for police follow-up. Generally, law enforcement will only act on the trace once a formal police report has been filed in regard to the call. Malicious caller identification, when subscribed or enabled, works by allowing a phone call recipient to mark or flag the preceding phone call connection as malicious (i.e. harassing, threatening, obscene, etc.). The phone system will then automatically trace the call by flagging station to station billing and routing data including start and end times. The call trace is not dependent upon call duration (as envisioned in dramatic movie plots) and will record all meta-data regardle ...

Vertical Service Code
A vertical service code (VSC) is a sequence of digits and the signals star () and pound/hash () dialed on a telephone keypad or rotary dial to access certain telephone service features. Some vertical service codes require dialing of a telephone number after the code sequence. On a touch tone telephone, the codes are usually initiated with the star key, resulting in the commonly used name ''star codes''. On rotary dial telephones, the star is replaced by dialing ''11''. In North American telephony, VSCs were developed by the American Telephone and Telegraph Company (AT&T) as Custom Local Area Signaling Services (CLASS or LASS) codes in the 1960s and 70s. Their use became ubiquitous throughout the 1990s and eventually became a recognized standard. As ''CLASS'' was an AT&T trademark, the term ''vertical service code'' was adopted by the North American Numbering Plan Administration. The use of ''vertical'' is a somewhat dated reference to older switching methods and the fact that t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upcharge
Upcharge is used as the billing counterpart to marketing's upsell.\\ The term may refer to: * Paying a smaller increment in price for a larger increase in what is received; in another it means paying an increase for a non-standard arrangement, what one writer called "upcharge money." * A convenience fee: a pharmacy that carries basic grocery items and charges higher prices for the non-pharmaceutical one-stop-shopping items. While a surcharge is part of what must be paid, an upcharge is not always unexpected, and usually can be declined by rejecting the additional service or the suggested upgrade, albeit receiving less.

Obscene Phone Call
An obscene phone call is an unsolicited telephone call where a person uses profane and/or sexual language to interact with someone who may be known to them or may be a complete stranger. Making obscene telephone calls for sexual arousal or other sexual pleasure is known as telephone scatologia and is considered a form of exhibitionism. Status as a paraphilia Telephone scatologia is usually classed as a paraphilia from a psychiatric viewpoint. It is in the DSM-5 as an other specified paraphilic disorder. Related psychiatric terms (such as ''coprophilia'') were coined in Australia, the United States, and Germany; most of the pertinent literature is North American. From the viewpoint of the recipient of the calls, obscene calls may be considered to be a form of sexual harassment, stalking, or both. Legal consequences In some U.S. states, making obscene telephone calls is a Class 1 Misdemeanor. In the United Kingdom, obscene phone calls are punishable by a fine of up to £5,000 ...

Unlisted Number
In telephony, an unlisted number (United States, New Zealand), ex-directory number (United Kingdom) silent number, silent line (Australia), or private number (New Zealand, and Canada) is a telephone number that, for a fee, is intentionally not listed in telephone books. Although an unpublished number is not included in the phone book, an unlisted number may be available from the phone company's information operator. When used for residential households, they're primarily for privacy concerns.NYTimes: "includes the last four digits" of a person's address. Another form of anonymity is being listed with just a first initial, for those with a relatively common family name; sometimes these listings also lack an address. No fee is charged for initially being so-listed. Unlisted numbers as a paid service NYNEX was charging $1.95 per month in 1994; in 1976 the same service was 93 cents monthly. In 1971 ''The New York Times'' wrote that some users of this service needed it to hide from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Payphone
A payphone (alternative spelling: pay phone or pay telephone or public phone) is typically a coin-operated public telephone, often located in a telephone booth or in high-traffic public areas. Prepayment is required by inserting coins or telephone tokens, swiping a credit or debit card, or using a telephone card. The company that operates the payphone generally pays either rent or a revenue share to the owner of the property where the phone is installed. Invented in the late 19th century, payphones became ubiquitous worldwide in the 20th, enough to contribute to the notion of universal access to basic communication services. The charge for a call may be a flat rate, or dependent on call duration. Following the explosive growth of mobile telephony, the use of payphones, and the number installed, has decreased greatly. Countries Canada Most payphones in Canada are owned and operated by large telecom providers such as Bell, Telus Communications, and SaskTel. In the last 2 ...

DTMF
Dual-tone multi-frequency (DTMF) signaling is a telecommunication signaling system using the voice-frequency band over telephone lines between telephone equipment and other communications devices and switching centers. DTMF was first developed in the Bell System in the United States, and became known under the trademark Touch-Tone for use in push-button telephones, starting in 1963. The DTMF frequencies are standardized in ITU-T Recommendation Q.23. The signaling system is also known as ''MF4'' in the United Kingdom, as ''MFV'' in Germany, and ''Digitone'' in Canada. Touch-tone dialing with a telephone keypad gradually replaced the use of rotary dials and has become the industry standard in telephony to control equipment and signal user intent. The signaling on trunks in the telephone network uses a different type of multi-frequency signaling. Multifrequency signaling Before the development of DTMF, telephone numbers were dialed with rotary dials for loop-disconnect (LD) ...

Plain Old Telephone Service
Plain old telephone service (POTS), or publicly offered telephone service, is basic Voice band, voice-grade telephone service. Historically, POTS has been delivered by Analog signal, analog signal transmission over copper loops, but the term also describes Backward compatibility, backward-compatible analog connections offered by digital telephone systems. Copper loop POTS was the standard service offering from telephone companies in the United States from 1876 until 1988, when the Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) was introduced, followed by the development of mobile phone, cellular telephone systems and voice over internet protocol (VoIP). Despite the advent of these technologies, copper loop POTS remains a basic form of residential and small business connection to the telephone network in many parts of the world. The term encapsulates a technology that has been available since the introduction of the public telephone system in the late 19th c ...

ISDN
Integrated Services Digital Network (ISDN) is a set of communication standards for simultaneous digital transmission of voice, video, data, and other network services over the digitalised circuits of the public switched telephone network. Work on the standard began in 1980 at Bell Labs and was formally standardized in 1988 in the CCITT "Red Book". By the time the standard was released, newer networking systems with much greater speeds were available, and ISDN saw relatively little uptake in the wider market. One estimate suggests ISDN use peaked at a worldwide total of 25 million subscribers at a time when 1.3 billion analog lines were in use. ISDN has largely been replaced with digital subscriber line (DSL) systems of much higher performance. Prior to ISDN, the telephone system consisted of digital links like T1/ E1 on the long-distance lines between telephone company offices and analog signals on copper telephone wires to the customers, the " last mile". At the time, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Customer-premises Equipment
In telecommunications, a customer-premises equipment or customer-provided equipment (CPE) is any terminal and associated equipment located at a subscriber's premises and connected with a carrier's telecommunication circuit at the demarcation point ("demarc"). The demarc is a point established in a building or complex to separate customer equipment from the equipment located in either the distribution infrastructure or central office of the communications service provider. CPE generally refers to devices such as telephones, routers, network switches, residential gateways (RG), set-top boxes, fixed mobile convergence products, home networking adapters and Internet access gateways that enable consumers to access providers' communication services and distribute them in a residence or enterprise with a local area network (LAN). A CPE can be an active equipment, as the ones mentioned above, or passive equipment such as analog telephone adapters (ATA) or xDSL-splitters. This i ...

PABX
A business telephone system is a telephone system typically used in business environments, encompassing the range of technology from the key telephone system (KTS) to the private branch exchange (PBX). A business telephone system differs from an installation of several telephones with multiple central office (CO) lines in that the CO lines used are directly controllable in key telephone systems from multiple telephone stations, and that such a system often provides additional features for call handling. Business telephone systems are often broadly classified into key telephone systems and private branch exchanges, but many combinations (hybrid telephone systems) exist. A key telephone system was originally distinguished from a private branch exchange in that it did not require an operator or attendant at a switchboard to establish connections between the central office trunks and stations, or between stations. Technologically, private branch exchanges share lineage with central ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
