Call Screening
Call screening is the process of evaluating the characteristics of a telephone call before deciding how or whether to answer it. Some methods may include: * listening to the message being recorded on an answering machine or voice mail. * checking a caller ID display to see who or where the call is from. * checking the time or date which a call or message was received. * prescreening callers to a request line at a radio station or call-in talk show A talk show is a television programming, radio programming or podcast genre structured around the act of spontaneous conversation.Bernard M.

Telephone Call
A telephone call, phone call, voice call, or simply a call, is the effective use of a connection over a telephone network between the calling party and the called party. Telephone calls are the form of human communication that was first enabled by the development of the telephone and several inventions in the mid- to late-19th century. Initial technology involved point-to-point electrical wire connections between telephone installations, until centralized exchanges evolved where Switchboard operator, telephone operators established each interconnection manually at a telephone switchboard after asking the calling party for their call destination. After the invention of automatic telephone exchanges in the 1890s, the process became increasingly automated, eventually leading to the widespread adoption of digital exchanges in the second half of the 20th century, including the transition to wireless communication via mobile telephone networks and cellular networks.

Answering Machine
An answering machine, answerphone, or message machine, also known as telephone messaging machine (or TAM) in the United Kingdom, UK and some Commonwealth countries, ansaphone or ansafone (from a trade name), or telephone answering device (TAD), is used for answering telephone calls and recording callers' messages. When a telephone rings a set number of times predetermined by the call's recipient the answering machine will activate and play either a generic announcement or a customized greeting created by the recipient. Unlike voicemail, an answering machine is placed at the user's premises alongside—or incorporated within—the user's landline telephone, and unlike operator messaging, the caller does not talk to a human. As landlines become less important due to the shift to cell phone technology, and as unified communications evolve, the installed base of TADs is shrinking. History Most 20th-century answering machines used magnetic recording, which Valdemar Poulsen invent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voice Mail
A voicemail system (also known as voice message or voice bank) is a computer-based system that allows callers to leave a Voice recording, recorded message when the recipient has been unable (or unwilling) to answer the Telephone, phone. Calls may be directed to voicemail manually or automatically. The caller is prompted to leave a message that the recipient can retrieve at a later time. Voicemail can be used for personal calls, but more complex systems exist for companies and services to handle the volume of customer requests. The term is also used more broadly to denote ''any'' system of conveying stored telecommunications voice messages, including using older technology like answering machine, answering machines. Features Voicemail systems are designed to convey a caller's recorded audio message to a recipient. To do so they contain a user interface to select, play, and manage messages; a delivery method to either play or otherwise deliver the message; and a notification abi ...

Caller ID
Caller identification (Caller ID) is a telephone service, available in analog and digital telephone systems, including voice over IP (VoIP), that transmits a caller's telephone number to the called party's telephone equipment when the call is being set up. The caller ID service may include the transmission of a name associated with the calling telephone number, in a service called Calling Name Presentation (CNAM). The service was first defined in 1993 in International Telecommunication UnionTelecommunication Standardization Sector (ITU-T) Recommendation Q.731.3. The information received from the service is displayed on a telephone display screen, on a separately attached device, or on other displays, such as cable television sets when telephone and television service is provided by the same vendor. Value to society includes allowing suicide-prevention hotlines to quickly identify a caller, and enabling businesses (for an example, restaurants and florists) to quickly have co ...

Call Screener
A call screener or phone screener is a staff member who first answers the phone when audience members call into TV or radio broadcasts. For call-in talk shows, screeners determine the air quality of the call (good connection or not) and if the caller's comments will further the topic or add a new point. Their job is to put the best calls on the air and filter out the callers that don't have anything worthwhile to add to the conversation. They also try to engage callers by acting as a "warm up" act for the host. Call screeners also typically provide a summary of pertinent information for the host or hosts to provide context for on air interaction, such as the caller's name, age, gender, location and a precis of what they intend to talk about. During breaking news events, screeners are responsible for verifying the caller's identity, to ensure that correct information will be presented to the news anchor. A failure here can allow an embarrassing on-air prank call through. Richard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Request Line
A request line is a telephone line which allows listeners to call a radio station, traditionally to request the disc jockey to play a specific piece of recorded music on-air. In the late 20th century, a large volume of listener requests for a specific song could help to turn it into a hit in the United States market. By the early 2000s, radio request line data was supplemented by a changing mix of other sources, such as online surveys, to help predict future hits. Telephone network Although only one telephone number is usually announced, major stations typically have line hunting, with the same number being directed to any available one of several lines within the hunt group. If there are no open lines, the calling party may receive a busy signal as with an ordinary telephone call, or sometimes the special information tones followed by a recorded announcement that "all circuits are busy, please try your call again later". In this case, the line often first gives that calle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calling Feature
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] |
TeleZapper
The TeleZapper is a device designed to reduce the number of telemarketing-related phone calls a household receives by imitating the tone signal normally played by a phone company to indicate a line has been disconnected. The Telezapper was created by Privacy Technologies. Background Telemarketing companies typically use predictive dialers to place many calls simultaneously. When the equipment detects that someone has answered one of the many calls it has made, it quickly transfers that call to an available agent. Unanswered calls, or numbers that are disconnected, are not transferred to agents and the call is terminated automatically. In this way, the agent is spared the time of dialing a call and waiting for an answer, and can simply speak to waiting calls that have been already set up. Additionally, if a number is determined to be disconnected, the equipment will usually mark that number as such and will not dial it again or as often. How it works The TeleZapper is an ap ...

STIR/SHAKEN
STIR/SHAKEN, or SHAKEN/STIR, is a suite of protocols and procedures intended to combat caller ID spoofing on public telephone networks. Caller ID spoofing is used by robocallers to mask their identity or to make it appear the call is from a legitimate source, often a nearby phone number with the same area code and exchange, or from well-known agencies like the Internal Revenue Service or Ontario Provincial Police. This sort of spoofing is common for calls originating from voice-over-IP (VoIP) systems, which can be located anywhere in the world. STIR, short for Secure Telephone Identity Revisited, has been defined as a series of RFC standards documents by a Working Group of the Internet Engineering Task Force. It works by adding a digital certificate to the Session Initiation Protocol information used to initiate and route calls in VoIP systems. The first public connection on the system, typically the VoIP service provider, examines the caller ID and compares it to a known list o ...

Telephone Service Enhanced Features
A telephone, colloquially referred to as a phone, is a telecommunications device that enables two or more users to conduct a conversation when they are too far apart to be easily heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via Electrical cable, cables and other communication channels to another telephone which reproduces the sound to the receiving user. The term is derived from and (, ''voice''), together meaning ''distant voice''. In 1876, Alexander Graham Bell was the first to be granted a United States patent for a device that produced clearly intelligible replication of the human voice at a second device. This instrument was further developed by many others, and became rapidly indispensable in business, government, and in households. The essential elements of a telephone are a microphone (''transmitter'') to speak into and an earphone (''receiver'') which reproduces the voice a ...
