International Premium Rate Service
International premium rate service (IPRS) refers to internationally available telephone-based premium services. It is analogous to "900" or "976" numbers in North America, which always incur a recipient-defined charge in excess of regular call charges. Internationally, this service has been allocated country code +979. IPRS numbers are known as UIPRNs. The ITU recommendation for IPRS defines four charge categories, across which the +979 numbering space is divided: UIPRNs are only available to premium service providers who will provide their service to more than one country. The format of the numbers will be 979 a bcdefghi, where the a digit, 1, 3, 5 or 9, will indicate the charging band, and the remaining digits will be the IPRS subscriber's number. 1, 3 and 5 indicate charge bands 1, 2 and 3, respectively, while 9 will indicate a special charge band. The service is not yet known to be active. Once it is activated, it may not be available from every country, even though there ...

Premium-rate Telephone Number
Premium-rate telephone numbers are telephone numbers that charge callers higher price rates for select services, including information and entertainment. A portion of the call fees is paid to the service provider, allowing premium calls to be an additional source of revenue for businesses. Tech support, psychic hotlines, and adult chat lines (e.g. dating and phone sex) are among the most popular kinds of premium-rate phone services. Other services include directory enquiries, weather forecasts, competitions and ratings televoting (especially relating to television shows). Diplomatic services, such as the US Embassy in London or the UK Embassy in Washington, have also charged premium rates for calls from the general public. Premium calls are typically routed like toll-free numbers, and service providers can be located independent of the area code. These telephone numbers are usually allocated based on a national telephone numbering plan that makes them easily distinguishabl ...

NANP
The North American Numbering Plan (NANP) is a telephone numbering plan for twenty-five regions in twenty countries, primarily in North America and the Caribbean. This group is historically known as World Zone 1 and has the international calling code ''1''. Some North American countries, most notably Mexico, do not participate in the NANP. The NANP was originally devised in the 1940s by the American Telephone and Telegraph Company (AT&T) for the Bell System and the independent telephone operators in North America. The goal was to unify the diverse local numbering plans that had been established in the preceding decades and prepare the continent for direct-dialing of calls by customers without the involvement of telephone operators. AT&T continued to administer the numbering plan until the breakup of the Bell System, when administration was delegated to the North American Numbering Plan Administrator (NANPA), a service that has been procured from the private sector by the Fede ...

List Of Country Calling Codes
Country calling codes or country dial-in codes are telephone number prefixes for reaching telephone subscribers in the networks of the member countries or regions of the International Telecommunication Union (ITU). The codes are defined by the ITU-T in standards E.123 and E.164. The prefixes enable international direct dialing (IDD) and are also referred to as ''international subscriber dialing'' (ISD) codes. Country codes are a component of the international telephone numbering plan and are necessary only when dialing a telephone number to establish a call to another country. Country codes are dialed before the national telephone number. By convention, international telephone numbers are represented by prefixing the country code with a plus sign (+), which also indicates to the subscriber that the local international call prefix must first be dialed. For example, the international call prefix in all countries of the North American Numbering Plan is 011, while it is 00 in mo ...

FinFisher
FinFisher, also known as FinSpy, is surveillance software marketed by Lench IT Solutions plc, which markets the spyware through law enforcement channels. FinFisher can be covertly installed on targets' computers by exploiting security lapses in the update procedures of non-suspect software. The company has been criticized by human rights organizations for selling these capabilities to repressive or non-democratic states known for monitoring and imprisoning political dissidents. Egyptian dissidents who ransacked the offices of Egypt's secret police following the overthrow of Egyptian President Hosni Mubarak reported that they had discovered a contract with Gamma International for €287,000 for a license to run the FinFisher software. In 2014, an American citizen sued the Ethiopian government for surreptitiously installing FinSpy onto his computer in America and using it to wiretap his private Skype calls and monitor his entire family's every use of the computer for a period ...

Trojan Horse (computing)
In computing, a Trojan horse is any malware that misleads users of its true intent. The term is derived from the Ancient Greek story of the deceptive Trojan Horse that led to the fall of the city of Troy. Trojans generally spread by some form of social engineering; for example, where a user is duped into executing an email attachment disguised to appear innocuous (e.g., a routine form to be filled in), or by clicking on some fake advertisement on social media or anywhere else. Although their payload can be anything, many modern forms act as a backdoor, contacting a controller who can then have unauthorized access to the affected computer. Ransomware attacks are often carried out using a Trojan. Unlike computer viruses and worms, Trojans generally do not attempt to inject themselves into other files or otherwise propagate themselves. Use of the term It's not clear where or when the concept, and this term for it, was first used, but by 1971 the first Unix manual assume ...

Telephony
Telephony ( ) is the field of technology involving the development, application, and deployment of telecommunication services for the purpose of electronic transmission of voice, fax, or data, between distant parties. The history of telephony is intimately linked to the invention and development of the telephone. Telephony is commonly referred to as the construction or operation of telephones and telephonic systems and as a system of telecommunications in which telephonic equipment is employed in the transmission of speech or other sound between points, with or without the use of wires. The term is also used frequently to refer to computer hardware, software, and computer network systems, that perform functions traditionally performed by telephone equipment. In this context the technology is specifically referred to as Internet telephony, or voice over Internet Protocol (VoIP). Overview The first telephones were connected directly in pairs. Each user had a separate telephone wire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telephone Numbers
A telephone number is a sequence of digits assigned to a landline telephone subscriber station connected to a telephone line or to a wireless electronic telephony device, such as a radio telephone or a mobile telephone, or to other devices for data transmission via the public switched telephone network (PSTN) or other public and private networks. A telephone number serves as an address for switching telephone calls using a system of destination code routing. Telephone numbers are entered or dialed by a calling party on the originating telephone set, which transmits the sequence of digits in the process of signaling to a telephone exchange. The exchange completes the call either to another locally connected subscriber or via the PSTN to the called party. Telephone numbers are assigned within the framework of a national or regional telephone numbering plan to subscribers by telephone service operators, which may be commercial entities, state-controlled administrations, or ...
