Call Logging
Call logging is the collection, evaluation, and reporting of technical and statistical data about telephone calls. It does not encompass phone tapping or call recording. Collecting data Telephone call data, such as originating station, destination, start and ending times, and transmission characteristics, is collected from a telecommunications system or private branch exchange (PBX) in form of call detail records (CDRs). The equipment typically presents this data on older PBXs via a serial communications port, or more recently via a computer network over an Ethernet connection. From the interface, CDRs are collected on computer systems running call logging and analysis software. Some PBX manufacturers provide their own basic call logging software but many other third-party software packages are available. Call logging software The goal of the call logging software is to interpret the raw CDR data and produce graphical and summarizing reports. Call logging software packages differ ...

Telephone Call
A telephone call is a connection over a telephone network between the called party and the calling party. First telephone call The first telephone call was made on March 10, 1876, by Alexander Graham Bell. Bell demonstrated his ability to "talk with electricity" by transmitting a call to his assistant, Thomas Watson. The first words transmitted were "Mr Watson, come here. I want to see you." This event has been called Bell's "greatest success", as it demonstrated the first successful use of the telephone. Although it was his greatest success, he refused to have a telephone in his own home because it was something he invented by mistake and saw it as a distraction from his main studies. Information transmission A telephone call may carry ordinary voice transmission using a telephone, data transmission when the calling party and called party are using modems, or facsimile transmission when they are using fax machines. The call may use land line, mobile phone, satellit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Telephone Tapping
Telephone tapping (also wire tapping or wiretapping in American English) is the monitoring of telephone and Internet-based conversations by a third party, often by covert means. The wire tap received its name because, historically, the monitoring connection was an actual electrical tap on the telephone line. Legal wiretapping by a government agency is also called lawful interception. Passive wiretapping monitors or records the traffic, while active wiretapping alters or otherwise affects it. Legal status Lawful interception is officially strictly controlled in many countries to safeguard privacy; this is the case in all liberal democracies. In theory, telephone tapping often needs to be authorized by a court, and is again in theory, normally only approved when evidence shows it is not possible to detect criminal or subversive activity in less intrusive ways. Oftentimes, the law and regulations require that the crime investigated must be at least of a certain severity. Ille ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Call-recording Software
Mp3/3gpp/wavCall recording software records telephone conversations over PSTN or VoIP in a digital audio file format. Call recording is distinct from call logging and tracking, which record details about the call but not the conversation; however, software may include both recording and logging functionality. Considerations Call recording is becoming increasingly important, with technology changing and working habits becoming more mobile. Addressing mobile recording is now the subject of many financial regulators' recommendations. It is also increasingly important to business continuity planning, especially for pandemic planning. The actual recording takes place on a recording system with software for the management of calls and security of recordings. Most call recording software applications rely on an analogue signal via either a call recording adapter or a telephony board. Digital lines cannot be recorded unless the call recording system can capture and decode the proprietary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Telecommunication
Telecommunication is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems (such as postal mail) are excluded from the field. The transmission media in telecommunication have evolved through numerous stages of technology, from beacons and other visual signals (such as smoke signals, semaphore telegraphs, signal flags, and optical heliographs), to electrical cable and electromagnetic radiation, including light. Such transmission paths are often divided into communication channels, which afford the advantages of multiplexing multiple concurrent communication sessions. ''Telecommunication'' is often used in its plural form. Other examples of pre-modern long-distance communication included audio messages, such as code ...

Private Branch Exchange
A business telephone system is a multiline telephone system typically used in business environments, encompassing systems ranging in 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 related to call handling. Business telephone systems are often broadly classified into key telephone systems, and private branch exchanges, but many hybrid 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 the switchboard to establish connections between the central office trunks and stations, or between stations. Technologically, private branch exchanges share lineage with centra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Call Detail Record
A call detail record (CDR) is a data record produced by a telephone exchange or other telecommunications equipment that documents the details of a telephone call or other telecommunications transactions (e.g., text message) that passes through that facility or device. The record contains various attributes of the call, such as time, duration, completion status, source number, and destination number. It is the automated equivalent of the paper toll tickets that were written and timed by operators for long-distance calls in a manual telephone exchange. CDR contents A call detail record contains data fields that describe a specific instance of a telecommunication transaction, but does not include the content of that transaction. By way of simplistic example, a call detail record describing a particular phone call might include the phone numbers of both the calling and receiving parties, the start time, and duration of that call. In actual modern practice, call detail records are m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Telephone Fraud
Phone fraud, or more generally communications fraud, is the use of telecommunications products or services with the intention of illegally acquiring money from, or failing to pay, a telecommunication company or its customers. Many operators have increased measures to minimize fraud and reduce their losses. Communications operators tend to keep their actual loss figures and plans for corrective measures confidential. According to a 2011 survey by CFCA, an industry group created to reduce fraud against carriers, the five top fraud loss categories reported by operators were: * US$4.96 billion – compromised PBX/voicemail systems * $4.32 billion – subscription/identity theft * $3.84 billion – International Revenue Share Fraud * $2.88 billion – by-pass fraud * $2.40 billion – cash fraud Types of frauds Fraud against users by phone companies * '' Cramming'' is the addition of charges to a subscriber's telephone bill for services which were neither ordered nor desired b ...

VoIP
Voice over Internet Protocol (VoIP), also called IP telephony, is a method and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. The terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the Internet, rather than via the public switched telephone network (PSTN), also known as plain old telephone service (POTS). Overview The steps and principles involved in originating VoIP telephone calls are similar to traditional digital telephony and involve signaling, channel setup, digitization of the analog voice signals, and encoding. Instead of being transmitted over a circuit-switched network, the digital information is packetized and transmission occurs as IP packets over a packet-switched network. They transport media streams using special media delivery proto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Quality Of Service
Quality of service (QoS) is the description or measurement of the overall performance of a service, such as a telephony or computer network, or a cloud computing service, particularly the performance seen by the users of the network. To quantitatively measure quality of service, several related aspects of the network service are often considered, such as packet loss, bit rate, throughput, transmission delay, availability, jitter, etc. In the field of computer networking and other packet-switched telecommunication networks, quality of service refers to traffic prioritization and resource reservation control mechanisms rather than the achieved service quality. Quality of service is the ability to provide different priorities to different applications, users, or data flows, or to guarantee a certain level of performance to a data flow. Quality of service is particularly important for the transport of traffic with special requirements. In particular, developers have introduced ...

Director Telephone System
The director telephone system was a development of the Strowger or step-by-step (SXS) switching system used in London and five other large cities in the UK from the 1920s to the 1980s. A large proportion (c. 70% to 80%) of telephone traffic in large metropolitan areas is outgoing traffic, and it is distributed over many exchanges. A non-director SXS exchange system is not suitable for these areas. As the translation facility incorporated was similar to the register in common control systems, the director system incorporates two features of the Panel system, which was introduced in large American cities, and which were required regardless of the type of exchange system for these large areas, which would have a mixture of manual and automatic exchanges for some years. Customer stations were assigned seven-digit numbers, with the first three digits spelling out the local exchange name; this expedited call handling particularly to and from manual exchanges. Direct or tandem juncti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Call Management
Call management is the process of designing and implementing inbound telephone call parameters, which govern the routing of these calls through a network. The process is most prominently utilized by corporations and the call centre industry and has its highest effectiveness when call logging software tools are used. Calls are routed according to the set up of calling features within the given system such as Call queues, IVR menus, Hunt groups and Recorded announcements. Call features provide a customised experience for the caller and maximize the efficiency of inbound call handling. Call management parameters can specify how calls are distributed according to an operator's skill level in relation to a call, the time and/or date of a call, the location of the caller or through automatic routing processes. Calling features Call management features vary from system to system and are based on an organization's needs to enhance customer experience. The systems commonly retain inform ...

Call-tracking Software
Call tracking software records information about incoming telephone calls, and in some regions even the conversation. Call tracking is a technology which can enable the pay per call, pay per minute or pay per lead business model, allowing the tracking of phone calls to be associated with performance-based advertising such as Google AdWords, SEO Services, Display and Electronic Direct Marketing, and supplying additional analytic information about the phone calls themselves. Call tracking is a method of performance review for advertising and/or staff. It is based on the technological possibility of measuring the behavior of callers and is thus the equivalent in telephony to the conversion tracking used on the internet. Via different channels, both procedures offer the opportunity of clearly assigning a customer response to a specific advertising medium. Methods There are currently four technological methods for telephone tracking. Besides an exclusively web-based function, it is ...
