False Answer Supervision
These include: * False billing of party A without calling a party B. Usually a fake ringback tone, loopback audio or voicemail message is played * Start of billing before actual answer of party B * Extra billing after disconnection of party B Detection of FAS The FAS can be detected and blocked in a softswitch. Common methods are: * Manual verification of call detail records: listening to voice recordings * Identification of FAS types and using algorithms to automatically detect the FAS ** RTP audio signal processing: detection of voice ** RTP audio signal processing: detection of silence ** RTP audio signal processing: detection of ringback tone See also *Phone fraud *Softswitch *Telecommunications billing *Voice over IP Voice over Internet Protocol (VoIP), also known as IP telephony, is a set of technologies used primarily for voice communication sessions over Internet Protocol (IP) networks, such as the Internet.

VoIP
Voice over Internet Protocol (VoIP), also known as IP telephony, is a set of technologies used primarily for voice communication sessions over Internet Protocol (IP) networks, such as the Internet. VoIP enables voice calls to be transmitted as data packets, facilitating various methods of voice communication, including traditional applications like Skype, Microsoft Teams, Google Voice, and VoIP phones. Regular telephones can also be used for VoIP by connecting them to the Internet via analog telephone adapters (ATAs), which convert traditional telephone signals into digital data packets that can be transmitted over IP networks. The broader terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the delivery of voice and other communication services, such as fax, SMS, and voice messaging, over the Internet, in contrast to the traditional public switched telephone network (PSTN), commonly known as plain old telephone service (POTS) ...

Softswitch
A softswitch (''software switch'') is a call-switching node in a telecommunications network, based not on the specialized switching hardware of the traditional telephone exchange, but implemented in software running on a general-purpose computing platform. Like its traditional counterparts it connects telephone calls between subscribers or other switching systems across a telecommunication network. Often a softswitch is implemented to switch calls using voice over IP (VoIP) technologies, but hybrid systems exist. Although the term ''softswitch'' technically refers to any such device, it is conventionally applied to a device that handles IP-to- IP phone calls, while the phrase '' access server'' or "media gateway" is used to refer to devices that either originate or terminate traditional land line phone calls. In practice, such devices can often do both. An access server might take a mobile call or a call originating from a traditional telephone line, convert it to IP traffic, the ...

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 Switchboard operator, operators for long-distance calls in a telephone switchboard, manual telephone exchange. CDR contents A call detail record contains Field (computer science), 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 durati ...

Phone 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: * $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 by t ...

Telecommunications Billing
Telecommunications billing is the group of processes of communications service providers that are responsible to collect consumption data, calculate charging and billing information, produce bills to customers, process their payments and manage debt collection. A telecommunications billing system is an enterprise application software designed to support the telecommunications billing processes. Telecommunications billing is a significant component of any commercial communications service provider regardless specialization: telephone, mobile wireless communication, VoIP companies, mobile virtual network operators, internet service providers, transit traffic companies, cable television and satellite TV companies could not operate without billing, because it creates an economic value of their business. Telecommunications billing functions Billing functions can be grouped to three areas: operations, information management, financial management. In the broad sense, when ''billin ...

Telecommunications
Telecommunication, often used in its plural form or abbreviated as telecom, is the transmission of information over a distance using electronic means, typically through cables, radio waves, or other communication technologies. These means of transmission may be divided into communication channels for multiplexing, allowing for a single medium to transmit several concurrent Session (computer science), communication sessions. Long-distance technologies invented during the 20th and 21st centuries generally use electric power, and include the electrical telegraph, telegraph, telephone, television, and radio. Early telecommunication networks used metal wires as the medium for transmitting signals. These networks were used for telegraphy and telephony for many decades. In the first decade of the 20th century, a revolution in wireless communication began with breakthroughs including those made in radio communications by Guglielmo Marconi, who won the 1909 Nobel Prize in Physics.
