Were you aware that during the 20th Century, POTS (plain old telephone service) became the central form of communications? Well, to help law enforcement agencies (LEAs) do their job safely and effectively, a method called “wiretapping” was developed to lawfully monitor and collect telephone communications of alleged criminals once a warrant was granted from the judicial system. It was called wire tapping as the observing and connection device was an authentic electric tap on the telephone route.
What does a Wiretap system mean?
A Wiretap system, also known as Telephone tapping or wiretapping refers to the method of observing or monitoring cellphone and Internet-based conversations via 3rd party often by covert channels.
How do Wiretap Systems work?
Operating through the proficiencies in telecommunications and cellphone networks, Lawful interception (LI) permits LEA’s with court directives or various other legal sanctions to specifically wiretap discrete targets.
The surveillance is performed using wiretap systems on traditional telecommunications and Internet services in voice, data, and multiservice networks. The LEA delivers a request for a wiretap system to the target’s service provider, who is responsible for intercepting data communication to and from the individual.
Stratign’s Monitoring Centre (STN-MC) – A perfect solution for Lawful Interception
The LI system solution from Stratign is a switch-oriented Lawful Interception System which is proficient of seizing targeted communications from Telecom Switches. This nationwide phone interception solution can intercept all communications (mobile and fixed line) which are going through the telecom switches.
The Stratign Monitoring Centre (STN-MC) is a turnkey solution for the monitoring, processing, decoding distribution and presentation of intercepted data of targets from circuit switched networks. (for example, handset and fixed telephony) as well as for packet switched systems (e.g. internet, email) and is used by law enforcement and/or intelligence agencies. The STN MC is compliant with the latest ETSI and/or CALEA specifications for the Lawful Interception System but can also support country specific LI handover protocols.
