With the existing Public Switched Telephone Network ( PSTN ), Lawful Interception (LI) is performed by applying a 'tap' on the telephone line of the target in response to a warrant from a Law Enforcement Agency (LEA). However, Voice Over IP (VoIP) technology has enabled the mobility of the end-user, so it is no longer possible to guarantee the interception of calls based on tapping a physical line. Whilst the detailed requirements for LI differ from one jurisdiction to another, the general requirements are the same. The LI system must provide transparent interception of specified traffic only, and the subject must not be aware of the interception. The service provided to other users must not be affected during interception. EXTERNAL LINKS |
