Technical Introduction:
Lawful Interception (LI) is a requirement placed upon service providers to provide legally sanctioned official access to private communications. With the existing Public Switched Telephone Network (PSTN), Lawful Intercept is performed by applying a physical '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.
