CALEA and VOIP

Introduction
CALEA: Communications Assistance Law Enforcement Agency
In response to concerns that emerging technologies such as digital and wireless communications were making it increasingly difficult for law enforcement agencies to execute authorized surveillance, Congress enacted CALEA on October 25, 1994. CALEA was intended to preserve the ability of law enforcement agencies to conduct electronic surveillance by requiring that telecommunications carriers and manufacturers of telecommunications equipment modify and design their equipment, facilities, and services to ensure that they have the necessary surveillance capabilities. Common carriers, facilities-based broadband Internet access providers, and providers of interconnected Voice over Internet Protocol (VoIP) service - all three types of entities are defined to be "telecommunications carriers" for purposes of CALEA section 102, 47 U.S.C. § 1001 - must comply with the CALEA obligations set forth in CALEA section 103, 47 U.S.C. § 1002
LI (lawful intercept) solution overview
Lawful Interception (LI) is the interception of telecommunications performed by law enforcement agencies (LEA) based on national legislation to help LEA to combat against criminal activities. All interceptions must have proper authorization from competent authorities.

Based on the service types, interception falls into Intercept Related Information (IRI) interception and Content of Communication (CC) interception. The Intercept Related Information refers to signal information about the target communications, including destination of a voice call (for example, called telephone number), source of a call (calling phone number), time of the call, duration, and so on. Content of Communication is namely the voice, email content or message content.
