Lawful interception is the process by which law enforcement agencies conduct electronic surveillance of circuit and packet-mode communications, authorized by judicial or administrative order. Vox LI proposes a monitoring architecture for lawful interception on VoIP networks based on SIP.
This is a user interface with role-based access controls to manage intercept information. All the call monitoring information can be accessed from here.
It contains a core software application with real-time processing mechanism to filter calls as per the origination/termination by subscriber or agent.
This does the routing, identification, encapsulation, and delivery of content in real-time and can be recorded and saved in Lawful Interception server, if required.
