Lawful Interception (LI) is the process by which targeted communications traffic is intercepted for delivery to a law enforcement agency (LEA) based on a warrant or court order.
VOCAL’s Lawful Interception software provides extraction and processing of data from recorded network traffic or real-time data streams. Our expertise with VoIP, T.38 and other network protocols is essential for extracting the data of interest from the large volumes of network traffic that can be collected. With these capabilities, developers have a range of lawful interception solutions to monitor, intercept, and decode voice, video, fax and data transmissions. Our Lawful Interception software extracts:
- VoIP data to audio and/or video files.
- T.38 Fax data to image files.
- Fax data to image files from both standard and T.30 NSF fax machines.
VOCAL has substantial experience with recording technologies and can help advise in the proper configuration of your recording system. For important recordings with insufficient signal quality or damage, VOCAL can also provide analysis and manual inspection services which may be able to recover some or all of the relevant data.
