This course will provide the student with a set of analysis techniques focusing on the use of vendor-neutral, Open-Source Tools to provide insight into the following areas:

  • VoIP, Video over IP, T.120 Conference and T.38 Fax over IP Network
    Analysis fundamentals
  • VoIP focused network security principles including encryption
    technologies and defensive configurations of network infrastructure devices
  • Recognition for a variety of issues that affect VoIP and
    Video-based networks and the quality of the voice data. Factors including,
    latency, out-of-sequence packets, Jitter and Quality-of-Service and how the
    End-User experiences them will be analyzed and evaluated.  Key VoIP
    related protocols including SIP, MGCP, SCCP, UNISTEM, H.323, T.38 T.120 and
    related supporting protocol architectures will be examined.
  • Open-Source VoIP, Video and T.38 Network Analysis Tools
  • Specialized VoIP, Video and Fax over IP Network Analysis
    techniques including audio / Video data traffic reconstruction and viewing
    techniques.

This course is designed for Networking, Government and Security personnel that need to develop a set of packet investigation techniques through study of the Voice, Video and Multimedia over IP-based Protocols using Wireshark and other Open-Source Analysis tools. Successful completion of this course will provide these individuals with a path-way into the field of Multimedia over IP-based Analysis.
