  • Understanding the network function of an object can help you understand observer flow data.
    • Many comment elements between VoIP deployments (Proxy, Redirect, Voice Mail, Transcoder, etc.)
  • Their two use cases for real-time communication:
    • On-demand generation - noise = packets
    • Software generated packets - endless packets
  • Data Exfiltration
    • Unidirectional flow, unless software-generated packets.
    • Weak Compression will create long flows.
    • On-demand VoIP will look like SW VoIP.
