Abstract
Summary:
- 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.
