Why this is useful
Compares an intact RTP capture with a copy containing deliberately removed packets. The stream list and detailed analysis show how gaps become loss indicators and how burst patterns differ from scattered loss.
Applicability
Concepts still applicableA 2024 Wireshark demonstration; menu placement can change. The second capture is a teaching fixture with simulated loss.
Keep in mind
- A gap at one capture point can reflect capture loss or reordering. Compare SSRCs, both directions and paired capture points before assigning a network fault.
- RTP sequence numbers do not universally begin at one and eventually wrap. Correlate streams with SDP rather than port numbers alone.
- Protect packet captures and call audio. Do not post production traces in public comments.
