Understanding SIP Traces and Debug Logs

• The session reviews SIP request/response flow, identifying key call setup, teardown, and SDP messaging patterns.
• Demonstrates capturing traces using Wireshark, CUCM RTMT, and TranslatorX to derive detailed call path data.

ChatGPT–Enhanced Analysis

• Highlights how to prompt ChatGPT effectively with SIP trace snippets to decode complex protocol operations.
• Showcases ChatGPT’s ability to automatically flag errors (e.g., 403 Forbidden, missing SDP) and propose corrective actions.
• Emphasizes maintaining structured context (timestamps, call IDs) in prompts for accurate AI-assisted analysis.

Troubleshooting Common SIP Issues

• Identifies frequently seen problems: one-way audio, registration failures, SIP header mismatches, and codec negotiation conflicts.
• Demonstrates how AI can pinpoint root causes and suggest actionable fixes more efficiently than manual parsing.

SIP Troubleshooting Tools

Walks through tools like:

• Wireshark: filtering and interpreting SIP packets
• CUCM RTMT: real-time call trace monitoring
• TranslatorX: translating debug logs into readable formats
• CUBE DNA and Collaboration Analyzer: enriched SIP analysis.

Workflow Integration and Best Practices

• Encourages combining AI with traditional tools in a hybrid troubleshooting workflow—capture logs, query ChatGPT, verify insights, and implement fixes.
• Highlights benefits of structured prompting, including specifying line context, entire call IDs, and relevant metadata for AI accuracy.

Efficiency Gains and Professional Impact

• AI assistance reduces time-to-resolution, cuts down on manual trace interpretation, and lowers the learning curve for junior engineers.
• Empowers teams to scale troubleshooting capabilities, share AI-enabled debug patterns, and build repeatable analysis templates.

Final Takeaway

• Capture SIP debug logs via Wireshark, RTMT, and TranslatorX.
• Use structured prompts to feed traces into ChatGPT.
• Let AI interpret errors and suggest preventive or corrective steps.
• Validate results and apply fixes via CUCM, CUBE, or PSTN settings.
• Wrap the solution into a hybrid workflow that streamlines SIP troubleshooting across teams.
