Oracle SBC Troubleshooting, Operations and Maintenance (OCI) Ed 1 — Lesson 3: Media, NAT, Codecs, DTMF, One-Way Audio, Quality, and Security Diagnostics

Learning Objectives

• Interpret prerequisites, ownership, dependencies, and failure conditions for media, nat, codecs, dtmf, one-way audio, quality, and security diagnostics.
• Perform the course-specific workflow while recording evidence at each material checkpoint.
• Prove the solution against security, control, reliability, performance, and support criteria.

Detailed Topics

• Media
• NAT
• Codecs
• DTMF
• One-Way Audio
• Quality
• ownership, prerequisites, data, and acceptance criteria for media, nat, codecs, dtmf, one-way audio, quality, and security diagnostics
• security, control, integration, performance, recovery, and support implications

Instructor Demonstration

Demonstrate media, nat, codecs, dtmf, one-way audio, quality, and security diagnostics within an OCI SBC operations team diagnosing failed calls, media defects, signaling errors, and HA incidents without causing service disruption. Use representative data and capture HMR output, media statistics so another practitioner can verify the result.

Hands-On Exercise

Complete a controlled Oracle SBC Troubleshooting, Operations and Maintenance (OCI) Ed 1 activity focused on media, nat, codecs, dtmf, one-way audio, quality, and security diagnostics. Introduce a realistic case of one-way audio, isolate its cause, apply a reversible correction, and rerun the acceptance checks.

1. Record the requirement, environment, identities, dependencies, data, controls, and expected result.
2. Perform the workflow and capture course-specific evidence before and after each material change.
3. Test normal, boundary, failure, security, reconciliation, recovery, and operational conditions.
4. Document the root cause, correction, rollback, owner, support action, and next improvement priority.

Scenario Analysis

• Establish current state, desired state, constraints, and acceptable service impact.
• Compare alternative implementation or diagnostic approaches and their rollback consequences.
• Document the decision, evidence, exception, corrective action, and measurable improvement target.

Troubleshooting Guidance

When media, nat, codecs, dtmf, one-way audio, quality, and security diagnostics does not produce the expected result, confirm scope, effective dates, identities, data context, dependencies, and recent changes. Review the most relevant HMR output, media statistics before editing configuration. Test one reversible hypothesis at a time, verify recovery, and confirm that the fix does not create one-way audio elsewhere.

Validation Checklist

• Prerequisites, ownership, data context, settings, and expected outcomes are documented.
• The result is reproducible and supported by HMR output, media statistics.
• Security, controls, data quality, integration, performance, recovery, and support conditions are reviewed.
• Exceptions, corrective action, rollback, approvals, monitoring, and handover are recorded.

Lesson Outcome

Learners can apply Media, NAT, Codecs, DTMF, One-Way Audio, Quality, and Security Diagnostics in a realistic Oracle SBC Troubleshooting, Operations and Maintenance (OCI) Ed 1 situation and defend the result with course-specific evidence.
