Microsoft Teams Traffic on SD-WAN, Explained. Troubleshooting in detail

Описание: Microsoft Teams Traffic on SD-WAN Explained | End-to-End Flow & Troubleshooting

In this video, we deep-dive into how Microsoft Teams traffic behaves on SD-WAN networks and how to troubleshoot common call quality issues step by step.

Microsoft Teams is a real-time collaboration application, and its audio, video, and screen-sharing traffic is highly sensitive to latency, jitter, and packet loss. A small SD-WAN misconfiguration can result in choppy audio, frozen video, or call drops.

🔹 What You’ll Learn in This Video

✔ Types of Microsoft Teams traffic (Signaling, Media, Content)
✔ How Teams traffic flows through SD-WAN
✔ Why UDP media traffic needs priority
✔ Local Internet Breakout vs Backhauling
✔ Application-Aware Routing (AAR) for Teams
✔ QoS, DSCP marking, and WAN queue design
✔ Real-world troubleshooting scenarios

🔹 Microsoft Teams Traffic Types Explained

🔸 Signaling Traffic – Login, chat, call setup (TCP 443)
🔸 Media Traffic – Audio, video, screen share (UDP, real-time)
🔸 Content Traffic – File sharing & downloads (TCP 443)

👉 Media traffic is the most critical and must always be prioritized on SD-WAN.

🔹 SD-WAN Best Practices for Teams

✅ Local Internet Breakout (DIA)
✅ Prefer best-quality WAN path using SLA
✅ Strict priority QoS for real-time media
✅ Preserve DSCP markings end-to-end
✅ Avoid unnecessary data-center hair-pinning

🛠️ Troubleshooting Covered in Detail

🔧 Teams traffic not classified correctly
🔧 Poor audio or robotic voice
🔧 Video freezing or lag
🔧 One-way audio issues
🔧 DSCP remarking problems
🔧 Firewall, NAT, and ALG issues
🔧 SD-WAN path steering errors

🚨 Common Symptoms & Root Causes

❌ Choppy audio → High jitter / packet loss
❌ Call drops → Path flapping or NAT timeout
❌ One-way audio → Firewall or SIP ALG
❌ Video lag → Bandwidth congestion
