Force all Teams Voice traffic out WAN2 and prioritize over other traffic

[nflnetwork29]

Hello,

We’re running a standalone FortiGate 60F on FortiOS 7.4.7. Our setup has two WAN links:

• ISP1 = backup

• ISP2 = primary

Our goal is to:

1. Force all Microsoft Teams voice/media traffic (UDP 3478–3481 for STUN/TURN and UDP 50000–50059 for RTP) to always use ISP2, with ISP1 only as a backup.

2. Make sure Teams voice traffic has higher priority than all other traffic on the network so call quality isn’t impacted during congestion.

Since this is a standalone 60F, I know some advanced SD-WAN features may not be available. What’s the best practice on this platform for:

• Steering those specific ports to ISP2 (router-policy vs SD-WAN service match).

• Ensuring return traffic stays symmetric on ISP2.

• Setting QoS / traffic shaping so Teams traffic gets top priority.

Any config snippets or guidance would be appreciated!

Thanks,
