Voice handsets on a courthouse SSID show choppy calls, and QoS data frames in the capture are marked Best Effort instead of Voice. What should be verified?
Select an answer to reveal the explanation.
Short Explanation
If courtroom voice packets wear the 'ordinary mail' Best Effort sticker instead of the 'priority' Voice sticker, they wait in the slow line even when the radio is loud and clear. Check the WMM access category on the QoS data frames.
Full Explanation
WMM maps traffic to access categories (VO, VI, BE, BK) with different EDCA parameters. Voice marked as Best Effort contends with ordinary data and loses latency guarantees. Capture inspection of QoS Control / UP markings verifies whether client and SSID policy correctly classify voice as AC_VO.
