Yealink CM20

The CM20 is Yealink's ceiling microphone within the Audio Conference range, confirmed as the microphone component bundled inside the Yealink CMKit-121 room kit ("1 x CM20 Ceiling Microphone"). As a standalone listing, the manufacturer currently publishes only a specification-label index — Microphone Array, Pickup Zones, Coverage Radius, Beamforming Technology, AI Noise Reduction, AI Reverberation Suppression, Integrated DSP and Frequency Response among them — without corresponding values or description text.

The labelled categories indicate a multi-zone beamforming ceiling array with plug-and-play deployment, colour and mounting options, and platform compatibility for conferencing systems, consistent with its role inside the CMKit-121 bundle.
