Does Genesys Cloud support QoS for WebRTC phones?

No. Genesys Cloud does not natively provide QoS for WebRTC phones. Instead, Genesys Cloud provides you with the Mean Opinion Score (MOS), which is a measurement of the voice quality of an interaction. To calculate MOS, Genesys Cloud uses an industry standard measurement methodology to rank audio quality from 1 (unacceptable) to 5 (excellent). You can view the MOS values in the Interactions view. For more information, see Mean Opinion Score (MOS) Overview and Interactions view.
