Hello Ana,
With regards to a MOS of 4.4, that is a pretty good score. If you are using the g711 codec, the maximum MOS will be 4.4. I believe that using opus will be your best bet if you are trying to improve that number. But I will caveat that with the following: Genesys Cloud uses the lowest MOS for the interaction's score. So be warned that the MOS can look low if the callers audio quality is less than ideal.
