A recent update enables tenant admins to modify the DSCP (Differentiated Services Code Point) value of voice traffic to enable Quality of Service (QoS).


How to Configure Voice Quality of Service

The VoiceDiffServTag represents the DSCP value assigned to voice traffic in Skype for Business. To modify this setting, run the Set-CsUCPhoneConfiguration via Remote PowerShell and set it to desired value. It is recommended that voice traffic be marked with a DSCP value of 46.
