• Zoom's own documentation disagrees on the audio DSCP. The Support KB lists 56 as the default, while the Technical Library's 4-class model table lists EF (46) among the 'common Zoom DSCP values' for audio. disputed in context
• Zoom states that enabling DSCP marking through the web portal or Group Policy marks only packets outbound from Zoom apps, so network devices must tag inbound traffic. in context
• Zoom states that its outbound DSCP tags must be trusted by the computers and network components on the path to stay intact, and that tags can be stripped when traversing the Internet. in context
• Zoom warns that DSCP tags may not be recognised by other internal network components and can be stripped when traversing the Internet. in context
• Enabling Zoom DSCP marking through the web portal or Group Policy marks only packets outbound from Zoom apps; inbound prioritisation needs network-side tagging on firewalls and routers. in context
• When DSCP marking is enabled in the Zoom web portal, Zoom Workplace desktop and mobile apps version 6.0 or later and supported Cisco, Poly and Yealink IP phones mark Zoom Phone audio packets. in context
