QoS and DSCP for Zoom

[broonster]

Hi There,

This poorly written Zoom KB https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0066617 on QoS for Zoom states that to force the client to use different ports for audio, video and screen sharing you need to set “EnableIndependentDataPort”=dword:00000001 in the registry.

However in the section below describing how to configure a Group Policy is doesn't mention any port numbers at all and only shows how to configure DSCP markings for all traffic coming from the zoom.exe.

So I have a couple of questions:
1. If I set “EnableIndependentDataPort”=dword:00000001 what are the port numbers used for audio, video and screen sharing?
2. Does “EnableIndependentDataPort”=dword:00000001  work on the "free" version of Zoom that individuals install manually themselves? I think this might be termed the .exe installer.
