I’ve had a few friends working from home asking about how to improve their Zoom conferences, and before I point them at OpenWRT as an option, I wanted to verify that there is a straightforward path to achieving improvements without getting to down in the weeds.
My first though is that Cake with Diffserv4 as QoS should be all they need to configure and be set, but not sure if that is indeed all that’s needed, as it seems from the DSCP code points the Zoom App sets (56 for audio, 40 for video, and 40 for signaling), that all traffic would wind up in the (bandwidth limited) VoIP tier.

Anyone use Zoom + Cake and can confirm if traffic winds up in the expected tins?
