Zoom meetings severe real-time traffic impairment (packet loss > 80%, > 9 second latency) - screenshare unusable

Agent finally was willing to log a support ticket 

CUIxxxxxxxx54 yesterday, after lengthy discussion of problem I've had for over a year. Not to disparage that agent, but I honestly don't have a lot of confidence that Cox engineering team will investigate.

I have a (lousy) workaround, that allows me to limp by using corporate VPN to bypass Cox routing to Zoom.

In other words, unusable with Cox-only, but problems immediately disappear when I bypass Cox routing/peering.

Curious if any other frequent Zoom users (I'm in Phoenix area) have similar issues?

I have a bunch of geeky details if anyone is interested (e.g., netstat -an output, screenshots from Zoom diagnostics, etc.).

I've taken several steps to narrow the culprit to Cox:

• tested Zoom with multiple laptops (Mac and Windows)
• tested with direct connection to Fiber ONT (eliminating my Router)

Thanks!
