I don’t know if this is applicable, bur for zoom and teams we were seeing issues where as more people joined there would be poor audio or lag. Zoom does start off using TCP, but under load it will also use additional UDP ports, we found that by permitting UDP 3478-3481 for both Teams and Zoom we saw a noticeable improvement We were previously allowing just UDP8801-8810 and TCP8801-8802

Also, go have a look at the events for the AP's in question. We had a few reports of call pauses/lags, and with the Zoom diagnostic data from the meeting details in-hand, we correlated it to the client's connected AP switching channels because of RRM/Interference. If you're not familiar with the Zoom client/meeting data, ask your Zoom admin to give you access to the dashboard. For live and past meetings you can see a wealth of information on what the client is up to and how it is performing.

Most of the complaints have been around multiple drops during calls or lagging calls. Our res halls are currently only at 40-50% capacity if that. I was curious if anyone else has been seeing any issues with an increase of Zoom calls from on campus students. -- Charles Rumford (he/his/him) IT Architect ISC Tech Services University of Pennsylvania OpenPGP Key ID: 0xF3D8215A ********** Replies to EDUCAUSE Community Group emails are sent to the entire community list.
