Outgoing Camera feed drops on Teams
henry_good I would look up one of the attendees of the meeting and find the meeting under Meetings and Calls, if you poke around the data you will typically find when the video stream started and stopped and any likely reason for it happening.
I guess it'll either be related to the device (if it's not Teams certified) or network (e.g. a proxy/firewall ending a session)/
StevenC365We have had similar issues where packet inspection on the traffic through the firewall has been the cause. The video stream and audio stream are different connections and video is more vulnerable to being delayed or dropped, especially when you start working in 4K conferencing systems.
In the end we had to white-list the video stream separate to the audio stream (possibly a Fortigate specific glitch). Check your filtering of UDP 50020-50039, and port 443 to *.teams.microsoft.com
