Multi Attendee Video Conferencing - Unusable Quality
Hi Bradley Wood ,
It sounds very much to me that there are some network components getting in the way of Teams traffic. In a 1:1 call the data can be sent direct if the two parties are on the same network, but as soon as a third is added all need to connect via Microsoft.
The defined requirement for Teams is that the clients can send UDP traffic on ports 3478-3481 directly to the internet, if this is blocked it will use TCP 443 https as a fallback, but the quality is far worse. If that's also being forced through a proxy server, then it'll be even worse again. If remote users are forced to use a VPN then all this will apply to them, again it's recommended that they have split tunneling so can send their Teams traffic directly.
Here's the documentation about Teams networking https://docs.microsoft.com/en-us/microsoftteams/prepare-network
StevenC365 Hey Steven, great post! But what got my attention was the "This has actually been the case for the entire past couple of months (the covid months)".
ChristianBergstrom - thanks to both of you for your comments. I should have mentioned, we've only been using Teams this past couple months, so we have no positive experience in prior months. I can see how increased use would cause some issues
StevenC365 We aren't forcing people through VPN's, so that isn't a factor. I'm at home and I've had 1:1 meetings with others at home, and others on premise. However whenever we add a third, it is always including someone on premise. An interesting component to investigate a bit further. The firewall comments were useful, we will look into that.
Thanks
- FYI Bradley, our issues started a couple of months ago (covid). Before that the experience where pretty much flawless. We all work from home with direct connection to the internet (no vpn involved).
