Call quality issues with Teams

We just moved to Teams. Calls/meeting inside our network have choppy video/voice quality. People outside the network have no issues. Only if the traffic traverses the UTM does it have issue.

Does anyone have a writeup on how to configure the UTM so it doesn't mess with Teams traffic?

Thanks!

We had a lot of customers with VoIP and Webconf issues (Teams, Skype for Business and Zoom). The magic trick for us was to disable SYN flood protection. The difference was huge.

I have IPS exceptions (from and to) for the Teams ports (UDP 3478-3481)

Helped a lot

Did you do all the 'skip these checks' check boxes?

Also, when you say 'in and out. you means source ports in that range and another line with destination ports in that range?

correct, I skip all checks here.

And I have two services in this rule: 1:65636 -> 3478:3481 and vice versa

Essential is to skip flood protection check
