Thanks linus for the reply..

We have a mpls connection to our azure cloud..

we had requested our ISP to apply QOS on the WAN router or at specific device where it classifies and prioritize the teams traffic. But, they replied that QOS on MPLS is not recommended.

Also want to highlight that these issues occurs only when our BW utilization is exceeding our limit (100mbps) is it might be the reason? This same story when i put across the ISP engineer they told that if the BW limit exceeds then their WAN router will starts dropping or slowing the traffic flow since it seeing the BW surging past 100mbps.

Thirdly, please advise is there a QOS can be applied on Teams ? via powershell ? i was going through one document .

https://docs.microsoft.com/en-us/microsoftteams/qos-in-teams#choose-initial-port-ranges-for-each-media-type

Please advise..

Hi,
So you can see that the utilization exceeding your limit and then the issues starts, then it is probably related to that.

I don't know the reason why you send Teams traffic via the MPLS connection you have direct to Azure, it might be better for you to use your regular Internet Connection. The MPLS connection probably have some limitations (due to cost) and you probably have more bandwidth on your regular Internet connection.

Thanks Linus.
We have a dedicated express route configured for azure infra.
during normal days when there is not much Teams traffic, we do not have any user complains.
