Do GPO set port ranges set for client impact Teams Room ports?

Question

We have a few Teams Room Systems that are randomly using ports outside of the configured ranges we have set within our Teams Admin Center for meetings. It's causing an overload to our voice queue when it occurs, and dumping the video traffic as a result. So my question is this- if there is an old Skype related GPO still hanging out in our AD environment, and a user who has this GPO schedules the meeting, will their GPO settings override the Admin portal settings and honor their port ranges instead of those we have configured? We've opened a MS ticket that was escalated up to the product group, and they haven't figured out why, or communicated with us much at all for that matter. So any help here would be appreciated. The documentation on the behavior is lacking in both Teams and Skype.

Hi @TheJKP

Teams tag is mainly focused on the general issue of Microsoft Teams troubleshooting. According to your description, your question is not in our support scope. I can only provide some related suggestions for your reference:

1.In Microsoft Teams, the meeting and calling settings configured in the Teams Admin Center should take precedence over any GPO (Group Policy Object) settings related to Skype for Business.

If there are state lingering gPO Settings related to Skype for business in your active directory environment, they should not impact the meeting settin GS In Microsoft Teams. Teams has been selected Policies and Configurations that are managed through the teams admin center.

2. I suggest you implement Quality of Service (QoS) in Microsoft Teams: Quality of Service (QoS) in Microsoft Teams allows real-time network traffic that's sensitive to network delays (for example, voice or video streams) to "cut in line " in front of traffic that's less sensitive (like downloading a new app, where an extra second to download isn't a large deal). QoS uses Windows Group Policy Objects and Port-based Access Control Lists to identify and mark all packets in real -time streams. This helps your network to give voice, video, and screen share streams a dedicated portion of network bandwidth.

For how to implement Quality of Service (QoS) in Microsoft Teams, you can refer to this document: Implement Quality of Service in Microsoft Teams - Microsoft Teams | Microsoft Learn
