Teams VOIP signalling protocol and TCP port?
I understand MS teams is using HTTP/HTTPS TCP port 80/443 for call setup, and RTP/UDP for data plane,
My question is how can I apply QoS for MS Teams signalling traffics? (in another word, How can I capture/classify the HTTP/HTTPs traffics only for MS Teams call setup, excluding other normal web browsing traffics)??
Plane | Media Traffic Type | User source port | Destination port | Protocol |
Data | Voice | UDP 50000-50019 | UDP 3478-3481 | RTP over UDP |
Data | Video | UDP 50020-50039 | UDP 3478-3481 | RTP over UDP |
Data | Screen Sharing | UDP 50040-50059 | UDP 3478-3481 | RTP over UDP |
Signalling | TCP 80 and 443 | HTTP/HTTPS |

Best of luck on your implementation. Thanks for reaching out.

Hi, I see you mention high UDP ports for Teams traffic. Despite extensive searches, I cannot find a Microsoft document that references high UDP or TCP ports for the correct functioning of Teams. Can you point me to the Microsoft source for these high UDP ports please?
I am referencing: https://docs.microsoft.com/en-us/microsoft-365/enterprise/urls-and-ip-address-ranges?view=o365-worldwide#skype-for-business-online-and-microsoft-teams
Probably referring to the recommended initial port ranges for policy based QoS

To add to ChrisHoardMVP response of QoS, adding QoS to the signalling portion of the call wouldn't change the call quality or performance of the call as that's just part of the initial setup. I'd concentrate on just QoS on the media portions.
If you do still want to put QoS into place on the signalling portion, you can explicitly define the source/targets as well, listed on the Office365 URLs and IPs page https://docs.microsoft.com/en-us/microsoft-365/enterprise/urls-and-ip-address-ranges?view=o365-worldwide#skype-for-business-online-and-microsoft-teams
