Teams VOIP signalling protocol and TCP port numbers?

I understand MS teams is using HTTP/HTTPS TCP port 80/443 for call setup,

 

So If I want to apply QoS how can I capture the specific HTTP/HTTPs traffics for MS-Teams? excluding all the other web browsing traffics. The requirement is only to prioritise MS-Teams voip signalling traffics.

 

Thanks

    You don't need to set up QOS on the setup traffic, just the UDP.

      Hi Ed,

      Thanks for the reply,

      I am pretty new to Teams telephony system, wondering if you can shed a little more light?

      When I worked on traditional VOIP systems, like Cisco phones, we normally put voice signalling traffics (SIP/H.323/Skinny) into CS3 with dscp marking 24.

      Wondering why it is unnecessary to apply the same for MS Teams?

      Thanks
