Hi, I have a couple of questions about the settings in the Teams admin portal -> Meetings -> Meeting Settings -> Network.

 

It looks like you should be able to define ports for the different modalities (voice, video, screen share), as well as a tick box for enabling QoS markers.

1. I assume inserting QoS markers means that the client will tag its own traffic as such: audio - DSCP 46, video - DSCP 34, and sharing - DSCP 18.  Is that correct?

2. Does this work at this time?  I have been doing some testing, and tested like a month ago, and didn't see any changes when changing to port range for each modality to 55000s, and I don't see a tag set.  Checking with Wireshark.

3.  If this does work, I would presume it would apply for all media, whether or not it is in a meeting?  It's confusing because it's in the meeting section of the admin portal, but I would guess it should still apply in a peer to peer call, video call, screen share, PSTN call, etc, correct?

 

Thanks!

What I’ve heard latest is that these settings won’t mark the DCSP values to data at this point!
