hi Gonzalo,

thanks for your kind response.

I'm using verto and i was able to add

audioParams: {

googEchoCancellation: true,

googAutoGainControl: true,

googNoiseSuppression: true,

googHighpassFilter: true,

googTypingNoiseDetection: true,

googEchoCancellation2: false,

googAutoGainControl2: false,

googDscp: true,

within verto init.

well, my chrome still didn't want to mark the media packets :=)

i tried this on win7 and an older version of chrome (Version 49.0.2623.110 m) i had hands on.

Im going to try this with latest chrome on both win10 and linux.

maybe this is going to work :=)

as for dscp rewriting, i can do it easy, but when chrome does a video streaming ( e.g. youtube ) and makes a webrtc call, it should somehow give priority to webrtc call bofore video striming :=)

Also, unfortunately, many clients are not be able to re-mark media packets generated by webrtc call

we need to find a solution on the browser itself.

Hi Tihomir,

DSCP marking depends really on the browser and OS platform as its internal modules are the ones building up and tagging the Media information.

My understanding is that Chrome DSCP config settings is being there for couple of years (Set 'googdscp' to true) , just bear in mind that depending on the platform and OS you may need to test it.

https://bugs.chromium.org/p/webrtc/issues/detail?id=5836

I found this defect on Mozilla Browser website which still open:
https://bugzilla.mozilla.org/show_bug.cgi?id=1249575

Apart from setting DSCP value at the source which is the recommended options for QOS endpoints, remember you can always rewrite at any entry point in your network and make sure that DSCP value is honored and prioritize end to end.
