Hi not sure if anyone can assist as I am new to QoS and wondered if there were any proper guides when using the Cloud based SfB along with PSTN Calling. (e.g. No SfB Server on site) I found this...

Hey Peter,

(Author of those articles checking in)

I am curious as to what is causing the traffic not to be marked. Are you able to test on a machine that is not domain joined? (Should be able to export those Registry Keys and import them on the test machine)

*EDIT* - I think I found the issue.

Go to the GPO Editor and navigate to 'Computer Configuration>Windows Settings'

Right-click 'Policy-Based QoS' > choose 'Advanced QoS Settings ...'

Go to the 'DSCP Marking Override' tab

Check 'Control DSCP Marking requests from applications and services'

Select "Allowed'

I can't update the Perficient blog post since I am no longer employed there.

But I will try to figure out the PowerShell GPO cmd to create this entry

Hopefully this works for you!
