QoS for SfB when using Cloud PBX and PSTN Calling
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!
If you have an ExpressRoute that has been configured correctly from your service provider then these packets will be honoured from Client to CloudPBX.
As Michael pointed out - your GPO will need to be configured to the right ports applied, you need to ensure that your internal lan and wan is configured as expected.
Got CloudPBX want QoS? Got to go ExpressRoute.
Not sure if this will help but found a site which says to check the skype logs for the ports etc. having found that it says qosenabled false and enableincallqos false
I have not seen anywhere that suggests I have to do something to enable this on the client, every site only mentions the GPO to enable QoS
you need to run the following powershell either from your on Prem Skype servers or in the Skype for Business Online shell. Without the media configuration being set to true the QoS ports will not be honured.
Set-CsMediaConfiguration –EnableQoS $true –EnableInCallQoS $True
Good luck and let us know how you get on?
Thanks but hitting an issue trying to do that, went through all the connection to the powershell module for skype but it says set-csmediaconfiguration is not recognized
Also on this technet site it states it won't work, although cannot be sure obviously.
