These are instructions to create a basic catch-all policy for all traffic generated from a machine running 3CX PhoneSystem which tags all traffic with a DSCP value of 56.
Create a Local Policy for QoS
- Run “gpedit.msc”
- Go to the “Local Computer Policy -> Computer Configuration -> Windows Settings” node.
- Right-click on “Policy-based QoS” and click on “Create new policy …”
- Set the “Policy Name” to “All Traffic”
- Set the “DSCP Value” to 56
- Click the “Next >” button
- Select the “All Application” radio button
- Click the “Next >” button
- Select the “Any source IP address” radio button
- Select the “Any destination IP address” radio button
- Click the “Next >” button
- Set the “Select the protocol this QoS policy applies to” field to “TCP and UDP”
- Select the “From any source port” radio button
- Select the “To any destination port” radio button
- Click the “Finish” button
Apply the New Policy Immediately
- Run “gpupdate.exe”
Checking QoS is Applied to Outgoing Traffic
Running Wireshark will allow you to check that outgoing traffic is indeed being tagged with the correct DSCP value.
