Enable QoS

[JulienM]

Hello,
I am trying to enable QoS on the 3CX server.
I changed the "MSRTPTOS" parameter with the value 46 and restarted my server (Debian).
When I make a call, I see that my phone (Yealink) correctly tags the DSCP field to the value "EF" :



However, for flows from the server to the telephone, the DSCP field is not tagged (CS0) :



Do you have an idea ?
Thanks in advance

Use nftables. Refer to my post over here to see what I do to easily accomplish QoS on outgoing traffic from the server:
