TrueConf for Windows users can improve the quality of their video calls and conferences using traffic prioritization or QoS. With this setting, you can prioritize data, such as audio, video and media streams, in your application. If you set up QoS for your TrueConf client application data, the network router will identify it in passing traffic and give it the highest priority, which will significantly improve your communication quality. This article describes how to set up QoS step by step.

Step 1: Preparing to Set QoS Permissions

  1. Press Win+R and enter regedit in a window that opens. The registry editor will open.
  2. Open the following folder: HKEY_LOCAL_MACHINE → SYSTEM → CurrentControlSet → Services → Tcpip → Parameters.
  3. Set DisableUserTOSSetting to 0.


If this parameter does not exist, you should create it.
  1. Open the following registry folder: HKEY_LOCAL_MACHINE → SYSTEM → CurrentControlSet → Services → Tcpip → Parameters → QoS
  2. Create a string parameter Do not use NLA and set it to 1.


Step 2: Setting QoS Permissions

  1. Click Win+R and enter gpedit.msc in a window that opens. The local group policy editor will open.
  2. Right-click Policy-based QoS.


  1. In a window that opens, select Advanced QoS Settings. Make the following settings:
  • Check the box Control DSCP marking requests from applications and services
  • Select Allowed


Click ОК to save these settings.

Step 3: Creating Policy-Based QoS

  1. Right-click Policy-based QoS and select New in the context menu.
  2. Set up QoS rule parameters by specifying:
  • Name in Policy name
  • Traffic class value equal to 46 in Specify DSCP Value


  • TrueConf folder path in Only application with this executable name


  • Protocol ТСР and UDP



Click Finish to save these settings.


If you need to set up a QoS rule for computers that are on the same domain as yours, follow the instructions on how to distribute TrueConf client application configuration using group policies.
