+# Implement Quality of Service (QoS) on Surface Hub
+
+Quality of Service (QoS) is a combination of network technologies that allows the administrators to optimize the experience of real time audio/video and application sharing communications.
+ 
+Configuring [QoS for Skype for Business](https://docs.microsoft.com/windows/client-management/mdm/networkqospolicy-csp) on the Surface Hub can be done using your [mobile device management (MDM) provider](manage-settings-with-mdm-for-surface-hub.md) or through a [provisioning package](provisioning-packages-for-surface-hub.md). 
+ 
+ 
+This procedure explains how to configure QoS for Surface Hub using Microsoft Intune. 
+
+1. In Intune, [create a custom policy](https://docs.microsoft.com/intune/custom-settings-configure).
+
+    ![Screenshot of custom policy creation dialog in Intune](images/qos-create.png)
+
+2. In **Custom OMA-URI Settings**, select **Add**. For each setting that you add, you will enter a name, description (optional), OMA-URI, data type, and value.
+
+    ![Screenshot of a blank OMA-URI setting dialog box](images/qos-setting.png)
+
+3. Add the following custom OMA-URI settings:
+
+    Name | OMA-URI | Data type | Value
+    --- | --- | --- | ---
+    Audio Source Port | ./Device/Vendor/MSFT/NetworkQoSPolicy/HubAudio/SourcePortMatchCondition  |  String | 50240-50279
+    Audio DSCP | ./Device/Vendor/MSFT/NetworkQoSPolicy/HubAudio/DSCPAction  |  Integer | 46
+    Video Source Port | ./Device/Vendor/MSFT/NetworkQoSPolicy/HubVideo/SourcePortMatchCondition   | String | 58300-58339
+    Video DSCP | ./Device/Vendor/MSFT/NetworkQoSPolicy/HubVideo/DSCPAction   |  Integer | 10
+    Audio Process Name | ./Device/Vendor/MSFT/NetworkQoSPolicy/HubAudio/AppPathNameMatchCondition  |  String | Microsoft.PPISkype.Windows.exe
+    Video Process Name | ./Device/Vendor/MSFT/NetworkQoSPolicy/HubVideo/AppPathNameMatchCondition  |  String | Microsoft.PPISkype.Windows.exe
+
+
+4. When the policy has been created, [deploy it to the Surface Hub.](manage-settings-with-mdm-for-surface-hub.md#manage-surface-hub-settings-with-mdm)
+
+
+>[!WARNING]
+>Currently, you cannot configure the setting **IPProtocolMatchCondition**. If this setting is configured, the policy will fail to apply.
