Setting DSCP QoS for Wildix devices

To set DSCP (Differentiated Services Code Point) QoS (Quality of Service) for all the Wildix devices (WP4X0 series phones, media gateways):

Note

Note: occasionally routers / firewalls / operators can block traffic with DSCP settings different from 0 (prioritized traffic could be dropped), in such case:

  • Administrator must disable globally DSCP QoS in WMS Settings -> PBX -> SIP-RTP
  • User can disable QoS separately for WebRTC Phone (Web Phone on Chrome) in Collaboration Settings -> Web Phone
  • User can disable DSCP settings in Android app -> Advanced Settings, in Phone app on Vision series phones and on WP600AXX series in Settings -> Developer

Setting QoS Policy for Windows

You can use QoS Policy as a central point of network bandwidth management across your entire Active Directory infrastructure by creating QoS profiles, whose settings are distributed with Group Policy.

QoS traffic management occurs below the application layer, which means that your existing applications do not need to be modified to benefit from the advantages that are provided by QoS policies.

Prerequisites for QoS Policy on Windows

It is possible to use QoS policy to manage bandwidth for computers or users with the following Microsoft OS supported by Wildix Collaboration:

...

  • Install Integration Service in Collaboration Settings -> Extensions 
  • Enable Direct RTP in Collaboration Settings -> Web Phone

Location of QoS Policy in Group Policy

In Windows Server 2016 Group Policy Management Editor, the path to QoS Policy for Computer Configuration is the following:
