Quality of service (QoS) settings

Note: If you're using non-Lumen internet access, please obtain required QoS settings from your service provider. Lumen cannot modify our managed device configurations (i.e. settings on IP phones). Work with your internet service provider to determine the correct QoS settings to configure your router properly.
