Answer

To optimize QoS settings for prioritizing VoIP traffic, you need to configure your network devices to recognize and prioritize voice packets, ensuring low latency and minimal jitter. This involves setting up QoS policies on routers and switches to classify and manage traffic effectively, often using DSCP markings and priority queues.

<!-- BEGIN COPY / PASTE -->
    class-map match-any VOIP
      match ip dscp ef
    policy-map PRIORITIZE-VOIP
      class VOIP
        priority percent 30
    interface GigabitEthernet0/1
      service-policy output PRIORITIZE-VOIP
    <!-- END COPY / PASTE -->

Additional Comment:

Identify VoIP traffic using DSCP EF (Expedited Forwarding) marking, which is typically used for voice.
Apply a policy map to allocate a percentage of bandwidth specifically for VoIP traffic.
Ensure that the QoS configuration is applied to all relevant interfaces handling VoIP traffic.
Regularly monitor and adjust QoS settings based on network performance and usage patterns.
