One thought on “How to configure QoS for ShoreTel/Mitel phone on Cisco Switch”

  1. I believe auto qos only does COS values which Mitel doesn’t use, they use DSCP markings.
    These are our configuration for Mitel phone.
    interface GigabitEthernet1/0/3
    switchport mode access
    mls qos trust dscp
    spanning-tree portfast
    end
