Hi,
We use auto qos on our interfaces to configure voice priority (Catalyst 9300) :
interface GigabitEthernet1/0/X
switchport access vlan 10
switchport voice vlan 20
auto qos trust dscp
spanning-tree portfast
service-policy input AutoQos-4.0-Trust-Dscp-Input-Policy
service-policy output AutoQos-4.0-Output-Policy
We have a Cisco phone on this port (7841) but it seems that there are no packets matching for EF :
sh policy-map int gi 1/0/19
GigabitEthernet1/0/19
Service-policy input: AutoQos-4.0-Trust-Dscp-Input-Policy
Class-map: class-default (match-any)
