Hi, all!
Check the configuration on ONT and OLT, on ONT the Voice WAN interface should be with vlan and the 802.1P of vlan should be 5 ，then on OLT when you create service-port， the service port must bind the correct traffic table created in advance.
Eg：
traffic table ip index 10 cir off priority user-cos 0 priority-policy tag-In-package
service-port 1 vlan 3016 gpon 0/2/0 ont 1 gemport 1 multi-service user-vlan 3016 tag-transform translate inbound traffic-table index 10 outbound traffic-table index 10

port vlan eth 1 translation 3016 user-vlan 3016
port dscp eth 1 1 ----------------bind the dscp to pbit mapping table with index 1 to eth 1
