Make sure you have prioritize all apps use by the phones. You can run a report for src=IP of a phone and review all the apps/traffic generated by the phone. If there's any unknown traffic from the phone, you may want to classify the unknown and add it to the QoS policy. Thanks.

Also dont forget to prioritize in both directions.
If I recall correctly the QoS is always setup on the outbound (egress) interface.
