Configure QOS on HP 3500 switches

We are trying to configure QOS on HP 3500 switches but are experiencing "jitter" and "delay" when trying to make phone calls.

The network configuration is as follows;

HP 3500 (edge switch) connecting to a HP 5400 (core switch)

The voip traffic and data traffic is segmented via vlans

The qos configuration applied to the HP3500 and HP5400 switches / voice vlan is -

      qos dscp ef

 

qos dscp ef is configured on the voice vlan on both the HP 3500 (edge switch) and the HP 5400 (core switch)

 

qos has not been applied to the trunk interface between both the HP 3500 (edge switch) and the HP 5400 (core switch)

 

Can someone advise if the qos configuration is correct

OR do we require further qos configuration on the voice vlan

OR do we need to apply the qos configuration on the trunk interface between both the HP 3500 (edge switch) and the HP 5400 (core switch)

OR do we need to apply diffserv to the voice vlan

OR do we need to apply any further qos configuration on both the HP 3500 (edge switch) and the HP 5400 (core switch)
