Proper settings to minimize chance of jitter with Ringcentral

Not sure if I have setup QoS for VOIP correctly to interact with RingCentral on my switch.

I know almost nothing about this aspect.  Switch is Aruba 2540.

RingCentral is seeing jitter when they diagnosed it, I want to make sure that the switch is prioritizing the voip traffic at the best priority over data but I have no idea if this is the right way to do it, or if there is a best-practice type of approach?  The phones are on vlan 10, phone plugs into switch, pc plugs into phone, PoE is used.  In this instance I just want to confirm the switch is properly configured to prioritize traffic, if the problem is upstream, it's upstream, I am just concerned about the switch at this point.

I don't know what the dscp mapping table looks like so maybe ultimately I'm missing the priority?
