c2960 S switch port voice configuration

Level 1

I have a NEC IP PBX SV8100 connected to the access port of the C2960S switch and have configured the port as follows; the voice VLAN is VLAN 500

interface GigabitEthernet1/0/1
 description "NEC UNIVERGE SV8100"
 switchport access vlan 500
 switchport mode access
 spanning-tree portfast
end

should I add the following commands onto the switch port for proper handling of voice traffic, or what commands are appropriate for the list below if any or none, leave the configurations as above. I understand the configiures below are recommended for cisco IP Phones

Switch#configure t

Switch(config)#mls qos

Switch(config)#interface GigabitEthernet1/0/1

Switch(config-if)#switchport priority extend trust

Switch(config-if)#mls qos trust cos

Switch(config-if)#switchport voice vlan dot1p

Switch(config-if)#switchport mode access

Switch(config-if)#switchport access vlan 500

Switch(config-if)#switchport voice vlan 500

I'm thinking I would just do:

interface GigabitEthernet1/0/1
  auto qos trust
