There are two ways to configure voice and data vlan on a switch port:

interface FastEthernet0/3
 switchport trunk encapsulation dot1q
 switchport mode trunk
 switchport voice vlan 31
 no ip address
 spanning-tree portfast trunk
-----------------------------------------------------------------------

Recommended:

interface fastethernet 0/3
switchport access vlan 10
switchport voice vlan 20
switchport native vlan 10
spanning-tree portfast

Couple of questions:

Why 2nd choice is recommended?
Why native vlan has to be changed from VLAN 1 to VLAN 10

Thanks,

Richard
