if you are config that port as Truck port then yes u need to define
native vlan but it is not nesscary to biuld port as truck port whne u you
only connect Cisco Ip fone .if you use switch port access vlan xxxxx and
switch port voice vlan xxxx its should work .spanning tree port fast is
not define by default you have to specafied on the port .

Many thanks ,

Sameer
