Tim,
When doing voice vlan, portfast is automatically configured wether in trunk mode or not.
here are 2 examples
no trunking specified
int f0/1
switchport trunk encapsulation dot1q
switchport voice vlan 105
switchport access vlan 106
spanning-tree portfast
trunking specified
int f0/2
switchport trunk encapsulation dot1q
switchport voice vlan 105
switchport mode trunk
switchport trunk native vlan 106
spanning-tree portfast
on the 2nd example, since you are trunking, you should use "switchport trunk native vlan" in place of "switchport access vlan". The spanning-tree portfast is automatically configured when you configure the voice vlan (I believe)
I hope that is what you were looking for :-)
