Scott,
If you use the the below config then does it mean the the connection b/w the
phone and the 3550 doesn't create a 802.1 trunk. How is it possible then for
the connection to support a vlan tag for voice traffic in
order to differentiate b/w voice and data traffic.

mls qos
!
interface fastethernet 0/10
switchport mode access
switchport access vlan 10
switchport voice vlan 100
mls qos trust cos
Rgds,
Yasser
