And about the 802.1x ?
The phones can work as passthrough and force the PC to use 802.1x ?
What configuration do we put in the switches? Do we put the switch as
"access" (with 802.1x) or "trunk" (without 802.1x) ?
Thanks

It actually depends on the switch model. Some put the port into

Hopefully one day Cisco will finally make their own products and become
uniform instead of buying several companies and glue'ing them all
together to get an ethernet switch that works. At least they got the
routers right :)

If configuring with Cisco switches, I'm pretty sure they pull
the
information for which VLAN to operate in from the switch. You
have to
configure the switchports on the Cisco switch like so:
interface fastethernet 0/1
switchport trunk native vlan <your data vlan>
switchport mode trunk
switchport voice vlan <your voice vlan>
spanning-tree portfast trunk
etc.
