Are you connecting the phone to the wall socket, and then the PC to
the "link" socket on the phone?

If this is the case then it's working as it should do.. the HP switch
NAS is authenticating the PC's MAC, and opening the switchport on the
correct VLAN for the PC, and so the phone will be on that VLAN too -
they're on the same ethernet segment. If you've got a PC linked via
the phone, and you want the phone to be on one VLAN, and the PC on the
other I believe you have to configure the switch-port as a trunk, and
then configure the phone accordingly.
