Priority (802.1p) has to be set properly before the phone is able to connect to anything residing in a specific VLAN ! Only the phone is residing in the specified VLAN, it has no effect to e.g. a PC connected with the second ethernet socket (PC).
The VLAN tagging is made by the kernel (as opposed to vlan_net_priority, which sets tagging made by the phone's incorporated switch)
