IP Phone Bypass on an 802.1x port?

I have an Avaya IP Phone plugged into a port on a HP Procurve 2530 POE. The port is configured for 802.1x authentication which is successfully authenticating a PC (connected via the ip phone). The port will auto-assign into either VLAN 2 or VLAN 4 depending on the PC connected (via Microsoft NPS policies) and a port that fails authentication is placed into the "restrict" VLAN. All ports are tagged in the Voice VLAN. 

I've read that by providing an IP Phone its voice VLAN via LLDP-MED (with the "voice" command under the VLAN config) the IP Phone can bypass the 802.1x authentication process. Firstly, is this actually true? I've tried to set this up and can't get it to work the phone will not boot. Relevant config is below, can anyone help? Thanks

radius-server host 172.28.9.37 key "password"

aaa authentication port-access eap-radius

aaa port-access authenticator 1-20
aaa port-access authenticator 1 unauth-vid 45
aaa port-access authenticator 1 client-limit 3

...(same on each port upto 20)

aaa port-access authenticator active

...

vlan 2
  name "adm"

  name "restrict"

Resolved. I tried some cases, and finally, only need enable EAPoL forwarding on IPPhone (I used NEC IPPhone).
