Voice VLAN DHCP option for Shoretel (Mitel) Phone

[chomunsu]

Hi, I have HP Procurve 6200 & 3500 switch. I am have a issue to detect the shoretel phone to automatically detect the voice vlan. 

I setup following

data vlan 10 - all port untagged

voice vlan 80 - all port tagged

dhcp-server pool "VOIP"
authoritative
default-router "10.10.80.1"
dns-server "68.238.112.12,71.252.0.12"
network 10.10.80.0 255.255.255.0
range 10.10.80.10 10.10.80.254
exit

vlan 80
name "VOIP"
tagged 2-24
ip address 10.10.80.1 255.255.255.0
qos dscp 101110
voice
dhcp-server
exit

The phone got vlan 10 dhcp address not the voice vlan address. 

What could be wrong?

Here are the lldp status:

One point it showed following;

TEST(config)# show lldp infor rem 17

Here are more from the switch. it is bit weird that it comes up as working but not consistant result

TEST(config)# show mac-address 17

As it shown, the port detects but not assign IP address when even assgined vlan 80. I check the phone IP address and it was showing vlan 10 address not vlan 80 address.
