ICX7150-48zp : LLDP MED Voice policy UNKNOWN for MiVoice Connect phones on 2.5G ports

I have a support ticket open with our vendor, but I'm hoping others have seen and resolved my issue.

I'm deploying Mitel 69XX series phones to several new stacks of icx7150 switches (a mix of 48zp and 48pf).  I'm using LLDP MED network policies to set the voice vlan and qos setting.  This is working as expected on all standard GigabitEthernet ports (ie. all ports on the PF switches and N/1/17 to N/1/48 on the ZP switches).  However, the phones are reporting "Unknown Policy, Untagged" for the Voice application when they are connected to any of the 2.5GigabitEthernet ports (N/1/1 to N/1/16 on the ZP switches).

I'm deploying two LLDP MED policies, both include the 2.5g ports that have phones connected:
lldp transmit-interval 15
lldp tagged-packets process
lldp med fast-start-repeat-count 10
lldp med network-policy application voice tagged vlan 213 priority 5 dscp 46 ports ethe 1/1/16 ethe 1/1/25 to 1/1/48 ethe 2/1/1 to 2/1/48 ethe 3/1/1 to 3/1/48 ethe 4/1/1 to 4/1/48
lldp med network-policy application voice-signaling tagged vlan 213 priority 3 dscp 24 ports ethe 1/1/16 ethe 1/1/25 to 1/1/48 ethe 2/1/1 to 2/1/48 ethe 3/1/1 to 3/1/48 ethe 4/1/1 to 4/1/48

Port ethe 2/1/12, which I'm using for testing, is a 2.5GigabitEthernet port.  Here's its port config:
interface ethernet 2/1/12
spanning-tree 802-1w admin-edge-port
inline power power-by-class 2
trust dscp
!

And here's its LLDP Neighbor details:

Currently we're working around the issue by moving phones off of these ports, but that's an ugly process in one of the switch closets.

Has anyone else experienced issues with LLDP and or Mitel phones connected to 2.5GigabitEthernet ports on ixc7150-48zp switches?

I have not personally seen anything like this. Your best bet would likely be to open a support case and have it looked at properly by our support team. Out of curiosity, what code are you running?
