phone stating in LLDP that it is half duplex
I have issues with T4X series phones showing in their LLDP they send to the Ethernet switch that they are half duplex. Both the phones WAN port and the Ethernet switch are set for Auto Negotiate. I see the same in the LLDP if both the phone and the Ethernet switch are set to 100 M full duplex. The phone I tested with is a T41P Firmware Version 36.71.19.6 and Hardware Version 36.0.0.0.0.0.0. I am troubleshooting a delay audio issue and want to clear up this apparent mismatch so as to eliminate it being the cause.

Here is the output of the switches debug of LLDP.
