RE: T28P - Firmware 2.73 - no PC port
UPDATE:

I've solved and fixed the issue. Ended up being a problem with Cisco SG300 switches. Disabled CDP, and the auto voice vlan/smart port settings.

Now phones work properly with LLDP / DHCP option 132. Come up on voice VLAN. Best of all, PC port is working fine.
