Have you tried powering this particular phone on another inline power switch ? Just wondering if its a bad phone?

Hi Douglas,
It sounds like this bug (Thanks Met!);
CSCsi70300 Bug Details
NME Etherswitch Service Module Not Detecting Pre-Standard Devices
Symptom:
Pre-Standard POE devices are not powering up, link is down/down.
Conditions:
PreStd POE device must be connected to Etherswitch Service Module (ex. NME-16ES-1G-P) running 12.2(35)SE2.
Workaround:
Downgrade IOS to 12.2(25)SEE3
Further Problem Description:
Althought the NME runs 3750 IOS, the problem is not seen on a 3750 switch.
The IEEE 802.3af devices function fine (ex. 7961, 7941), only Pre-Std are affected.
Hope this helps!

If you need to run a later version of IOS for other features this defect is resolved in 12.2(40)SE or later.

I'm seeing similiar behavior on my Cisco 1801.
POE - power supply is connected and POE LED is green, but when I connect 7941 phone it does not power up.
I'm running IOS Version 12.4(11)T4.
The inline power config is set for auto on all ports and a 'show power inline' sees an 80 watt power supply, but nothing allocated to any of the ports.
Any thoughts would be greatly appreciated.
Thanks...matt
