We are running Cisco emergency responder 8.5 and have a Cisco WS-C3750-48PS-S Running c3750-ipbasek9-mz.122-55.SE6.bin. Emergency responder is seeing all but one phone plugged into Fa1/0/10. The phone is also not showing up in un-located phones either. That port is configured the same as all other ports. Does anyone have any idea why a particular phone wouldn't populate ER at all? I'm not sure what else to T-shoot. CDP is enabled globally and on that interface.

I am pending someone else move that phone to a different switch interface so I'll report back when I get some information on that.
