I suspected the Polycom IP500 of being power on spare. Inside the phone it even has a Pulse H2005A PoE transformer but since it's all surface mount I can't see what its connecting too. The newer IP330, IP430, IP550 all seem to be "normal" power on Data. Very interesting. I suspected the Polycom IP500 of being power on spare.
