Since the Cisco 79XX phones preceded the PoE standard, they are
different--polarity is reversed.

IANAE, but as I understand the PoE devices, there are two types--one
always applies -48VDC to the brown pair while the other senses (as per
the PoE spec.) whether the device at the other end requires power.

I'm not willing to risk a $300 Cisco set, so I'm still using the wall
wart.  Is anyone providing LAN power to 79XX phones at a reasonable cost?
