[VoiceOps] Old PA System setup

[Darin Steffl]

VP-1124D

Looks like a 1 amp, 24v will be enough according to their calculator. So
instead of shelling out $70 for one, I think a 24v poe with 1 amp output
should also work for us if we just grab the right pins on the ethernet
cable.

Anyone see why using a poe wouldn't work? We have lots of Ubiquiti 24v
laying around.
