I needed a conference phone for work. We used to use the old Polycom conference phone when we were analog, but we went VOIP some years ago.
I've managed to buy a second-hand (thanks Ebay) Nortel 2033, for a good price. This one:

Before it arrived, my IT guy was fairly confident we'd get it working. I will see him later today.
I've located an operations manual on line.
Now, it comes with the Nortel Power over Ethernet (PoE) Interface Module (NTEX11GAE6). This one:

I don't know yet whether our Ethernet is configured to will supply power.
Therefore I may have to be able to supply DC power to the PoE module. The power supply was not part of the deal.
If I could work out the voltage and VA required, I can organise power.
So that is the question - how do I find out voltage (important) and power consumption (less important).
I've checked out the circuit board in the PoE module but it gives me no clues.
Online I can see power supplies listed, but cannot find specs or read the labels in the images. These ones:

So if anyone can tell me the specs for the supplied DC power, I'd be grateful.
While I'm asking, does anyone know the wiring for the extension microphones. These are the ones commercially available:

Too pricy for me. I reckon I can pull the mikes from the old analogue unit and use them, if I can work out the wiring to the plugs that go into the Nortel phone. They are your usual four-wire RJ10 connectors.
