Phones for Asterisk and single-pair old phone wiring?

I was thinking it would be easy enough to adapt a wall wart to power the
unit at the desks - here's a 24V 750mA unit for $13.50 each:

The DDW-220 pulls 300mA at 20VDC. Either attach a socket (Radio Shack) to
the power lead or hard-wire the wall wart.
Or perhaps you could run power over another pair of the old copper, if
available, to power multiple units from a larger DC power supply in the
datacenter.
Ah, the joys of legacy hardware...

That's what I said. Only more colorful. ;-)

I saw it, and even saved note of it. It's rather more of an industrial
design that is suitable (DIN rail mount, needs DC wired-in power supply),
but might be adaptable for our purposes. I having a feeling it's not
appropriate for this project, but it may come in useful for others. :)
