asterisk users - Mar 2007 - Polycom Power

I have a 501 with traditional power and a 301 with PoE. I rightfully assumed
that the traditional power from the 501 would work on the 301.

How do I get the PoE to work? Do I use the Polycom PoE cable in addition to
whatever PoE injection method I use? I have a Cisco PoE injector that works
on my Cisco AP350 and my 7960. No combination of this injector, the Polycom
cable, and the phone result in success.

I have 18v PoE injectors that I use for other things, but I hear that
802.3af is 48v, therefore probably wouldn't work.

How do I use Polycom PoE?

You'll probably have to get different injectors, or a new PoE switch.
The newer Cisco PoE switches do speak 802.3af, but many of the older
Cisco PoE products do not.  The original Cisco PoE implementation was
proprietary and does not conform to 802.3af.
