I very much doubt it. I bought a 4400 PWR to test with our Siemens 
Optipoint handsets, which also support 802.3af. The two do not work 
together. The official response I was given was that it is due to 
different detection algorithms in use by the various vendors. In the end 
we purchased some PowerDsine kit to supply the power, which is supposed 
to be the most compatible with a range of vendors 8023.af kit.
