Does anyone know if the 3com 3C17025 (which supports NBX phones and IEEE 802.3af ) would work with Cisco 79xx phones for PoE ?

Many thanks.

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.
