Some POE devices are not class 4 (high power) which the conference phone might require.
Just a thought. My Grandstream GAC Conference Phones need more power than some switches output.

The switch is an HP2920 and supplies up to class 3, PoE+, 802.3af and 802.3at, the CP860 is class 0 so more than enough power. Also, as I mentioned, we have other CP860’s that are plugged into the same switch and are working fine.
