Brian<BR>Roy mentioned the Netgear FS108p (with external power adaptor,<BR>noiseless) as 8-port device. There is also a "larger brother" of it, the<BR>FS116P, which also comes with an external power supply, does PoE on<BR>eight of its 16 ports. I have no idea of your overall bandwidth<BR>requirements, but if it is only about phones, 100 MBit should be by far<BR>sufficient for those 20 devices, so you could cascade switches (like<BR>plugging two FS108p into non-PoE ports on a single FS116P, for<BR>instance). This is of course the cheapo way of doing it. Getting a<BR>proper multi-port switch, perhaps even a "real brand" one would be (ask<BR>the drooling sales droids out there) would be the real deal.<BR><BR><RANT><BR>Talking about NetGear switches, I once bought a 24port Gigabit Netgear<BR>switch, noiseless, external PSU.
