I am implementing Office Communication Server and want to try the IP Phones, so I started looking into POE switches. I don't have the correct terminalogy. I am looking at HP ProCurve Switch 3500yl 48 port features, I want to make sure it has the feature I am looking for. What I want is, with connection to a single port in switch, I want to have the laptop and the phone connected. So I believe it is going to give two different IP adresses with one cable. Does this feature have a name? With this I can have twice as many people connected to the swtich.
