Setting up an VLAN for VOIP Phones

Hello all,
Cisco Catalyst Express 520
Cisco Catalyst 2960 SI
Polycom VOIP Phones (different Models)

Ok. Here's the situation. I need to separate out the Phone connections from the computer ones for QOS purposes. I want to be able to plug computers and phones into whichever data ports are most convenient. Is there a way to have the above switches automatically detect when a phone is the device plugged into it and asign that port to a VLAN, or do I need to statically assign them (or just physically change all the wiring.....)

So assuming the polycom phone uses vlans and has a similar method of detecting the correct vlan to come up on as say an avaya ip phone, mitel or shoretel, then this example will help you.

I am looking into doing this. Sorry for the late response. I will get back to yo when I have a chance to do this

OK... I finally have a chance to do this. However, the artcial was on a 37xx series switch with layer three. I don't think the 2960 and 520 have layer three.

No but the switchport configuration will be pretty close to what is in that document and it will support the seperate voice and data vlan with a phone connected and a PC into the phone.  So given the switchport configuration if the phone plugs in it uses 802.1q trunking and knows to send its traffic down the correct vlan, if the PC plugs in the data will flow on vlan 10 as the PC is NOT doing the 802.1q trunking.  So given this configuration just from a layer 2 perspective, the phone or PC can plug into any given port and they will be on the correct vlan.  The caveat is how do your phones operate?  You might have to set up some specific dhcp entries to feed the phones their correct vlan, etc..
