I have a network with a cisco 4500 switch with phone and data vlan.  If I hook my pc up directly to the switch I get a link light and an ip address.  If I hook my cisco ip phone up to the wall jack, I get an ip address.  When I hook my pc up to the phone when the phone is hooked up to the wall jack, my pc gets an ip address.  But if I hook my pc directly to the wall jack, my pc does not even show it is connected.  I have tested this on 3 different computers and I get the same result with this 1 wall jack.

Anyone have an suggestions?

I would first check the port configuration on the switchport that is connected to that jack to see if anything is different there when compared to other (working) ports.

That sounds really strange but despite the phone working I would assume some cabling issue.

Make sure the in the port configuration you have:

switchport mode access
switchport vlan <vlanID>
switchport voice <vlanID>

do not forget, I mention that if I plugged my pc directly to that switchport it works so I know the data vlans are working along with the voice

Do you happen to have a cable tester? Try that.

I would say check your vlan tagging configuration. It doesn't make sense but it seems like if the voice data is not present then it doesn't recognize a direct - data connection.

I'm sure you did that but just to make sure ;) You did check from the wall jack to the patch panel?
Also just to make sure I would check the port config on the switch to rule that out.

Is the switchport gigabit, or 100Mb? Also, maybe there's a crossover patch cord somewhere.
