unable to ping from vlan to vlan (pc only)

going to be something simple, im sure!
just connected a laptop into my vlan20 (voice) network and its not picking up an ip from my dhcp servers.  tried statics, still nothing.
i can route from my shoretel phones across to the data vlan1 and PCs from vlan1 to vlan20 fine.  Just computers on the vlan20 arent working.
Ideas?
