Is ip phone picking up ip address?
Did you try to put other working phone on the same switch port with computer in cascading ?
Is data and voice vlan are configured on connected port ?

Apply this on the swith:

Switch(config)#interface gigaethernet 0/1
Switch(config-if)#switchport mode access

Switch(config-if)#switchport access vlan 50

Switch(config-if)#switchport voice vlan 10

Subtitute de VLAn number by yours and test...

yes the phone is getting an ip fine. just not the pc.

i need to create a vlan 10 on the switch ?

What if it is just a 3com switch that does not support vlans.

no, you don't need to have ip phone and pc on different VLANs

you just need to make sure your phone and pc are using same frame types if they are on same VLAN.... try giving your pc static address and see is there any communication between pc and gateway. if there is, then you need to check your DHCP, cause if you are using different DHCPs, it can cause your address requests looping... if you still don't have connection between pc and gateway, even after you tried setting address manually, see does switchport use dot1q or dot1p...
