Guys,
I have my 7912 phone connected to the CME and it gets IP I can make calls, etc. I now wish to connect the phone to the PC but I can't seem to get an IP. Can someone see what I'm doing wrong here.

Hi
Can you configure the switch port mode as access instead of trunk?

If I take out the trunk and have only

interface FastEthernet0/1/1
switchport access vlan 21
switchport voice vlan 22
spanning-tree portfast

The phone neither the computer gets an IP. The phone gets an IP if we have
!
interface FastEthernet0/1/1
switchport access vlan 22
spanning-tree portfast
!
This also allows the computer to get an IP but the computer IP is within the voice subnet IP and I don't want this. Do I have to do any configuration on the phone to ensure it allows the computer on its eithernet port as in assign the switch's PC port to the VLAN I wish the computer to be in?
Thanks for your assistance
OK. I moved the configuration to the actual switch which I will be connected to and it is working the way it should. You were correct, there was no need for the port to the phone to be a trunk.
Thanks for the assistance
