DPhil,
You are unable to "trace" an agent, only the station. However, if you are using systems such as eCAS(call accounting system)or CentreVu you can get most any information on an agent that you need.
As to the COR question, when an agent logs into a phone that phone's COR no longer matters. All of the information for that phone, who and where it can call, are all based on the COR of the Agent. Example, I created an agent id for myself and a COR so I could service observe ANYONE(I'm the administrator, why not); however I neglected to set my COR on my agent to the admin COR. It gave me a brief shock when I tried to service observe while logged in. I realized then that the phone's COR makes no difference what so ever.
Hope this is helpful.
