As a user, open your User panel on your iceBar toolbar and among the user functions section, you will see the Contact History button.
Click on this button to open up your contact history window.
If you do not see this button, right click on your iceBar toolbar anywhere in the grey/white area, and click on the Contact History option from the drop down list.
As a Team Lead, Supervisor or Administrator, open the journal tab on iceManager and use the filters to search for a specific user. You will see a list of the user's completed contacts and contact details for each.
