It looks like another computer is using the SIP softphone on your computer. That doesn't work but it probably won't warn them either. It is a mistake made when users move around and don't confirm the station name before logging into Interaction Connect.
In IC Business Manager open a Session Managers View. You need the Supervisors/system license to see this view.
Use the drop down at the end of the Interaction Connect line to show the list of sessions open between CIC and the Interaction Connect. The station shows the computer name for the SIP Softphone connections. You can also see the user Name.
Find that user in the directory and right click and log off that user, if you have the security setting to allow forced logoff.
If not, get the user at the station to log off or change station.
I hope that helps.
Cheers,
