Programatically retrieve local hostname for hoteling in Open UI

Hello,

During non-prod testing, we realized that CTI hoteling does not work in Open UI with our current configuration.  Per document 1578061.1 (and other posts), we understand that the new way to use the hoteling setup involves activating the 'Setup Hoteling' button and 'Work Edit' text controls on the CTI toolbar, which then allows a user to manually enter a hostname in the text box and click the related button.  We've validated that this works.  However, our customer does not want their CSRs to have to manually enter any value in order to log into CTI.

Our strategy for a workaround involves trying to capture the local hostname in the toolbar related javascript while it is being built, and then predefault that value into the 'Work Edit' control.  We've manged to pre-populate values in that control, but we are unable to access the local hostname from the server application.  Is there a way to retrieve this value through code or some other mechanism?
