Cisco 7800 Enable HookSwitch

         For some reason there is no information on how to turn on the HookSwitch on for a Cisco 7800 without Cisco unified communication manager.  After a long support call, and much digging, it turns out that you CAN enable the hookswitch without Cisco unified communication manager.  Go to the phones webpage (Firefox worked best), Login as Admin, click on advanced (top right), goto the Voice tab, Click on the User tab, Scroll to the Audio Volume section, Change the drop down for electronic HookSwitch Control to Yes.  That's it!
