I am having difficulty in setup and test of exec override feature. Have tried to program using pc with vodavi pc database version 4.24 and uploaded to stations I have setup, but when trying to use feature will not allow the override. I have exec override checked, and blocking is not checked off. I know must be missing something, any help would be appreciated. Also is there any tie in with the off-hook voice over? And can it be done to analog ports as well as digital to include override on external page zones?
