Day/Night switch for Asterisk

I have a Trixbox CE with Cisco 7940 phones. Calls go to Night and Day IVR based on Time conditions in the system. I need a hotkey on the Cisco phone to manually switch between the day and night mode and also show the system status (is it in day/night mode?) Currently I can dial *280 to override the time conditions and put the system in night mode during the day, but I need a hotkey and also s visual indication to show night vs. day like a flash, button illumination, etc. Deliverable is making this happen and also provide detailed instructions so I can implement the same thing on my other systems. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
