So this may be a bit complicated, but try to stay with me...
First off, your STAR looks to be programmed on 1 for day settings. Usually people program their day settings towards the bottom (18,19 or 20) to leave room for conditional routing (holidays, etc.) towards the top. STARs look for matches from top to bottom, if it doesn't find a match for the conditions programmed, it'll use the default application programmed in the root of the STAR application. That's where your Night setting is programmed. This is all well and good, but it seems you guys want to kick it into night mode manually (9860). Your CO Trunk Group will have Day Ring in Destination and Night Ring in Destination. When your system is in Day mode (not to be confused with your STARs programming), it'll follow that. When your system is manually put into Night Mode (9860), it'll follow the Night Ring in Destination. Seems you guys want to automatically go into an "after hours" state using STARs so you won't likely be using the Night Mode (9860). Instead, follow your default application in the root of the STAR and see where it's going. What you want to happen can be accomplished by sending the default application to a Call Routing Announcement with Day and Night Greetings removed, Digit Translation table programmed for Timeout to Transfer to Extension - Hunt Group with members being an Extension List with all the phones you want to ring. Recall will then be programmed to ANOTHER Call Routing Announcement with Day and Night Greetings removed and Timeout set to Transfer to mailbox -- receptionist's mailbox or whatever general mailbox you guys have set up.
