So I think I have this beast nearly gelded. It still has some fight in it. I have the schedule set in the Keyvoice yet it will not switch between modes for day and night. It shows "day" 24 hours a day except for lunch, that works. So my day/night schedule does not work. I have verified the date and time are correct on the Keyvoice.

I cannot find where to set line ringing for extensions. I need to add immediate ring on all lines for an extension but I can't see where it is done. This DXP is a lot like the DSU but this part is not the same. I have a 13A so I can use hypertermial as it turns out.
