Ok sounds like you need to add 212 to Night Service then.
Voice Mail system:
Auto Attendant under Lines is where you tell the lines to answer and how many rings and which table to answer.....this is a 24/7 setting.
Phone system:
Service Modes is where you can tell a phone, phones or AA to answer right away on demand or automatically.
If you were to add 212 to the night service then any phones told to ring in normal mode will now give a half ring then ring 212 only.
I gather 212 would then end up in a mailbox after so many rings.
Or to have AA answer calls the enter the DN of voice mail instead of 212.
Feature 985 will tell you what vmails DN is.
It does seem odd to ring just one phone at night, no option for people to get a hold of a specific person or at least their voice mail.
