Night service will only control if AA to answer (main greeting) or human, you!.
If people enter extension and it goes straight to vmail then the user invoked that option (Feature 987) which is what you should do when you leave your office.

There are 2 buttons right below Line 1 and Line 2. Those are both intercoms.

When paging a phone, you just insert a * (star) before the extension number.

SO, Intercom*11, will page extension 11

To program on a button, feature 00, press the button you want to program, then press the left intercom and *xx (where xx is the extension number)

As far as paging all the phones, you will need to have them in a calling group (1-4), hten you can page the group to page them all.

Asked under Partner. The Admin phones for they SYSTEM is 10 and 11. The VM can be administered from anyone with a password.

Comment back with whatever you mean about "extension list".

sounds like some of the phones are not in the paging group.
Changing the programming on a Partner system is done on either ext 10 or 11. At one of those ext's press the feature key and "00"
next press the left hand intercom twice
the display should say system programming
enter in "#502"
the display should say Calling Group Group:
press 1 the display will then ask for an extension.
enter in one of the extensions that isn't in the page group
the display will say 2 unassigned
press 1 to change to assigned
repeat the instructions for enter #502 for the next set/s
feature "00" to logout

You can not do phone system programming from anything EXCEPT Extensions 10 or 11.

This must be done from a phone with attendant features set. Typically ports 1 and 2. More than likely x10, x100, x1000 or something like this.

to change the time, again go to Ext. 10 or 11

step 2 enter 000
press next (or spkr phn button) for date
press next (or spkr phn button) for time
press fwd/dnd button
press fwd/dnd button again
press sel (or auto answer/mute button) to change am/pm
