You're close. You need to change the "private" line to "unassigned" for the recectionist phone. This will take care of it ringing to her during the day. For the night problem you need to go into "ringing service" under "services" and build a ringing group that has no exts. assigned. Then go into "night" under services and change "extra dial" to "none" and under "line settings" for the private line change the group to the one you just built. Also go into (F983) "AA", "lines", and change Ans. or AA to "N". This will make it only ring the phones you want 24/7. The problem with the call going into the correct mailbox Can be resolved by setting the "DRT delay" in "feature settings" under "system programming" to a lower # of rings than your assistants call forward no answer timer. The call will come in and ring your assistants, if no answer drt to your phone, if no answer go into your voicemail. You may want to lower your call forward no answer timer so the caller isnt ringing forever before going into your mailbox. The easiest solution would be to have your line ring your phone instead.
Hope this helps.
I can type this step for step if you provide the ext. #'s and the line in question.
