with a night service its either on or off when on it picks up after the first ring, if you want more rings then what you nned to do is, set your AA to answer after 2 rings, and during the day go under feature 982 pswd operator(spell out using the dial pad) then turn answer lines to off, and at night turn answer lines to yes. This is the only way to get what you are wanting.
Hope it helps
