We have an MICS (Ctx 1.1) with two trunk groups: one for public calls that go to live operators, one for employee/family calls that go to the auto attendant (NAM 3.0). The office manager wants to know if calls to the "public" trunk group can go to the auto attendant after-hours, where callers will hear the after-hours greeting. Right now the AA is back-up for the live operator group, but only after 7-8 rings. Can we program it to shift to the AA immediately (i.e., only 1-2 rings) at 5:00 p.m.? Thanks.
