Have a customer with 6 CO lines and answering machine. CO 1-3 will go to Answering Machine when Night mode is activated. CO 4-6 will not. I just took this over and did not program it initially.

So what you are probably going to look at is the ringing.I would guess that lines 1-3 are ringing XXX group and lines 4-6 are ringing YYY group. Look at 406 and check where the trunks ring

that was it Thanks
