I recently upgraded a MICS with a 8 port NAM from T1 to 7.1 software. All programing was documented before change out. The situation is an outside line appears and rings on four sets with one of those forwarding to voicemail after four rings. This set has a mailbox but the forward goes to the main auto attendant greeting. The line in question is set to no answer in NAM. Any ideas on how to make the call go direct to the sets mailbox?
