I have a client who has a 4 line setup on a dx 120. The first 3 are set up to ring and then call forward no answer to the auto attendant. The fourth line is used as a day care line and they are wanting to ring directly to that extension and if no answer go directly to that extension voicemail. I've tried and the only thing I can get it to do is the same as the first three and cannot seem to get it the way they are wanting it. Any help with this issue would be much appreciated
