My system is an Avaya with Partner VM R3. Currently, I have AutoAttendant set to answer my calls and then calls are redirected to the appropriate extensions. I have programmed a night service button, however, when it is on my calls just ring and my voicemail does not pick up. I want ext 16 voicemail to pick up at night with no rings (this phone is always set to DND and VMS cover). I know this can be done but I need help.
