Nothing specific (yet). I've been charged with supporting the system for the near future and I just figured the most recent manual(s) would be best. I've got to figure out how to turn on and set up the ACD features, CID (but I think we need hardware for this) and beef up the VM system. We are currently on Eclipse 2.00 and I've no idea how to update that to get the benefits of a newer version.
Check your list of options on the menu screen. If a type of ACD isn't there then you will need a download or a different CPU card. CID needs a PRI, T1 or a CID in line adapter. The voicemail is regulated by the green dongle unless it's a card.
