I have recently taken over an office that had previously set up their comdial system. I am working in the office with no one that was around when the original system was installed and I can't find the original manual. All I'm trying to do is change the outgoing greeting that one gets when they reach the voicemail (not sub-mailboxes). Can anyone please advise on what I can do to re-record this greeting? We know very little about the system and had to download a new programming manual but it has been little help. It's a DX-80 system. Any help will be much appreciated as I am really stumped on this one! Thanks!!
