It is the Comdial "in skin" 8-port card voice mail--I haven't taken the front off of the ksu yet...but it should be just a card.
I don't recall seeing anything else...but the ksu is on the wall in a large "server" room with many PCs. Perhaps I overlooked the VM. Perhaps it isn't in the KSU as I ASSumed. I was thinking that it had the AA 4 port card and THAT was what was acting as the AA. Well, let me go back there next week and take another look. I have some manuals for the KeyVoice PC-based equipment and am somewhat familiar with them. Thanks.
