I've got a CIX670 with a voicemail box that nobody has the password for. All I have is eManager over the LAN and a funky serial cable I handmade a year ago to clean out VM space on what I think was called an IPV8. I don't remember if I used putty or if I had to have some sort of executable to manage the voicemail system. Before I drive out to this old dinosaur to connect to the PBX can someone give me the steps (and/or apps) needed once I get there?

Or can this be done over eManager?

Thank you.
