Before I start......this is not in production. It's in my basement.

Tinkering with a Rolm Redwood 3.2 system. Going to take a stab at getting voicemail working on it, but I only have the admin manual from the original release, which has 0 info on setting up voicemail. I think I've got most of it figured out, ATI ports assigned to a voice processing department and all, but not sure on turning message waiting lights on and off. Is there a code the VM box can dial to turn these off and on?

I know from a ROLMphone you HAVE to do it using the call me button on a 400 set, but is this possible from analog ports designated for voicemail?

I know this is an old, old system....hopefully someone remembers. Or maybe someone has the documentation from a 3rd party VM system like Repartee or Keyovice that has integration notes on the Redwood??
