Does anyone know where I can get the Voicemail Utility Program (VUP) for an Atlas Telephone system? Its the System 56 Voicemail being used on an Atlas XE 60. This dates back to the later 1990's.
Any help would be appreciated.

I did't think the EX 60 is quite that old.

What software version is your voicemail? The VUP software is version specific. It also can be programmed from the system telephone.
