FYI:
The problem appears to be software issue that has started after January 1, 2006. During the system cleanup, any new/saved messages are erased.
(However any messages before December 31 are test ok)
The systems in question were both running 4.5 software. (Y2K software patch)
I also disabled the system cleanup function (as stated above). However it took several attempts for the system to recognize this change.
If you remove the cleanup function, there may be several intermittent problems.
I don’t think Executone/Intertel will support the VX2 VMS any more.
To the best of my knowledge you can’t upgrade VX2 to a VX3 (dungle conversion).
