I had a system that did that as well. We just replaced it. I noticed that sometimes during a reboot the software would just not start up for some unknown reason.

There was a Daylight savings time patch that will update some key files. Toshiba tech support will have to let you know where to get that file. This is not an upgrade through VM Manager, but an offline update. Sometimes this will fix some problems, but it did not work for me when I had this same issue.

The system also has the original configuration for the database as a backup on the flash drive. If the system is getting stuck trying to load the voicemail database then this could be a solution. You would have to know how to boot up to DOS, or use a CF card reader to copy the files.
