Full Restore is not restoring voicemail

Preformed a full system backup on our production machine and moving it over to new hardware. I moved the backup file over and preformed a restore. Afterwards everything looked ok except, when i went to browse the extensions all of the voicemail sections were set to disabled when in the original machine they were enabled and setup.

I opened the backup file and found the voicemail.conf file which was complete. I then opened the new machine that i just restored and the conf file was using the default settings.

Did i do something wrong in the restoration process?
