Did you shut down the voicemail card properly before taking the system offline? Assuming its a VMS-X or VMP that you have installed in the IPK -- there is a switch on the side of the card that faces you when looking at the chassis -- the switch will be labeled "MB" or "MAKE BUSY". Turn the switch into this position, wait 45 seconds and pull the card out of the slot. Press the card back into the slot, and return the switch to its original position.
It can take up to 5-6 minutes for the VM system to fully boot up.
