I recently had a down VS-VML. After a reboot it came back to life and everything functioned correctly except for it will not light the message keys on the phones. I was able to manually light the the lamps from station to station and checked the VM to make sure the ports 3&4 were programmed to light message lights. I also checked the mailboxes and made sure the defeat message waiting box was not checked. Any feedback would be greatly appreciated.

Check in System Integration, Message Notification that the voice mail is dialing the correct MWL code.
