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.
