Can you read the Event Log which will show the events that happenedThis problem is not related to the orignal voice lost issue
It looks like there is a problem with the bus. Perhaps it may be shorted which causes communications to be lost
Remove the devices like rio, ucm keypads etc one by one and see if the communications recovers
Connect a UCM and log in using Comfigurator so do not remove the UCMLog in with UCM and look at the UCM IO at the bottom of the screen The messages will show when communications is lost or receivered
