After noticing an error with the Avaya manager after trying to change User Rights a reboot was scheduled on the phone system. After timed reboot was performed all configuration was lost. All extention labels, all short codes, all call routes missing. In the Manager directory on the C drive there are dated .bak files labeled. They appear to be created after changes were made on the system and merged. Can we use one of these .bak files to restore the configuration? From the Restore Binaries and Configuration option nothing changes after changing the .bak to a cfg and importing the file. Is there another process for this?
