Not sure anyone else seen this before that after a new installation (fresh install after factory default), couple phones were configured with basic settings (line ext. users, etc.). All phones were in function that could call each other. However the next day, all phones lost configs, and only 525G phone was instead configured with default extension 100. So I guessed the config was not saved properly, and certainly something happened overnight in the lab (power, or something else, not sure). Anyway, my point is once the new configs was applied, UC320 automatically saved the config locally, and should not lose the config even during the reboot process. So what could be possible to cause the UC320 to lose the saved config? Corrupted config, I guess?
