We have a scenario that phones are up and running, no issue, provisioned and working extremely well. But randomly, phones have started freezing up - there is the typical screen displayed, but the phone doesn't react on pressed keys, stopps responding to ping and only a hard restart (unplug/plug power) can help. It's starting to happen on several phones.
