This morning found that 8 (of total of 45) handsets (type 5212) had flashing green display (no text in that display) and no functionality.

After disconnecting/reconnecting each handset they rebooted and now function OK.

Log details as follows...

Any idea what might be happening? Could the 3300 ICP be failing? Set the system to reboot tonight in the hope that a clean start might help...

Thanks
