In certain situation intercom can get to some unpredictable state and it's behavior indicates failure. Anyway it can be caused by some memory leak, state of some watchdog etc., in this case sometimes HW factory via RESET button helps and intercom will be functional again. Also this is generaly the last step before you will raise RMA request and everytime you will do it, 2N technician will ask you to perform this!
