D-Link DIV-140 Network Router User Manual


 
D-Link DIV-140 User Guide 39
The third section of the page displays the total duration of calls for selected port and direction in first section of page. Also you can use button
‘Reset Call History’ to permanently clear the call history log from device memory. Please note that after resetting the call history log it can not be
restored back.
The call history is maintained in SDRAM and due to system limitations it is transferred to persistent storage only periodically (say every 1 hour). The
information displayed in call history page may not be accurate if the power goes off before the call history is saved to flash. Also due to limitation
of memory only most recent 100 calls are stored in memory.
