Show isdn history (NOT SHOWING CALL HISTORY)

[MarekGrover]

Hi all,


I am trying to see if my ISDN (backup) circuit has been active recently. I have tried this command:

>#show isdn history


output:
---------------------------------------------------------------------------------------------------------------
ISDN CALL HISTORY
---------------------------------------------------------------------------------------------------------------
Call History contains all active calls, and a maximum of 100 inactive calls.
Inactive call data will be retained for a maximum of 15 minutes.
---------------------------------------------------------------------------------------------------------------
Call Calling Called Remote Seconds Seconds Seconds Charges
Type Number Number Name Used Left Idle Units/Currency
---------------------------------------------------------------------------------------------------------------
---------------------------------------------------------------------------------------------------------------


Do I have to turn the logging on as I'm sure it has been active....


Many Thanks,

Jimmy
