All 3 reporting mechanisms are found in the Configuration Management under Diagnostics/Call Detail Records.
Real-Time Active Calls
Real-time active calls is a display of all currently active answered calls in the system. Details of the call indicate the Originator and Destination of the call as well as the start time and duration of the call from the time it was answered. The information displayed for the calls is automatically refreshed every 30 seconds. The rate of the refresh can be changed by selecting the current value and then editing it with a new value.
when from = user1, to = user1, status=F we know that user1 rejected the call
when from = user1, to = user2, status=E we know that user2 rejected the call (if there is no call established event (S) before, we know that user2 never answered the call and rejected it instead. If there is an (S) status event before, then user2 normally ended the call)
In the code (the cdr scripts) the call_direction field is never populated.
In the cdr scripts it is declared like this: "# call_direction char(1) Plugin feature see below ", but is never mentioned again.
In the sipXcom wiki only info on this field is : 11. call_direction Direction of the call
Two interesting discussions were found about call_direction are here:
