I rarely look at the CDR reports. Now, having the need I am reviewing and finding that up to four entries per call, both inbound and out bound are being placed on the report.
Currently running:
PBX Firmware: 10.13.66-17
PBX Service Pack: 1.0.0.0
As I have never modified anything under /etc/asterisk/cdr* I am puzzled. (I have removed the telephone numbers for obvious reasons.) This is my cellphone calling to test results.
