I'm currently working on a solution where we can input a phonenumber and a date period, to show all out-/ingoing calls AND "calls in absence" (not taken calls).
As i worked on it, i saw that zero duration calls aren't listed in the table "tbl_billing_data". after a quick google search, i found out that there is another table called "tbl_billing_error" which includes the calls with zero duration - but sadly without timestamps.
Where are the timestamps stored? If i use the CDR report function on the webinterface, i can see timestamps for zero duration calls, so i guess there must been saved somewhere...?
