Common CDR Discrepancies & Real Fixes (Manual References)
Here are the most frequent billing issues and exact solutions:
1. CDR Not Showing / Missing Calls
Cause: SS_MAX_CDR_PENDING_LIST_LENGTH is too low (default 5000). Fix: Increase to 15000–25000 in System Parameters (Manual Page 178).
2. Wrong Duration or Revenue
Cause: Incorrect timezone or billing cycle. Fix: Set correct server timezone and check “Billing Cycle” in Rate Group (Manual Page 245).
3. One Call Shown Twice (Duplicate CDR)
Cause: Re-invite or re-transmission. Fix: Enable “Ignore Duplicate CDR” in System Parameters.
4. Profit Shows Negative
Cause: Clearing rate higher than billing rate. Fix: Set “Lowest Profit Rate Limit” in Routing Gateway or block the route.
