• Date range
• Account / Reseller

• End Reason

Export options include CSV, Excel, and PDF. For daily revenue reports, set “Group By” to Gateway or Area Code.

💰 Profit Analysis Using CDR Data (VOS3000 CDR Analysis)

VOS3000 automatically calculates profit as:

Profit = (Billing Rate × Duration) − (Clearing Rate × Duration)

You can view this directly in Business Analysis → Revenue Analysis → Profit Report. The system shows profit per gateway, per account, and per prefix.

Gateway	Total Minutes	Billing Revenue	Clearing Cost	Profit	Profit %
BD Mobile Route A	12,450	$224.10	$174.30	$49.80	22.2%
UK Landline	8,920	$80.28	$66.90	$13.38	16.7%

🔧 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.
