Step 2: Locate the CDR Record 📋

Search Method	Navigation	Best For
📅 Recent CDR Query	Data Query → Recent CDR	Calls from today or yesterday
📊 Historical CDR	Data Query → CDR	Older calls with date range filter
📞 Phone/Number Filter	Any CDR query + caller/callee filter	Finding all calls from/to specific number
💰 Amount Filter	CDR query + billing amount range	Finding overcharged or undercharged calls

Step 3: Execute CDR Modification ✏️

1. 📌 Navigate to: Account Management → Modify Cdr
2. 🔍 Enter search criteria to locate the specific CDR record
3. 📊 The system displays matching CDR records in the result grid
4. ✏️ Select the target record and click Modify

🔧 System Error	Software bug caused incorrect billing calculation	Both duration and amount corrected retroactively
💰 Billing Adjustment	Goodwill credit for service quality issue	Amount reduced or zeroed as customer retention gesture
📝 Data Entry Fix	Manual CDR import had wrong values	Corrected to match actual switch records

🔐 Permission Management for CDR Modification

🛡️ The VOS3000 modify CDR feature is protected by granular permission controls. Not all administrators have access to this sensitive function:

Permission Level	Modify CDR Access	Typical Role
👤 Super Admin	✅ Full modify access	System owner, technical director
👤 Admin	⚠️ Configurable (usually granted)	Senior operations staff
👤 Operator	❌ No access	Day-to-day provisioning staff
👤 Read-Only	❌ No access	Billing auditors, reporting staff

⚠️ Audit Trail and Compliance Considerations

📝 When using the VOS3000 modify CDR feature, operators should be aware of audit and compliance implications:

• 📊 VOS3000 maintains a log of all CDR modifications including: admin username, timestamp, original value, new value, and reason for change
• 🔍 The original CDR data is preserved in backup tables for forensic analysis
• 📋 Modified CDRs are flagged in reports to distinguish them from original records
• 🛡️ Excessive CDR modifications may trigger internal audit alerts
• 📞 Telco regulators may require justification for billing record alterations

Audit Element	What VOS3000 Records
👤 Who	Administrator username that performed the modification
📅 When	Exact timestamp of the modification
📊 What Changed	Field name, old value, and new value
📋 Which Record	CDR unique identifier (call ID, timestamp, session info)

🛠️ Troubleshooting VOS3000 Modify CDR Issues

❌ Problem 1: Modify Button Grayed Out

🔍 Symptom: The Modify button is not clickable or grayed out in the interface.

💡 Causes and Solutions:

• 🔐 Verify your admin account has Modify CDR permission — check with super admin
• 📅 CDR may be too old — some systems restrict modification to recent records only
• 📊 The CDR may have been already modified once and the system prevents multiple edits
• 🔧 Check if the CDR belongs to a locked or reconciled billing period

❌ Problem 2: Balance Not Updated After Modification

🔍 Symptom: Account balance does not reflect the CDR change after modification.

💡 Causes and Solutions:

• ⏱️ Balance recalculation may take a few moments — wait and refresh
• 🔄 The account may be in a locked or suspended state preventing balance updates
• 📊 Check if the account uses prepaid mode — balance updates may differ from postpaid
• 🔧 Restart the VOS3000 client to force a balance refresh if needed

❌ Problem 3: Cannot Find Specific CDR Record

🔍 Symptom: The target CDR record does not appear in query results.

💡 Causes and Solutions:

• 📅 Check the date range — the call may be outside the queried period
• 📞 Verify the caller/callee number format matches the stored format
• 📊 The CDR may have been archived — check archive settings
• 🔍 Use broader search criteria (wildcard) to locate the record

💡 Best Practices for VOS3000 Modify CDR Feature

Best Practice	Implementation
📋 Document Every Change	Maintain an external log of modification reasons for compliance
🔐 Limit Access	Grant modify permission to only 1-2 trusted senior admins
📊 Batch Corrections	For rate errors affecting many calls, use batch operations rather than individual edits
⏱️ Timely Corrections	Modify CDRs as soon as errors are discovered — don’t wait until month-end
🔄 Reconcile Regularly	Daily reconciliation catches errors early before they compound

❓ Frequently Asked Questions

❓ Which CDR fields can be modified in VOS3000?

📊 The VOS3000 modify CDR feature allows editing of the call duration and billing amount fields. These are the two fields that directly affect customer billing. Immutable fields include caller number, callee number, call start time, end time, and billing mode code. This design ensures that the factual record of the call (who called whom, when) remains intact while allowing correction of billing calculations. The restriction maintains data integrity while providing the flexibility needed for billing adjustments. 📋

❓ Can modified CDRs be reverted to original values?

🔄 Yes, the VOS3000 modify CDR feature allows administrators to view the original values and make further corrections if needed. However, there is no single-click “revert” button. To restore original values, an administrator must manually edit the CDR again, entering the original duration or amount. The audit trail maintains a complete history of all changes, so the original values are always recoverable from system logs even if not directly visible in the main interface. 📈

❓ Does modifying a CDR affect already-generated reports?

📊 CDR modifications in VOS3000 affect reports that are generated after the modification. Reports that were already generated and exported will not automatically update. For this reason, operators should regenerate any affected reports after making CDR corrections. The report management system can regenerate historical reports with corrected data. It’s recommended to establish a policy of regenerating reports whenever CDR modifications are made. 📋

❓ Is there a time limit for how long after a call a CDR can be modified?

⏱️ By default, VOS3000 does not impose a hard time limit on CDR modification. However, many operators implement soft policies restricting modifications to the current billing period (typically 30 days). Once a billing period is closed and invoices are issued, CDR modifications should be avoided unless absolutely necessary. Some deployments configure system parameters to lock CDRs after a specific number of days as a compliance measure. 📅

❓ How does CDR modification interact with the system log?

📝 Every CDR modification in VOS3000 is recorded in the system audit log. The log entry includes the administrator username, timestamp, original values, new values, and the CDR identifier. This audit trail is accessible through the system log audit interface. The log entries are retained according to the system’s log retention policy and cannot be deleted by administrators — providing a tamper-proof record for regulatory compliance and internal auditing. 🔒

❓ Can resellers or agents modify CDRs for their accounts?

👥 No, the VOS3000 modify CDR feature is restricted to system administrators with explicit permission. Resellers and agents cannot modify CDR records, even for calls under their own accounts. This restriction exists because CDR modifications affect billing accuracy and financial records. Only trusted system-level administrators should have this capability. If a reseller reports a billing error, the system administrator must investigate and perform the modification on their behalf. 🛡️

📊 Modify CDR and Billing Reconciliation Impact

💰 When CDR modifications are made in VOS3000, the impact extends beyond the individual call record to affect the entire billing reconciliation chain. According to the VOS3000 V2.1.9.07 Manual, the modify CDR feature triggers automatic balance recalculation for the affected account. This means that when you reduce a CDR billing amount from $5.00 to $3.50, the account’s balance is adjusted upward by $1.50 to reflect the corrected charge.

However, this adjustment only affects the account balance — not any previously generated reports or exported billing data. Operators who have already generated monthly billing reports before making CDR modifications must regenerate those reports to ensure the financial figures match the corrected CDR data. This is a common operational mistake that leads to discrepancies between what the customer’s account shows and what the billing report indicates. 📋

🔧 Billing reconciliation steps after CDR modification:

1. 📝 Document the reason for each CDR modification with customer reference
2. 🔄 Verify that account balance reflects the corrected amount
3. 📊 Regenerate any affected billing reports for the period
4. 📋 Update clearing reports if carrier-side costs were also affected
5. 📧 Notify the customer of the billing correction if appropriate
6. 📊 Cross-reference the modification with the system log audit trail
7. 💰 Reconcile the opening and closing balances to confirm accuracy

⚠️ Regulatory and Legal Considerations for CDR Modification

⚖️ VoIP operators operating in regulated telecommunications markets must be aware that CDR modifications have legal and regulatory implications. In many jurisdictions, telecommunications regulators require that all billing records be accurate and auditable. The ability to modify CDRs — while necessary for correcting legitimate errors — also creates the potential for billing manipulation if not properly controlled. VOS3000 addresses this concern through strict permission controls (only authorized administrators can modify CDRs) and comprehensive audit logging (every modification is recorded with who, when, and what changed).

However, operators should also implement organizational policies such as requiring dual approval for CDR modifications above a certain threshold, periodic audits of CDR modification patterns, and separation of duties between the person who identifies the error and the person who authorizes the correction. These policies, combined with VOS3000’s technical controls, create a robust framework for billing integrity. 🛡️
