VOS3000 CDR Query Date Range Maximum Interval Limit Best Configuration

VOS3000 CDR Query Date Range Maximum Interval Limit Configuration

๐Ÿ“Š A single CDR query spanning 90 days on a high-traffic VOS3000 system can return tens of millions of records โ€” enough to overwhelm the database, exhaust client memory, and freeze the VOS3000 interface for minutes. The VOS3000 CDR query date range limit, controlled by SERVER_QUERY_CDR_MAX_DAY_INTERVAL, prevents this by capping the maximum number of days a user can query in a single CDR search. The default of 31 days is designed to balance operational needs against database performance โ€” but understanding how to work within and around this limit is essential for every VOS3000 operator. โฑ๏ธ

๐Ÿ”ง Whether you are a reseller who needs to pull quarterly reports or an administrator protecting your database from runaway queries, mastering the VOS3000 CDR query date range configuration is critical. This guide covers the parameter details from the official VOS3000 2.1.9.07 manual, practical workarounds for large-range queries, and how this limit works alongside other CDR access controls. ๐Ÿ“‹

๐Ÿ” What Is VOS3000 CDR Query Date Range Limit?

๐Ÿ“ The VOS3000 CDR query date range limit specifies the maximum number of days a user can include in a single CDR query. When a user attempts to search CDRs with a start and end date that spans more than the configured maximum, the query is rejected with an error message indicating the date range exceeds the allowed limit. ๐Ÿšซ

๐Ÿ’ก Why this limit exists:

  • ๐Ÿ“Š Database performance: Large date range queries scan millions of rows, consuming CPU, memory, and I/O resources on the database server
  • ๐Ÿ–ฅ๏ธ Client stability: Returning millions of CDR records to the VOS3000 Client can cause memory exhaustion and application crashes
  • โฑ๏ธ Query timeout prevention: Long-running queries may time out before completion, wasting resources without returning results
  • ๐Ÿ›ก๏ธ Fair resource sharing: Prevents a single user from monopolizing database resources with an excessively broad query
  • ๐Ÿ“ž Operational continuity: Ensures the VOS3000 system remains responsive for real-time call processing even during heavy CDR analysis

โš™๏ธ SERVER_QUERY_CDR_MAX_DAY_INTERVAL โ€” The Core Parameter

๐Ÿ“ SERVER_QUERY_CDR_MAX_DAY_INTERVAL defines the maximum number of days allowed in a CDR query’s date range. Any query with a date range exceeding this value is automatically rejected. ๐Ÿ“‹

AttributeValue
๐Ÿ“Œ Parameter NameSERVER_QUERY_CDR_MAX_DAY_INTERVAL
๐Ÿ”ข Default Value31
๐Ÿ“ UnitDays
๐Ÿ“ DescriptionMaximum Interval for CDR Inquiry (Day)
๐Ÿ“ LocationOperation management โ†’ Softswitch management โ†’ Additional settings โ†’ Server parameter

๐Ÿ”ง How the 31-day default works: When a user queries CDRs with a date range of, say, January 1 to February 15 (45 days), VOS3000 calculates the interval: 45 days. Since this exceeds the default SERVER_QUERY_CDR_MAX_DAY_INTERVAL of 31, the query is rejected and the user receives an error. The user must then narrow the search to a maximum of 31 days โ€” for example, January 1 to January 31.

๐Ÿ“‹ VOS3000 CDR Query Date Range Limit Examples

๐Ÿ“Š Here are practical examples showing how the limit affects different query scenarios: ๐Ÿ’ก

๐Ÿ”„ Workarounds for CDR Queries Exceeding the Date Range Limit

๐Ÿ“Š When you need CDR data spanning more than 31 days, there are several approaches to work around the VOS3000 CDR query date range limit without increasing the parameter value and risking database performance: ๐Ÿ’ก

๐Ÿ“‹ Method 1: Incremental Queries (Chunk the Date Range)

๐Ÿ”ข Break your large date range into multiple queries, each within the 31-day limit. For example, to get 90 days of CDR data: ๐Ÿ’ก

๐Ÿ“‹ Incremental CDR Query Strategy (90-day range, 31-day limit):

Query 1: Jan 1 โ€“ Jan 31    (31 days) โœ…
Query 2: Feb 1 โ€“ Feb 28    (28 days) โœ…  
Query 3: Mar 1 โ€“ Mar 31    (31 days) โœ…

Total: 3 queries covering 90 days
Merge results externally (Excel, Python, etc.)

๐Ÿ“Š Advantage: No parameter changes needed; each query is database-friendly. Disadvantage: Requires manual effort to merge multiple result sets. For automated merging, use Python or a spreadsheet tool to combine the CSV exports.

๐Ÿ“ Method 2: CDR Text File Export

๐Ÿ“„ Use the VOS3000 CDR text file system instead of the database query. When SS_CDR_RECORD_TO_FILE is enabled, all CDRs are written to pipe-delimited text files in the cdr directory. These files can be searched, filtered, and analyzed using any text processing tool without any date range restriction. ๐Ÿ“‹

AspectDatabase QueryText File Export
๐Ÿ“… Date range limit31 days (configurable)No limit โ€” read any files on disk
๐Ÿ” Search capabilityRich filtering (account, gateway, etc.)Text processing (grep, awk, Python)
๐Ÿ“Š SpeedFast for targeted queriesSlower for large file scans
๐Ÿ”ง Setup requiredNone โ€” built into VOS3000 ClientEnable SS_CDR_RECORD_TO_FILE + rotation

๐Ÿ’ก For detailed CDR text file setup instructions, see our CDR text file export guide and CDR file rotation guide. ๐Ÿ”—

๐Ÿ“ก Method 3: Real-Time CDR Forwarding to External Analytics

๐ŸŒ If you frequently need large-range CDR analysis, consider forwarding CDRs to an external analytics platform (Elasticsearch, Splunk, custom database) using SERVER_CDR_REAL_TIME_REPORT_SERVER. External platforms typically have no date range restrictions and offer more powerful search and visualization capabilities. For setup instructions, see our real-time CDR forwarding guide. ๐Ÿš€

โš™๏ธ Method 4: Increase the Parameter Value (With Caution)

โš ๏ธ You can increase SERVER_QUERY_CDR_MAX_DAY_INTERVAL beyond 31 days if your database has sufficient resources. However, be aware of the implications: ๐Ÿ’ก

SettingRisk LevelImpact at 100 CPSRecommendation
31 days (default)๐ŸŸข Low~267M records maxโœ… Safe for most deployments
60 days๐ŸŸก Medium~518M records maxโš ๏ธ Only with powerful database server
90 days๐ŸŸ  High~778M records max๐Ÿšจ Risk of query timeouts and client crashes
365 days๐Ÿ”ด Very High~3.15B records maxโŒ Not recommended โ€” use external analytics instead

๐Ÿ–ฅ๏ธ Step-by-Step VOS3000 CDR Query Date Range Configuration

๐Ÿ”ง Follow these steps to configure the CDR query date range limit: ๐Ÿ“‹

Step 1: Configure the Parameter ๐Ÿ“Œ

  1. ๐Ÿ” Log in to VOS3000 Client
  2. ๐Ÿ“Œ Navigate: Operation management โ†’ Softswitch management โ†’ Additional settings โ†’ Server parameter
  3. ๐Ÿ” Locate SERVER_QUERY_CDR_MAX_DAY_INTERVAL
  4. โœ๏ธ Set the desired maximum day interval (default: 31)
  5. ๐Ÿ’พ Save and apply the configuration

Step 2: Verify the Limit โœ…

๐Ÿ“Š After configuration, test the limit by attempting a CDR query that exceeds the configured maximum:

  1. ๐Ÿ“… Open the CDR query window in VOS3000 Client
  2. ๐Ÿ” Set a date range that exceeds the configured limit
  3. โœ… Verify that the query is rejected with a date range error message
  4. ๐Ÿ“‹ Try a query within the limit and confirm it executes successfully

๐Ÿ”— The VOS3000 CDR query date range limit works alongside several other query size parameters that together control database load: ๐Ÿ’ก

ParameterDefaultPurpose
SERVER_QUERY_CDR_MAX_DAY_INTERVAL31Maximum days in CDR query date range
SERVER_QUERY_MAX_ONE_PAGE_SIZE200000Maximum records per page in results
SERVER_QUERY_MAX_SIZE30000000Total data query limit (items)
SERVER_QUERY_ONE_PAGE_SIZE10000Default records per page
SERVER_QUERY_NON_PAGABLE_MAX_LINES100000Non-pagable table max lines per page (1000โ€“200000)

๐Ÿ’ก Practical example: At 100 CPS, a 31-day query could return approximately 267 million records โ€” well above the SERVER_QUERY_MAX_SIZE of 30 million items. This means that even with a 31-day date range, the actual query results may be truncated by the total query size limit. The combination of date range and result size limits provides defense in depth against database overload. ๐Ÿ›ก๏ธ

๐Ÿ›ก๏ธ Common VOS3000 CDR Query Date Range Problems and Solutions

โŒ Problem 1: Reseller Needs Quarterly CDR Report

๐Ÿ” Symptom: A reseller needs to generate a quarterly CDR report (90 days) but the query is rejected.

โœ… Solutions:

  • ๐Ÿ“‹ Use incremental queries: three 31-day queries covering the quarter
  • ๐Ÿ“„ Export CDR text files and process them externally with Python or Excel
  • ๐Ÿ“ก Set up real-time CDR forwarding to an external analytics platform
  • โš™๏ธ Temporarily increase the limit for the specific query (then reduce it back)

โŒ Problem 2: CDR Query Returns Incomplete Results

๐Ÿ” Symptom: A 31-day CDR query returns fewer records than expected.

๐Ÿ’ก Cause: The total result count exceeds SERVER_QUERY_MAX_SIZE (30 million items), causing truncation. Or the query falls within the CDR query blackout window for some hours.

โœ… Solutions:

  • ๐Ÿ“Š Add more specific filters (account, gateway, call type) to reduce result count
  • ๐Ÿ“… Use a narrower date range and merge results
  • ๐Ÿ”ง Check SERVER_QUERY_MAX_SIZE setting if you need larger result sets

โŒ Problem 3: Changing the Limit Does Not Take Effect

๐Ÿ” Symptom: After changing SERVER_QUERY_CDR_MAX_DAY_INTERVAL, queries still fail at the old limit.

โœ… Solutions:

  • ๐Ÿ”„ Re-login to the VOS3000 Client after saving the parameter
  • ๐Ÿ”ง Clear the client cache and restart the application
  • ๐Ÿ“Š Verify the parameter value was saved correctly by re-opening the settings panel

โ“ Frequently Asked Questions

โ“ What is the default value for SERVER_QUERY_CDR_MAX_DAY_INTERVAL?

๐Ÿ“‹ The default value is 31 days. This means that by default, any CDR query in VOS3000 with a date range exceeding 31 days is automatically rejected. The 31-day default covers a typical monthly reporting cycle and provides a reasonable balance between operational needs and database protection. If your business requires larger query ranges, you can increase this value โ€” but consider the performance implications carefully, especially on high-traffic systems. ๐Ÿ”ง

โ“ Can I increase the VOS3000 CDR query date range to 365 days?

โš ๏ธ While SERVER_QUERY_CDR_MAX_DAY_INTERVAL can technically be set to 365 or higher, doing so on a production system with significant call volume is strongly discouraged. At 100 CPS, a 365-day query could attempt to return over 3 billion records โ€” far exceeding the SERVER_QUERY_MAX_SIZE of 30 million items and likely causing query timeouts or client crashes. For annual CDR analysis, use incremental queries, text file exports, or external analytics platforms instead. For CDR text file setup, see our CDR text file export guide. ๐Ÿ“Š

โ“ Does the date range limit apply to the CDR text file export?

๐Ÿ“„ No. The VOS3000 CDR query date range limit only applies to queries made through the VOS3000 Client and web interface (database queries). The CDR text file system writes all records to files on disk without any date range filtering. You can read, search, and analyze these text files using external tools (Python, awk, grep) with no date range restriction whatsoever. This makes the text file system the preferred method for large-range historical CDR analysis. ๐Ÿ”—

โ“ How do I export more than 31 days of CDR data for a reseller?

๐Ÿ“Š You have several options: (1) Use incremental queries โ€” run multiple 31-day queries and merge the results externally, (2) Access the CDR text files on the server directly โ€” they contain all records with no date range limit, (3) Use the real-time CDR forwarding feature to send records to an external analytics platform where larger queries are supported, or (4) Temporarily increase SERVER_QUERY_CDR_MAX_DAY_INTERVAL for the specific query (remember to reduce it back afterward). For the most robust long-term solution, option 3 provides unlimited analytical capability. ๐Ÿ’ก

โ“ Does the VOS3000 CDR query date range limit affect automated reports?

๐Ÿ“‹ The date range limit primarily affects manual CDR queries through the VOS3000 Client interface. Automated reports (configured under Report management) generate based on their own scheduling parameters. However, if an automated report’s date range configuration exceeds the SERVER_QUERY_CDR_MAX_DAY_INTERVAL, it may also be subject to the same restriction. Always verify that your automated report schedules are compatible with the configured date range limit. For more on reporting, see our CDR analysis guide. ๐Ÿ“Š

โ“ What other parameters control CDR query performance?

๐Ÿ”ง Several parameters work together to protect database performance: SERVER_QUERY_CDR_MAX_DAY_INTERVAL (date range limit), SERVER_QUERY_MAX_ONE_PAGE_SIZE (max records per page = 200000), SERVER_QUERY_MAX_SIZE (total query limit = 30M items), SERVER_QUERY_ONE_PAGE_SIZE (default page size = 10000), and SERVER_QUERY_CDR_DENY_TIME (blackout hours). Together, these parameters provide layered protection against heavy queries. For the blackout configuration, see our CDR query blackout guide. ๐Ÿ›ก๏ธ

VOS3000 CDR Query Blackout Secure Deny Time Configuration

VOS3000 CDR Query Blackout Secure Deny Time Configuration

๐Ÿ”’ Imagine this scenario: your billing team is running the end-of-month reconciliation, processing millions of CDR records to generate invoices, when a reseller launches a massive CDR query that consumes database resources and slows the entire billing run to a crawl. The VOS3000 CDR query blackout feature, controlled by SERVER_QUERY_CDR_DENY_TIME, prevents exactly this situation by blocking CDR queries during specified hours โ€” protecting your database during critical billing windows, maintenance periods, and peak processing times. โฑ๏ธ

๐Ÿ“Š The VOS3000 CDR query blackout is a server-level parameter that defines specific hours of the day when CDR queries are denied to all users through the VOS3000 Client and web interface. During these blackout hours, any attempt to query CDR records returns a restriction notice instead of results. This ensures that database resources remain fully available for billing calculations, report generation, and system maintenance without interference from ad-hoc queries. ๐Ÿ›ก๏ธ

๐Ÿ’ฌ Need to configure CDR access policies for your VOS3000 deployment? Contact our experts at WhatsApp: +8801911119966 for professional assistance with billing security and system optimization. ๐Ÿ’ก

๐Ÿ” What Is VOS3000 CDR Query Blackout?

๐Ÿ“‹ The VOS3000 CDR query blackout is a time-based access control mechanism that restricts CDR queries during designated hours. When enabled, users cannot search, view, or export CDR records through the VOS3000 Client or web portal during the configured blackout window. This protects database performance during periods when the system needs maximum resources for internal processing. ๐Ÿšซ

๐Ÿ’ก Why carriers need CDR query blackout:

  • ๐Ÿ’ฐ Billing run protection: Monthly reconciliation processes millions of CDRs โ€” concurrent user queries can cause severe performance degradation
  • ๐Ÿ“Š Report generation: Automated reports require exclusive database access to complete within acceptable timeframes
  • ๐Ÿ”ง Maintenance windows: Database optimization, index rebuilding, and data archival should not compete with query traffic
  • ๐Ÿ›ก๏ธ Data integrity: Prevents partial or inconsistent CDR views during data migration or settlement processing
  • ๐Ÿ“‹ Regulatory compliance: Some jurisdictions require controlled access to CDR data during audit periods

โš™๏ธ SERVER_QUERY_CDR_DENY_TIME โ€” The Core Parameter

๐Ÿ”’ SERVER_QUERY_CDR_DENY_TIME defines the hours during which CDR queries are blocked. The parameter uses a 24-hour clock format, specifying which hours of the day are denied for CDR access. ๐Ÿ“‹

AttributeValue
๐Ÿ“Œ Parameter NameSERVER_QUERY_CDR_DENY_TIME
๐Ÿ”ข Default ValueNone (no blackout by default)
๐Ÿ“ FormatComma-separated hour values (24-hour format)
๐Ÿ“ DescriptionNo CDR Query Time (24 hour) e.g. 18,19,20,21,22,23
๐Ÿ“ LocationOperation management โ†’ Softswitch management โ†’ Additional settings โ†’ Server parameter

๐Ÿ”ง Configuration format: The parameter accepts comma-separated integer values representing the hours of the day (0โ€“23) when CDR queries are blocked. For example, to block CDR queries from 6 PM to midnight, set the value to: 18,19,20,21,22,23. Each value represents one complete hour โ€” setting “18” blocks queries from 18:00:00 to 18:59:59.

๐Ÿ“‹ VOS3000 CDR Query Blackout Configuration Examples

๐Ÿ“Š Here are practical examples showing how to configure the VOS3000 CDR query blackout for different operational scenarios: ๐Ÿ’ก

โœ… No restriction(leave empty)None๐Ÿ“Š Default โ€” CDR queries available 24/7

โš ๏ธ Important note: The blackout hours are specified in the server’s local timezone. If your VOS3000 server is configured in UTC and your billing team works in a different timezone, you must convert the desired blackout window to match the server timezone. For example, if your billing team in Dhaka (UTC+6) wants to block queries from 6 PM to 10 PM local time, and the server is in UTC, the parameter should be set to 12,13,14,15,16 (6 PM UTC+6 = 12 UTC, 10 PM UTC+6 = 16 UTC). ๐ŸŒ

๐Ÿ“‹ Step-by-Step VOS3000 CDR Query Blackout Configuration

๐Ÿ–ฅ๏ธ Follow these steps to configure the CDR query blackout on your VOS3000 system: ๐Ÿ”ง

Step 1: Determine Blackout Window โฑ๏ธ

๐Ÿ“Š Identify the hours when CDR queries should be blocked based on your operational needs:

  • ๐Ÿ“… Billing run schedule: When does your monthly/daily reconciliation run?
  • ๐Ÿ”ง Maintenance windows: When are database optimizations scheduled?
  • ๐Ÿ“Š Report generation: When do automated reports run?
  • ๐ŸŒ Timezone alignment: Convert desired blackout hours to server timezone if different

Step 2: Configure the Parameter ๐Ÿ“Œ

  1. ๐Ÿ” Log in to VOS3000 Client
  2. ๐Ÿ“Œ Navigate: Operation management โ†’ Softswitch management โ†’ Additional settings โ†’ Server parameter
  3. ๐Ÿ” Locate SERVER_QUERY_CDR_DENY_TIME
  4. โœ๏ธ Enter the comma-separated hour values (e.g., 18,19,20,21,22,23)
  5. ๐Ÿ’พ Save and apply the configuration

Step 3: Verify Blackout Enforcement โœ…

๐Ÿ” After configuration, verify that the blackout is working correctly:

  1. ๐Ÿ• Wait until a configured blackout hour
  2. ๐Ÿ“Š Attempt to query CDR records through the VOS3000 Client
  3. โœ… Confirm that the query is denied with a restriction message
  4. ๐Ÿ• After the blackout window ends, verify that CDR queries are restored

๐Ÿ”— The CDR query blackout works alongside several other CDR access control parameters that together form a comprehensive data protection strategy: ๐Ÿ“‹

ParameterDefaultPurposeComplements Blackout?
SERVER_QUERY_CDR_DENY_TIMENoneBlocks CDR queries during specified hours๐Ÿ”‘ Core parameter
SERVER_QUERY_CDR_MAX_DAY_INTERVAL31Limits CDR query date range to 31 days maxโœ… Prevents heavy queries outside blackout

SERVER_QUERY_MAX_SIZE30000000Total data query limit (items)โœ… Prevents runaway queries
SERVER_QUERY_ONE_PAGE_SIZE10000Default records per pageโœ… Standard pagination control

๐Ÿ’ก Layered protection strategy: For maximum database protection, combine the VOS3000 CDR query blackout with the date range limit (SERVER_QUERY_CDR_MAX_DAY_INTERVAL) and query size limits. The blackout prevents access during critical processing hours, while the date range and size limits prevent excessively heavy queries at any time. This layered approach ensures that even when queries are permitted, they cannot consume excessive resources. For the date range limit configuration, see our CDR query date range guide. ๐Ÿ”—

๐Ÿ›ก๏ธ Common VOS3000 CDR Query Blackout Problems and Solutions

โŒ Misconfigured blackout settings can cause either insufficient protection or unexpected access denial. Here are the most common issues: ๐Ÿ”

โŒ Problem 1: CDR Queries Still Allowed During Blackout Hours

๐Ÿ” Symptom: Users can still query CDR records during the configured blackout hours.

๐Ÿ’ก Cause: The parameter value may contain formatting errors, or the configuration may not have been properly applied after saving.

โœ… Solutions:

  • ๐Ÿ”ง Verify the parameter value uses correct comma-separated format (e.g., 18,19,20 โ€” not 18-20 or 6pm-8pm)
  • ๐Ÿ“Š Ensure there are no spaces in the parameter value
  • ๐Ÿ”„ Re-apply the configuration and restart the softswitch service if necessary
  • ๐Ÿ• Confirm you are testing during the correct hours based on the server timezone

โŒ Problem 2: Blackout Applied in Wrong Timezone

๐Ÿ” Symptom: CDR queries are blocked at unexpected times โ€” not during your intended window.

๐Ÿ’ก Cause: The SERVER_QUERY_CDR_DENY_TIME operates on the server’s system clock timezone, which may differ from your local timezone. If the server is configured in UTC and you specified hours in your local timezone, the blackout window will be offset.

โœ… Solutions:

  • ๐ŸŒ Check the server timezone: date or timedatectl on the VOS3000 Linux server
  • ๐Ÿ”„ Convert your desired blackout hours to the server’s timezone
  • ๐Ÿ“‹ Update the parameter with the corrected hour values
  • ๐Ÿ• Verify by testing a query during the intended blackout window

โŒ Problem 3: Resellers Unable to Access CDRs During Business Hours

๐Ÿ” Symptom: Resellers complain they cannot check their CDRs during normal working hours.

๐Ÿ’ก Cause: The blackout window is set too broadly, covering business hours in addition to billing run periods. This is common when operators set the blackout for the entire evening without narrowing it to the actual billing processing window.

โœ… Solutions:

  • โฑ๏ธ Narrow the blackout window to only the hours when billing runs actually occur
  • ๐Ÿ“Š Schedule billing runs during the lowest-traffic period (typically late night or early morning)
  • ๐Ÿ“‹ Communicate the blackout schedule to all resellers in advance
  • ๐Ÿ”„ If resellers need CDR access, provide them with the CDR text file backup or real-time forwarding as an alternative

โŒ Problem 4: Blackout Not Preventing Heavy Queries Outside Blackout Hours

๐Ÿ” Symptom: Database performance degrades from heavy CDR queries that run outside the blackout window.

๐Ÿ’ก Cause: The VOS3000 CDR query blackout only restricts access during specified hours. Outside those hours, users can still run very large queries that impact performance.

โœ… Solutions:

  • ๐Ÿ“… Set SERVER_QUERY_CDR_MAX_DAY_INTERVAL to limit query date ranges (default: 31 days)
  • ๐Ÿ“ฆ Reduce SERVER_QUERY_MAX_ONE_PAGE_SIZE to limit result set sizes
  • ๐Ÿ“Š Monitor slow queries in the database and identify the heaviest users

โ“ Frequently Asked Questions

โ“ What is the default value for SERVER_QUERY_CDR_DENY_TIME?

๐Ÿ“‹ The default value is None (not configured), which means there is no CDR query blackout โ€” all users can query CDR records at any time. To enable the VOS3000 CDR query blackout, set the parameter to a comma-separated list of hours (0โ€“23) when queries should be blocked. For example, 18,19,20,21,22,23 blocks CDR queries from 6 PM to midnight each day. ๐Ÿ”ง

โ“ Does the VOS3000 CDR query blackout apply to all users?

๐Ÿ”’ Yes. The SERVER_QUERY_CDR_DENY_TIME parameter applies at the server level, which means it blocks CDR queries for all users โ€” including administrators, agents, and resellers. There is no per-user or per-role exemption. During the blackout hours, no one can query CDR records through the VOS3000 Client or web interface. If you need differentiated access control, consider using the VOS3000 Web API with custom application-level access controls. For Web API details, see our VOS3000 Web API account management guide. ๐Ÿ”—

โ“ Can I configure different blackout windows for different days of the week?

๐Ÿ“… No. The VOS3000 CDR query blackout applies the same hours every day. The SERVER_QUERY_CDR_DENY_TIME parameter does not support day-of-week differentiation โ€” if you set 18,19,20, CDR queries are blocked from 6 PM to 9 PM on Monday through Sunday. If you need different schedules for weekdays vs weekends, you would need to manually change the parameter value, or implement a custom automation script that updates the parameter on a schedule. ๐Ÿ”„

โ“ How does the VOS3000 CDR query blackout interact with automated reports?

๐Ÿ“Š The VOS3000 CDR query blackout restricts manual CDR queries through the client and web interfaces. Automated report generation (configured under Navigation โ†’ Report management) may operate independently of the blackout restriction since reports are generated by the system internally rather than through the query interface. However, if automated reports rely on the same query mechanism, they may also be affected. Always test your report generation schedule against the blackout window to ensure reports can complete successfully. For report configuration, see our billing system overview. ๐Ÿ“‹

โ“ What happens when a user tries to query CDRs during the blackout?

๐Ÿšซ When a user attempts to search or view CDR records during the configured blackout hours, the VOS3000 system denies the query and displays a restriction notice. The user is informed that CDR queries are not available during this time period. No partial results are returned. The query does not execute at all โ€” it is blocked before reaching the database, ensuring zero impact on database performance during the blackout window. ๐Ÿ”’

โ“ Can I temporarily disable the blackout for emergency CDR access?

๐Ÿ”ง Yes. To temporarily disable the VOS3000 CDR query blackout, set the SERVER_QUERY_CDR_DENY_TIME parameter to empty (None) and save the configuration. This immediately restores CDR query access for all users. After the emergency access is no longer needed, re-enter the blackout hours and save again. Remember to re-enable the blackout promptly to maintain database protection during billing runs. For help managing VOS3000 parameters, contact our team at WhatsApp: +8801911119966. ๐Ÿ’ฌ
