The <strong>VOS3000 CDR query date range<\/strong> limit, controlled by <strong>SERVER_QUERY_CDR_MAX_DAY_INTERVAL<\/strong>, 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 \u2014 but understanding how to work within and around this limit is essential for every VOS3000 operator. \u23f1\ufe0f<\/p>\n\n\n\n<p>\ud83d\udd27 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. \ud83d\udccb<\/p>\n\n\n\n<p>\ud83d\udcac Need help optimizing your VOS3000 CDR query performance?

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 \u2014 but consider the performance implications carefully, especially on high-traffic systems. \ud83d\udd27<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-can-i-increase-the-vos-3000-cdr-query-date-range-to-365-days\">\u2753 Can I increase the VOS3000 CDR query date range to 365 days?<\/h3>\n\n\n\n<p>\u26a0\ufe0f 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 \u2014 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. \ud83d\udcca<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-does-the-date-range-limit-apply-to-the-cdr-text-file-export\">\u2753 Does the date range limit apply to the CDR text file export?<\/h3>\n\n\n\n<p>\ud83d\udcc4 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. \ud83d\udd17<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-how-do-i-export-more-than-31-days-of-cdr-data-for-a-reseller\">\u2753 How do I export more than 31 days of CDR data for a reseller?<\/h3>\n\n\n\n<p>\ud83d\udcca You have several options: (1) Use incremental queries \u2014 run multiple 31-day queries and merge the results externally, (2) Access the CDR text files on the server directly \u2014 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. \ud83d\udca1<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"\u2753-does-the-vos-3000-cdr-query-date-range-limit-affect-automated-reports\">\u2753 Does the VOS3000 CDR query date range limit affect automated reports?<\/h3>\n\n\n\n<p>\ud83d\udccb 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&#8217;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.

Together, these parameters provide layered protection against heavy queries.
