This means that CDR file rotation is not active by default. You must explicitly set a value between 60 and 86400 seconds and enable SS_CDR_RECORD_TO_FILE to On before the system generates backup CDR text files. Without this configuration, CDR records are only stored in the database. \ud83d\udca1<\/p>\n\n\n\n\u2753 How does VOS3000 CDR file rotation prevent disk overflow?<\/h3>\n\n\n\n\ud83d\udee1\ufe0f The VOS3000 CDR file rotation uses SERVER_CDR_FILE_WRITE_MAX to enforce a maximum number of retained files. When the file count exceeds this limit, the oldest files are automatically deleted. For example, with the default value of 2048 and an hourly interval, the system retains approximately 85 days of CDR files. Once the 2049th file is created, the oldest file is removed, maintaining a consistent disk footprint. This sliding window mechanism ensures the CDR directory never grows beyond a predictable size. \ud83d\udcc1<\/p>\n\n\n\n \u2753 Can I change the VOS3000 CDR file rotation interval without restarting?<\/h3>\n\n\n\n\ud83d\udd27 Server parameters in VOS3000 typically take effect after saving and applying the configuration through the VOS3000 Client interface. While some parameters may apply immediately, it is recommended to verify that the new interval is in effect by checking the timestamps of newly created CDR files. If the old interval persists, a softswitch service restart may be required. Always test configuration changes during a maintenance window to avoid any disruption to CDR recording. \ud83d\udcca<\/p>\n\n\n\n \u2753 What is the relationship between SS_CDR_RECORD_TO_FILE and SERVER_CDR_FILE_WRITE_INTERVAL?<\/h3>\n\n\n\n\ud83d\udd17 SS_CDR_RECORD_TO_FILE<\/strong> is the master switch that enables or disables the entire CDR text file system. SERVER_CDR_FILE_WRITE_INTERVAL<\/strong> controls the frequency of file creation within that system. If SS_CDR_RECORD_TO_FILE is Off (default), no CDR files are generated regardless of the interval setting. If it is On but the interval is not set (None), the system may not create files properly. Both parameters must be correctly configured for the VOS3000 CDR file rotation to function. \ud83c\udfaf<\/p>\n\n\n\n\u2753 How do I include non-connected calls in the CDR text files?<\/h3>\n\n\n\n\ud83d\udcca By default, SS_CDR_RECORD_NONCONNECT<\/strong> is set to Off, which means only successfully connected calls (calls with duration greater than 0 seconds) are written to the CDR text files. To include failed call attempts, busy calls, and no-answer calls, set SS_CDR_RECORD_NONCONNECT to On. Be aware that enabling this parameter significantly increases the number of CDR records per file, especially during traffic spikes or attack scenarios. For DDoS protection guidance, see our zero duration CDR control guide. \u26a0\ufe0f<\/p>\n\n\n\n\u2753 Where are VOS3000 CDR text files stored on the server?<\/h3>\n\n\n\n\ud83d\udcc1 CDR text files are stored in the cdr<\/strong> directory beneath the VOS3000 installation directory. The file naming convention is YYYYMMDDHH.txt<\/strong>, where YYYY is the year, MM is the month, DD is the day, and HH is the hour. Each file contains all CDRs whose end time falls within that time window. For example, 2026042614.txt<\/code> contains CDRs for calls that ended between 14:00 and 15:00 on April 26, 2026. The files use pipe-delimited format with 18 fields per record \u2014 see our CDR pipe format reference for complete field documentation. \ud83d\udccb<\/p>\n\n\n\n\ud83d\udcde Need Expert Help with VOS3000 CDR File Rotation?<\/h2>\n\n\n\n\ud83d\udd27 Proper VOS3000 CDR file rotation configuration is essential for ensuring billing data integrity, meeting regulatory retention requirements, and preventing disk overflow disasters.
