CDR-Stats is a free and open source call detail record analysis and reporting software for Freeswitch, Asterisk and other types of VoIP Switch. It allows you to interrogate CDR to provide reports and statistics via a simple to use powerful web interface.

It is based on the Django Python Framework, Celery, Gevent, PostgreSQL and InfluxDB.


  • Highly scalable design to maintain high performance when analysing large quantities of data.
  • Single and Multi-server architectures to allow reporting on many millions of calls from multiple call data sources.
  • Browser Responsive - The pages resize to suit any browsing device so CDR-Stats can be managed from a phone browser, tablet or computer.
  • Alarms – Custom alarm triggers can be set for a range of conditions including average length of calls, failed calls, and unexpected destinations called.
  • Realtime Reporting of calls in progress on supported platforms.
  • Fraud detection - Using graphical tools helps spot patterns which may indicate suspicious or fraudulent activity.
  • Multi-tenant System that allows CDR from multiple sources or CDR assigned to customers on the basis of account-code.
