 Target market
 -------------
 
 The main goal of CDRTool is to provide a carrier grade mediation and rating
 engine for service providers deploying OpenSIPS as SIP Proxy/Registrar.
 
 CDRTool is a mature product with +20 years in production and has been
 used in environments with tens of millions of CDRs per month.
 
 
 Features
 --------
 
 CDRTool allows real-time web access to Call Details Records generated by
 OpenSIPS radius accounting and sip trace modules. The information can be
 combined with media information logged by MediaProxy while a separate
 OpenSIPS module can display complete messages of all SIP messages the enter
 and exit the SIP Proxy. CDRs can be filtered and statistics can be built in
 real-time to summarize service usage based on various criteria.
 
 Multiple users can share the CDR search criteria and the query results.
 Ticket numbers can be linked to sets of Call Details Records. Queries and
 results can be replayed later to reproduce an exiting or a previous problem.
 This feature allows fast communication and troubleshooting when multiple
 departments work together to find a resolution for a problem and communicate
 it with the customer.
