The benefits of CDR is to control call management  expenses used by accounting 

departments in an organization for both local and long distance calls, and to monitor calls usage for the benefit of  the organization to ensure your employees are not making too much personal calls.

In PBXs Call Detail records are the output data by a serial link  port called Station Message Detail Recording Port(SMDR) which tracks all the incoming and outgoing calls for each extension. These data are available at the end of the call or in some PBXs these data appear during the call.
