The Call Details Recording (CDR) interface enables developers to design and build solutions that can retrieve and manage the CDR data files produced by Avaya Aura Session Manager. When the CDR feature is administered on a Session Manager server, Session Manager saves its CDR records to the server's hard drive. Client applications can periodically log on to the Session Manager server and retrieve the CDR data files that are available.

Session Manager XML format (introduced in Session Manager Release 6.3 Service Pack 4) provides enhanced call records and enables existing CDR client applications to easily adopt any future changes in the CDR formats.

The CDR data files produced contain two types of data records:

• Date Records: A timestamp in the CDR data file indicating to the client CDR processing application that every call record that follows in the file refers to the new date.
• Call Detail Records: Each call detail record contains data about a particular call, including:
  • Time of call
  • Duration of call
  • Dialled and calling number
  • Bandwidth
  • Call condition: extremely long duration, tandem call, call from a SIP phone
  • Originating and terminating SIP entities
  • Calling and called party IP address

All data contained in the CDR data files is stored in standard ASCII characters.
