All About CDR Records

Call Detail Record (CDR)

• SOAP/HTTPS-based interface
• Allows third-party billing applications or customers to query the Cisco Unified CM. CDR repository node to retrieve files on demand through the use of two API calls, get_file_list and get_file
• CDR records are stored as flat files
• CDRs are obtain in a two-step process:
Application requests CDR file lists based on a specific time interval
Then, it can request specific CDR files from those lists that are returned via a SFTP session
• Returns a list of files that match a specified time interval (get_file_list)
• Returns a specific file that matches a specified filename (get_file)
• Limit of 1300 file names get returned from the get_file_list API
• Specified time range cannot span over one hour
• Service not available during CDR repository file maintenance window
• CDR files are sent via standard FTP or (s)FTP, which is User configurable
• get_file can return only one file per request
• Servlet needs to be activated through service activation page
• The following service parameters apply to CDRs:
• CDR Enabled Flag—Cisco CallManager service parameter that controls whether CDRs are generated. Set this parameter on each Cisco Unified Communications Manager in the cluster. You do not need to restart the Cisco Unified Communications Manager for the change to take effect.
• CDR Log Calls With Zero Duration Flag—Cisco CallManager service parameter that controls whether calls with zero duration are logged in CDRs. The default specifies False (zero duration calls not logged).
• Call Diagnostics Enabled—Cisco CallManager service parameter that controls whether call diagnostic records that contain QoS information about calls are generated. The default specifies False (diagnostics not generated).
• The following enterprise parameters apply to CDRs:
• CDR File Time Interval—The parameter that determines how many seconds to write to a CDR file before Cisco Unified Communications Manager closes the CDR file and opens a new one.
