Appendix C - CDR Fields, Unformatted
File
The CDR (Call Detail Records) utility is used to retrieve conference information to a file. The CDR utility can
retrieve conference information to a file in both formatted and unformatted formats.
Unformatted CDR files contain multiple records. The first record in each file contains information about the
conference in general, such as the conference name and start time. The remaining records each contain
information about one event that occurred during the conference, such as a participant connecting to the
conference, or a user extending the length of the conference. The first field in each record identifies the
event type, and this is followed by values containing information about the event. The fields are separated
by commas.
Formatted files contain basically the same information as unformatted files, but with the field values
replaced by descriptions. Formatted files are divided into sections, each containing information about one
conference event. The first line in each section is a title describing the type of event, and this is followed by
multiple lines, each containing information about the event in the form of a descriptive field name and value.
The MCU sends the entire CDR file via API or HTTP, and the Collaboration Server or external application
does the processing and sorting. The Collaboration Server ignores events that it does not recognize, that
is, events written in a higher version that do not exist in the current version. Therefore, to enable
compatibility between versions, instead of adding new fields to existing events, new fields are added as
separate events, so as not to affect the events from older versions. This allows users with lower versions to
retrieve CDR files that were created in higher versions.
The Conference Summary Record
The conference summary record (the first record in the unformatted CDR file) contains the following fields.
The field names and values in the formatted file will appear in the language being used for the
Collaboration Server Web Client user interface at the time when the CDR information is retrieved.
The value of the fields that support Unicode values, such as the info fields, will be stored in the CDR
file in UTF8. The application that reads the CDR file must support Unicode.
This appendix describes the fields and values in the unformatted CDR records.
Although the formatted files contain basically the same information, in a few instances a single field in
the unformatted file is converted to multiple lines in the formatted file, and in other cases, multiple
fields in the unformatted file are combined into one line in the formatted file.
