CDR File Types
Two types of CDR files exist in the CDR directory on the controller:
- .work — The active file that is being updated by the
accounting system. The file is closed and renamed with the .dat
extension when it attains its maximum size (16 MB) or it has been open for the maximum
allowed duration (12 hours). You can back up and copy the .work
file from the controller to a remote server.
- .dat — The inactive file that contains the archived account
records. You can back up and copy the .dat file from the
controller to a remote server.
Note
The CDR directory on the controller only has two
files — a
.work file and a
.dat file.
When the
.work file attains its maximum size of 16 MB, or it
has been open for 12 hours, it is saved as a
.dat file. This
new
.dat file overwrites the existing
.dat file. If you want to copy the existing
.dat file, you must do so before it is overwritten by the
new
.dat file.
