# Configure CDR

This procedure describes how to set the configuration options in CDR Configuration Menu. If you perform this procedure when you set up CDR for the first time, you do not have to do it again unless you need to change a setting.

Note: If you want to reduce the number of CDR records stored, you must first stop CDR if it is running.

To configure CDR:

1. From the Main menu, select (R) Reports and then (A) Call Detail Recorder and then (A) Configure Menu.

2. Select (A) Configure Menu.

3. Do one of the following:

   - To enable all lines, select (A) Enable all lines and then enter Y.

   - To enable individual lines, select (B) Enable individual lines and enter the line triplet that represents the line to add.

4. Select (E) Call Types and enter one of the following:

   - A for all call types

   - A single call type number (1-28), for example, 4.

   - A range of call types, for example 1-20.

   - A comma-separated list of call types, such as 1,3,5,7.

   - A combination of ranges and list, for example 1-4,6,7-9,12.

   - ? for a list of call types and their definitions.

5. Select (F) Max number of CDR msgs and enter a number of CDR records (messages) to store (1-999999).

   - CDR records are stored in blocks of 64 records. It is recommended that you choose a number that is divisible by 64, to maximize disk storage efficiency.

   - If you reduce the number of CDR records stored, the area committed to disk storage is not reduced until you delete the records. If you increase the number of records, disk storage changes when you exit the CDR Configuration Menu.

   - You must leave a minimum of 300 accounting records in order to run the NuPoint Voice application. You are not permitted to leave fewer records than this.

6. Select (H) Max delay to write CDR records to diskand enter the delay in seconds (10-600). CDR records are buffered as they come in, and written to disk as the buffer fills. The larger the delay, the fewer disk write operations are performed. This increases the possibility that you could lose some data in the event of a server failure. It is recommended that you not reduce this parameter below the default of 180 seconds.

7. Exit the CDR configuration menu to save your choices. If you reduced the number of CDR messages stored, you must Delete CDR messages first.
