The licensing model for CallRex is based on a per user basis; therefore you must assign a license to each user and administrator.

Each CallRex license allows you to monitor and record the user’s phone activity.

A Companding Algorithm is an International Telecommunications Union (ITU) standard for converting analog data into digital form using Pulse Code Modulation (PCM). Europe and Latin America uses A-Law, while North America and Japan use mu-Law (µ-Law).
By default, the µ-law (Default; North America, Japan) option is selected. If the users are from Europe or Latin America, then select the A-law (Europe, South America, Asia) option.
Call Retention allows you to delete unwanted calls, like calls that are less than a specific duration or calls that are older than specific time period. This is useful to save space on hard disk.
The Delete recorded calls less than X seconds option allows you to delete calls less than a specified length of time. These calls are not saved to the system. This change is effective from the time you enter the value. The calls recorded earlier are not deleted.
The Delete recorded calls older than X days option allows you to delete calls older than the specified number of days. This deletion takes place 24 hours after you first enter any value into this field. If you enter 0 in this field, calls are not deleted.

The Schedule System Maintenance allows the user to select a time to schedule maintenance for better performance of the system. When CallRex customers have problems with service stability or unconverted RAW files, the support engineer has to set up a process that is referred as Scheduled Maintenance. In the past, Scheduled Maintenance involved setting up a scheduled windows task that restarts all the CallRex services and converts any unconverted RAW files by executing a batch script. With the introduction of this new feature, scheduled maintenance is an integrated part of the product and is easily available from the CallRex Client user interface.
The user can specify a day and time on a daily or weekly basis to run the system maintenance.
To configure the system maintenance:
- Select the Enable Scheduled Maintenance check box.
- Select the Daily at option and set the time to run the system maintenance on a daily basis.
- Select the Weekly on option and set the day and time to run the system maintenance on a weekly basis.
The Multi-Media Settings allow configuring inactivity time out and profile refresh time for the multi-media agent deployed at client machine. This is only useful if you have purchased CallRex Computer Recording license.
