Prerecording is the process of recording all calls, while only permanently saving the recordings specified by the phone user. This means that while a call is in progress, or shortly after a call has been completed, the phone user has the ability to save the call recording. If the user does not save the call within this time, the call recording is discarded.
The amount of time the user has to save the call can be adjusted by the system administrator. The default time is 2 minutes.
