# Raw Switch Data

Class 4 automatically store all PCAPs and CDRs to the local disk.  However, if the local disk is less than 15% free space, Class 4 will stop to terminate calls.  This is done so that Class 4 will not terminate calls if it can't generate CDRs for the billing purpose. 

You can find the CDRs in the following directory:
