Please follow this illustrated guide to delete historic calls from the system
Login to Voicesafe with an administrator account and click on the Admin tab
In here click on Features Configuration
In Features and Configuration select the Deletion tab
In this screen you'd click the Yes radio button to enable schedule and select option 1 or 2
1. Recoding only this will only delete the mp3's
2. Recordings and Call Data Records will delete BOTH the MP3's AND the database entry
Basically option one frees up hard drive space, but they still have a record of the call in the GUI
option 2 deletes every mention of the call.
In this Screen click Delete Backup checkbox and from the dropdown select the older than months calls you'd wish to delete and click save.
The system will now delete calls for the desired setting until you disable the schedule .
