CDR Data Storage
In the event of a WAN outage, local CDR data is stored for up to two hours on the device (such as a
DVS, voicemail-enabled switch, or service appliance). When WAN connectivity is restored, the stored
data is forwarded to the Headquarters database. After two hours, the distributed server deletes the
data and logs an error to the NT event log.
