The system generates a record at the end of a call or each call leg. It attempts to send the record at the time it is generated. However, if not possible, it buffers records up to the limit set for the system. By default that is 500 records.

• Whilst buffering, it still attempts to send a record when that new record is generated. If successful, it will also send any buffered records.

• If the buffer limit is reached, the system deletes the oldest record each time a new record is added. The buffer is maintained through system restarts.
