Voice recording storage

With Red Box, you have a comprehensive, flexible solution for storing voice recordings. Each recorder equipped with NAS archive capability can archive calls to any network storage media (such as EMC Centera) in real time or at scheduled intervals. The system administrator can configure these schedules; the system will maintain event logs and audit trail, and provide alarms according to schedule adherence and completeness of data transfers.

The solution offers direct management of the storage process. It eliminates the need for additional software or servers and offers extensive functionality to deliver flexibility in:

• Duplicated storage (same data to more than one location)
• Differentiated storage offering data differentiation based on the business or retention requirement, (such as different data stored in different locations for different retention periods)

In this way, it provides total compliance with retention and storage policies.

Intelligent management

The voice recorder records all calls to its local hard disk drive, which it uses as a cache or temporary storage area for all voice recordings. Archiving is a managed process, providing complete secure transfer of data to network devices.

In the event of a network failure during a NAS archive schedule, the system will wait for the network to become available and continue, without loss of data or replication of data transfer. If the transfer cannot complete within the remaining scheduled time, the system will raise alarms and SNMP notifications to the administrator and generate log entries for the incomplete transfer and initial network failure. If left unattended the system will automatically catch up during the next scheduled transfer. Should the backlog become excessive (beyond a configured watermark of ‘un-archived data’), the system will automatically alarm and notify the administrator and allow for intervention or adjustment to the archive schedule.

Archive groups

You can configure the Red Box recording system into archive groups. Each group can be configured using any given database parameter, allowing system groups for telephony details stored in the system; Extension, Device, CTI details or annotated/appended data from other forms of integration. These groups can be configured for retention periods, allowing the system automatically to manage the data for that group. Once the data exceeds the limits set for the group, old data exceeding the limits is automatically deleted. The system can manage an unlimited number of groups.

A true, authenticated record

The Red Box voice recorder stores calls to multiple compression algorithms including G729a (8 Kbits/second = 3.4 Mb per hour). Calls stored in the voice recorder’s architecture are a complete, authenticated record of the original communications. This offers a legally-admissible reproduction of events. Recordings include any silence (quiet periods of a communication) and are stored locally and on archive media to provide a true representation of calls throughout the solution. To remove any silent periods would mean that the call is not a true reflection of the original communication and would not stand up to examination in court. This type of processing would also mean ‘authentication’ (digital water-marking) of calls would be invalidated. Red Box does not suppress or alter recordings; they are therefore a true representation of the call was recorded. On playback it is possible to suppress the silence to review, analyse or export recordings. This does not alter the integrity of the original call recording or affect its authenticity.

Secure deletion

Our automated retention process manages the duration for which calls are stored in the voice-recording architecture. Once a call or group of calls is marked for deletion, all instances are deleted from all areas of the system, including local HDD and network storage.

Calls are securely deleted from the whole solution. As a result of our ‘frame-based’ recording technology and the way files in which are written, deletion removes all trace of the call’s existence, making it unrecoverable. This means, of course, that retention policies must be carefully maintained.
