Method and apparatus for fail-safe control of recordings

A system for fault-tolerant recording of a plurality of calls conducted concurrently at a telephonic exchange equipment, comprising:

• a telephonic exchange equipment;
• a plurality of communication integration devices connected to the telephonic exchange equipment for supplying metadata of calls of the telephonic exchange equipment;
• a plurality of computerized apparatuses corresponding to the plurality of the communication integration devices where each of the computerized apparatuses is connected to one of the communication integration device for receiving the metadata of the calls and configured to generate unique identifiers of the calls that are commonly structured between the plurality of the computerized apparatuses regardless of the differences in the metadata supplied by the plurality of communication integration devices;
• a recorder device connected to the telephonic exchange equipment by a data link for receiving contents of the calls, and further connected to the plurality of the computerized apparatuses;
• the system configured such that when the contents of the calls of the telephonic exchange equipment is transferred to the recorder device, correspondingly the plurality of the communication integration devices supply metadata of the calls to the plurality of the computerized apparatuses connected thereto, and
• the system is further configured such that a first computerized apparatus of the plurality of the computerized apparatuses controls recording of the contents of the calls by the recorder device while assigning the unique identifiers of the calls to the recorder device, wherein the recorder device is configured to provide feedback of activities thereof to the plurality of the computerized apparatuses, and wherein the feedback comprises the assigned unique identifiers of the calls, and
• in case the first computerized apparatus of the plurality of the computerized apparatuses fails, a second computerized apparatus of the plurality of the computerized apparatuses is activable to maintain, based on the supplied metadata and the feedback from the recorder device that comprises the assigned unique identifiers of the calls, recordings of the calls that were controlled by the first computerized apparatus, thereby sustaining recordings of the recorder device regardless of a failure of the first computerized apparatus.
