eRecorder HD High Level Network Architecture
A “Tenant” refers to an Enterprise customer of the (M)NO or even a residential (Mobile) User subscribed to the Voice Recording service as offered by the Operator. Configurable Retention Periods per Tenant are possible and Tenant Data is isolated in Authentication Zones.
Multi-media Cloud Recording
The eRecorder HD supports recording of mobile phone and/or fixed line telephone- conversations, the architecture of the system is such that other media types such as SMS, MMS or Video can be optionally added.
Performance, Scalability & Small Footprint
A critical component of the eRecorder HD is the Capture Engine: the recording & encryption module that combines high performance with a small footprint.
The Capture Engine’s main task is instant recording, in-memory strong encryption and fingerprinting of all calls. One Capture Engine supports up to 2,650 concurrent call recordings installed on standard enterprise grade COTS hardware (HDD storage), or up to 10,000 concurrent call recordings when equipped with high-performance SSD storage technology.
Software Defined Object Storage
The Storage Center forms an integral part of the eRecorder HD to either temporarily buffer (e.g. 2-3 days) or store for a longer period of time (months, years) encrypted call recordings on behalf of the Enterprise.
The Storage Center is based on “software-defined object storage” to be able to manage objects in a flat address space and making it easy to scale-up storage capacity (G/T/P Bytes). In addition, erasure coding is used as a (additional) method of data protection in which data is broken into fragments that are expanded and encoded with a configurable number of redundant pieces of data and stored across different locations, such as disks, storage nodes or geographical redundant.
SIPREC Recording Interface
The eRecorder HD supports the SIPREC protocol towards the IMS / MRF or SBC in the network of the (M)NO. SIPREC is an IETF standards based protocol to manage delivery of media in SIP-based systems.
Highest Security Standards
The eRecorder HD provides in-memory strong encryption and fingerprinting of all calls. Every call is encrypted with an unique data-encryption-key and decryption is only possible by the Customer.
The eRecorder HD performs in-memory strong a-symmetric encryption (RSA2048) on all calls, with a unique data-encryption-key per call, and fingerprinting (SHA 256) in order to proof the recording is authentic.
Encrypted call recording files are transferred over a secure link to the on-premise Decryption Service and calls are decrypted with the key only known by the Customer. Integration between the Decryption Service and the Customer network-based HSM (FIPS Level 140-2, L2/L3) is available as an option.
