Anti-DDoS for VoIP: CIRPACK Session Border Controller


The Cirpack session border controller (SBC) creates a demarcation point between two VoIP-based networks. It allows control of signalling and media streams. The Cirpack SBC offers the required security mechanisms for service providers, such as:
  • Protection from fraudulent access
  • Protection from fraudulent use of services (DoS/DDoS attacks)
  • Concealment of network topologies
  • Media pinholing – targeted media guidance and control
  • Transcoding
  • Encryption
  • Header manipulation
It also ensures call control and checks approved media streams.
