Topology hiding: 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)
  • Hides network topologies
It also ensures call control and checks approved media streams.
