Encryption of VoIP data: Cirpack Session Border Controller

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 encryption mechanisms for service providers such as:
  • Encryption of SIP messages between the terminal equipment and SBC
  • Encryption of media streams between the terminal equipment and SBC
It also ensures call control and checks approved media streams.
