SBC session border controllers 7
1 INTRODUCTION
Session Border Controller (SBC) is designed for heterogeneous VoIP network interfacing tasks, ensuring
interoperability of terminals with different signaling protocols and codec sets in use. In addition, due to the
functionality of Firewall, NAT and proxying signal and media traffic, it protects the corporate network from attacks
and hides its internal structure. SBC is always installed at the edge of the corporate or carrier VoIP network and
performs those functions that it is not reasonable to entrust to the operator's devices (for example, a flexible
Softswitch).
Main SBC functions
– protecting the network and other devices from external attacks (e.g. DoS attacks);
– Firewall functions;
– hiding carrier's network topology;
– negotiating different alarm protocols and codecs;
– providing QoS services and stream prioritization;
– communicating with devices connected via NAT (Network Address Translation);
– collecting statistics on the calls served through SBC.
2 DEVICE DESCRIPTION
2.1 Purpose
Eltex SBC is a component of the ECSS-10 hardware and software complex, which participates in the call service
process as a session border controller. The device provides normalization of the signal protocol implementations,
the set SLA level of quality, protection of the carrier's network from unauthorized access and various attacks,
collection of statistics.
