Session border controller

Eltex SBC is an element of VoIP network that participates in call processing as a session border controller. The device provides signal protocol normalization, statistics collection and network protection against unauthorized access and attacks.
 

Application

Eltex SBC is deployed at the border of the IP networks:
 

• between service providers’ networks;
• between service provider network and Customer’s corporate network;
• between service provider network and a public network

Bypassing NAT

NAT bypassing is a necessary feature that provides transparent transmission of voice and video traffic over IP networks. Different types of NAT are supported.
 

Security

Eltex SBC provides network protection against unaut-horized access and DoS attacks. Intellectual access management, ingress load limiting and network topology hiding ensure security of a network.
 

Network topology hiding

Eltex SBC allows providing access to a carrier or corporate network from an untrusted connection, ensuring security of a Company business data.
 

The following mechanisms are used:
 

• intellectual IP addresses translation for signalling and media traffic;
• full B2BUA provides a required network isolation level.
   

Redundancy

Complete redundancy is ensured by the cluster redundancy scheme and presence of backup power modules.
 

Interconnection

Eltex SBC provides the opportunity of interaction between 2 terminal devices that have non-intersecting codec packs and different SIP versions and extensions.
