Session border controller SBC-1000

Mass production
Key features
  • Up to 500 simultaneous calls
  • Business process security
  • Efficient management
  • Hardware redundancy
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
Features
  • Ensuring security for service provider networks
  • Public IP addresses translation
  • Flexible distribution of redundancy routes
  • Extended Firewall settings
  • Statistics gathering
  • Media streams transcoding1
  • Alarm log
  • Linear scaling1
  • RADIUS access control
  • Operation with subscribers behind NAT
  • SDP analysis and verification
  • End-to-end SLA1
  • Dynamic firewall
  • RTCP control
  • RTP sessions management
  • Efficient management
  • Black and white lists
  • Quality of Service (QoS)1
  • Integration with Eltex.EMS
  • Signaling protocol conversion1
  • Load balancing between trunks
  • Trunks with registration
  • Flexible calls distribution according to established rules
  • 1+1 redundancy1
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 terminal devices that have non-intersecting codec packs1 and different SIP versions and extensions.
