Posted by gracedervishi in Technology on December 23rd, 2016

Session Border Controller (SBC) is a device which is deployed in the VoIP (Voice over Internet Protocol) networks to mainly control the signaling and the also the media streams which are involved in setting up. This method conducts, tearing down the telephone calls or any other interactive media communication. Earlier the deployments of these SBCs were mainly between two border stations. But as with all technology, this too further advanced. The SBCs took up a new role and expanded to all the border networks now between the service providers’ access network to a backbone network, connecting all the customers and the enterprises together.

Let’s talk about some important functions of the SBCs and see how effective it is.

Security: Protects the network from

  • Topology Hiding
  • Malicious attacks such as “denial-of-service attack” (DoS) and distributed DoS
  • Malformed packet protection
  • “Toll fraud” via rogue media streams

Connectivity: Different parts of networks communicate through

  • VPN connectivity
  • IPv4 to IPv6 interworking
  • NAT Traversal
  • SIP Normalization

Quality of Service: Function includes

  • Rate limiting
  • Call admission control
  • Resource allocation
  • ToS/DSCP bit setting
  • Traffic Policing

Media Services: SBCs provide built in DSPs to offer services such as

  • Media Transcoding
  • Data and fax interworking
  • Tones and announcements
  • Support for voice and video calls

The list of features mentioned above is solely offered by SBCs and nothing beats it as far as communication for your business is concerned. There are also some “Regulatory” provided by SBCs and provides regulatory requirements such as: “Emergency Calls” and “Lawful Interception”.

The success and reputation of SBCs has also earned them the deserved role of SIP to “WebRTC Gateways” and translate SIP, with the advent of WebRTC. The operation of SBCs requires VoIP networks. The SBC simply modifies the stream of call signaling involved in each call and limits the kind of calls that’s can be conducted, changing the codec choices as a result and so on. The other facility of SBCs include allowing the operators to manage the calls that are made on their networks and also fix or change protocols and overcome some of the problems that firewalls and NATs present for VoIP calls.
