An SBC or session border controller is a unique technology that helps enable and secure vital parts of a business’s telecommunications infrastructure. Commonly, it controls networks by either admitting or not admitting besides the directing communications that happen between a couple of end devices present on the network, and these kinds of communications are known as sessions. The session border controller accomplishes this session by controlling a point where the traffic is handed from and off from one network to another network, known as the border. As SBCs fit well in a network, both businesses and service providers implement them to their hearts’ content.
The job of the session border controller
AudioCodes session border controller does the following:
Enabling SIP trunking
You will find the AudioCodes session border controller to be a vital component of all SIP trunking solutions. The job of the SBC is to observe all sessions that cross between the external ITSP network and the internal enterprise network. SBC also finds out where the session ought to be routed besides the priority at which a session gets assigned if the network is busy. It also determines the amount of bandwidth that must be assigned to each session according to network utilization and the policies that have been formed for the network. Hence, it can be said that the SBC carries on SIP interworking. It permits a device that uses different variations of SIP to communicate with each other efficiently and effectively.
Security and protecting the network
The chief job of the SBC is securing and protecting the network. It is developed from the ground and goes up to eliminate spoofing attacks, toll fraud, and denial-of-service attacks. Its job is also to secure the network by not exposing the architecture. Thus, it makes it tougher for fraudsters to get access to the vulnerable portions of the network. The SBC also enables encryption that prevents communications from getting tampered with or intercepted unlawfully.
Session traffic cop
Essentially, the SBC protects the VoIP network present in a service network provider or an enterprise. When it does this job, it carries on session admissions control. A session admissions control determines who has access to the network. Hence, the SBC is the gatekeeper of the VoIP network. This way, it keeps the VoIP highways organized and safe. The SBC creates and accesses three lists, namely greylists, blacklists, and whitelists.
Connect with protocol translation and topology hiding
The session border controller never fails to provide a seamless experience when the matter zeroes on interworking and interconnecting between various protocols and networks that run over them. The SBC translates between the variants of SIP. Hence, calls get through all of them intact. Additionally, as various VoIP solutions utilize different audio codecs that are not supported completely on the sides of a session, the SBC changes protocols on the fly. Hence, the SBC has been formed to eliminate multiple things. Try the best ways and right option to have all the benefits.
