Session Border Controller: Protecting Business Telecommunications

Important components of a company’s telecommunications infrastructure can be enabled and secured with the use of a special technology called a session border controller, or SBC. In addition to directing communications between a few end devices on the network, which are referred to as sessions, it typically regulates networks by admitting or refusing to admit. By managing a point known as the border—where traffic is handed over and on from one network to another—the session border controller completes this session. SBCs are widely used by both companies and service providers because they perform well in networks.

The session boundary controller’s duties

What is done by the AudioCodes session border controller?

Making SIP trunking active

For every SIP trunking solution, the AudioCodes session border controller is an essential part. All sessions that move between the internal enterprise network and the external ITSP network must be observed by the SBC. If the network is congested, SBC determines not only the priority at which a session is assigned, but also the appropriate route for the session. Additionally, based on network utilisation and established network restrictions, it establishes the necessary bandwidth allotment for each session. As a result, SIP interworking is carried on by the SBC. This enables efficient and effective communication across devices that implement different SIP versions.

Safeguarding and protecting the network

The SBC’s main responsibility is to safeguard and secure the network. To combat denial-of-service attacks, toll fraud, and spoofing, it is built from the ground up. By preventing the architecture from being revealed, it also serves to safeguard the network. It therefore makes it more difficult for fraudsters to gain access to the network’s weak points. Moreover, the SBC permits encryption, which guards against illegal interception and tampering with messages.

A traffic cop in session

The VoIP network that is part of a service network provider or business is essentially protected by the SBC. It maintains control over session admissions while performing this task. The network’s access is controlled by a session admissions control. Thus, the VoIP network’s gatekeeper is the SBC. In this manner, it maintains the VoIP roads’ safety and organization. Three lists are created and accessed by the SBC: whitelists, blacklists, and greylists.

Interconnect with topology concealing and protocol translation.

When it comes to facilitating the interconnection and operation of different protocols and networks that utilise them, the session border controller consistently delivers a flawless experience. All of the SIP variations are translated by the SBC. Therefore, calls pass through each one of them undamaged. The SBC also adapts to changing protocols because different VoIP solutions use different audio codecs that aren’t fully supported on both sides of a session. Thus, the SBC was established in order to get rid of a lot of things. To reap all the rewards, try the best options and methods.
