A Session Border Controller SBC is a network function which secures voice over IP VoIP infrastructures while providing interworking between incompatible signaling messages and media flows sessions from end devices or application servers. SBCs are employed in Enterprise infrastructures or any carrier network delivering commercial residential, business, fixed-line or mobile VoIP services. They are typically deployed at both the network edge and at carrier interconnects, the demarcation points borders between their users and other service providers.

While historically supporting the many signaling types employed in enterprise networks, such as H. As SIP has been evolving over the last two decades, SBCs are invaluable in providing interworking between disparate protocol versions and optional headers. As mentioned above, SBC is a demarcation or termination point of the SIP trunk connection in your communications network.

Thereafter it determines where to route the session and what priority is necessary to assign to the session when the network is busy. The function also includes determining how much bandwidth is necessary for a session. The network utilization and the policies established for the network determines the amount of bandwidth necessary. In addition to the others, the software performs SIP interworking. This allows devices that subtly seek different variants of SIP to communicate with each other effectively and efficiently.

SBC smoothly performs the inter-working and interconnecting tasks, such as dealing with SIP variants and translating protocols, between different networks and the protocols running over them. SIP has a lot of variants; an SBC software can translate these variants between devices so that the calls get through with all their features intact. SBC performs session admission control which means it inspects and sees who should be allowed to access the network and who should not.

To perform this task, it creates three lists: whitelists, blacklists and grey lists. With this task, it maintains the QoS Quality of Service on the network. There are various ways for the SBC to achieve this. It allows control of the VoIP signalling and media at an application level. We can set multiple policies on a single SBC. Advanced Routing includes a wide range of routing all of which have a similar end goal that is cost-efficient quality service.

It is important to understand the differences between a carrier-grade Session Border Controller and a firewall. SBC is designed to manage and control real-time voice and video communications sessions. While the conventional security product, the function of the firewall is to block or allow data communications flows. Most business owners, who are not much into the concept wonder if an SBC is similar to a firewall as they are not must sure about their exact requirements. Once, you have set up your company, you need to apply all types of security protocols.

So what type of solution do you need? Is it a Firewall or an SBC? It is possible to divide a computer network into seven layers. From the frame to the network segment, the Firewall works to control up to layer 3 and 4.
