VoIP is gaining popularity among industry leaders and serial entrepreneurs. There are so many organizations which have started adopting the VoIP tools and network. Even many people have started offering the VoIP services. And the best thing is there are a few countries which are encouraging telecom service providers to adopt the VoIP technology to offer telecommunication services. These big telecommunication networks, which are made up around SIP may face some concerned issues. Thus, the SBC solution is one of the must have tools of this arsenal to ensure the whole network is secure and reliable. In the past, the SBC solution came with only a few basic features, but with the invention of technology, the SBC solution comes with many features. Even there are different types of SBC solutions available in the market. One may also get custom SBC software development service based on their requirements. When you go for the custom development of an SBC solution, you may select the number of features you want. In this article, we will explore two main and basic characteristics aka functionalities of the Session Border Controller (SBC) ...
... Solution, which are must have features of any SBC solution.

Two core features of an SBC Solution are listed below:
Security
interoperability

Let's check both in detail.

Security
When you use VoIP network, you have to deal with the SIP packets. The conventional firewall setup doesn't allow SIP packets to traverse through it. Thus, to allow this SIP traffic, you have to create holes in your firewall setup. This creates holes in the security system on your network as well. The reason is now, another notorious or malicious traffic may also enter into your network. Here, the Session Border Controller can be a great security mechanism. The SBC solution is much more powerful than a normal firewall. It sits on the border of the network and check each incoming and outgoing packet, data and other media at the session level itself. If the traffic seems secure then only it will allow it to enter or leave this secure VoIP environment. It can also hide the topology of the network so the external environment will never get to know your network setup, which makes it more secure. The SBC solution can protect the VoIP network from any type of security threats, including toll frauds, DoS (Denial of Service) and DDoS (Destructive Denial of Service) attacks, and many more.

Interoperability
This is another core feature of a Session Border Controller Solution. In fact, this is also much needed feature, specifically when you are offering the VoIP services or dealing with different networks for exchange of information. To be specific, it is a pretty normal scenario that different VoIP networks are using different types of setup. They can have different network topologies or they might be using different audio, video or other codecs. Here, the SBC solution is very useful. It works as a translator between two different networks and can make the operations fluid even between two completely different VoIP environments. It can perform transcoding on its own which, make sure to avoid usage of additional tools for interoperability function.
