SIP (Session Initiation Protocol) is in existence for more than two decades now. Still the confusion among the people about what SIP actually does is there. The same thing applies to SBC aka Session Border Controller. Almost all know that Session Border Controller works on sessions and it is part of the SIP solution, but still there are many people who are not much clear about its role, power and benefits. Even the professionals working in the Telecom industry might lack the important information about the Session Border Controller. For example, many Telecom executives don’t know exactly where does SBC sit on? Does it sit on the edge of the network or inside the DMZ? This lack of knowledge resists people adopting this powerful solution or investing on it. This article will share some great insights and top 5 reasons of why you should get a Session Border Controller (SBC) solution for your enterprise.
We all use network and it is pretty clear that our network service provider uses a certain kind of security mechanisms to keep our network secure. However, they are trying to keep the overall network secure and not us particularly. So why not to use dual security mechanism to make sure we are double secured with a Session Border Controller solution, which is taking care of all known and unknown security threats which may compromise our security. It is similar to an analogy that we do live in the gated society still we lock our doors.
The Session Border Controller solution checks each call getting in and going out of the network. It checks the required bandwidth for an audio call and a video call which can be only known by you for your network. The Session Border Controller (SBC) solution gets configured to identify the excessive bandwidth usage for a call, which can be a hack attack. It works as a call admission control on ingress and egress points to avoid any type of hack attacks.
Transcoding and Translation
It is a common scenario when you are dealing with two different types of communication elements. If we talk technically then you might come across a situation where you need to translate SIP to H.323; or you might need codec transcoding from G711 to G729; or RTP to SRTP; or TLS to unencrypted SIP; or IPV4 to IPV6. The carrier will not perform this transcoding and translation, which demands the Session Border Controller solution at customer premises.
In a SIP environment, whenever call recording takes place, the software taps into the trunk and split the media into two different paths. In TDM, same task need hardware. However, in SIP environment this can be easily done with the Session Border Controller solutions to record calls and that also without compromising its quality.
WebRTC Integration in the Existing System
WebRTC is newly launched technology. Due to its feature of real time and remote communication support, it is getting popular, specifically among the call centers. However, these call centers might already have the expensive call center software. Here, the vendors add WebRTC gateway functionality into their existing call center product using an SBC. This allows offering WebRTC enabled call center solution with a single edge device.
So these are the top 5 reasons to have a Session Border Controller solution which you might not be aware of! We offer a Session Border Controller solution with custom features. For more details, contact us!
