Why Communication Service Providers Need a Session Border Controller

Why Communication Service Providers Need a Session Border Controller

Communication Service Providers today face a lot of complexities as they are trying to make a paradigm shift from the legacy of traditional telecommunication to IP based unified communication infrastructures in all areas of telecommunication. To successfully make this change, the service providers need a well-thought plan to deal with concerns of compatibility, centralized management & security. To some, the mere thought of implementing, managing & securing real-time communications might seem overwhelming.

Today, SIP (session initiation protocol) is at the core of all unified communications including video, voice & collaboration. To make these session flow secure & flawless, Session Border Controllers must be deployed since they are the network cornerstone for new communications & services.

The topmost important reasons for deploying SBCs are:

• Robust Network Security

There are multiple types of VoIP based cyber-attacks that can be carried over a provider’s network, which significantly impacts productivity & revenue. Some common VoIP attacks include service theft & fraud, DoS/DDoS attacks, spoofing, registration storms, etc. SBC protects real-time communication network from these attacks via different ways & ensures security & flow of SIP sessions between internal & external network.

• Dynamic Scalability

The SIP communications traffic will continue to grow as your business grows with more users & traffic load. So, to gain carrier-grade assured performance & maximum service availability under heavy traffic load & quality of service policies, deploying an SBC gains paramount importance.

• Real-Time Performance Monitoring

With the carrier-grade network, one needs a way to facilitate high-quality data collection & organization that is timely, relevant & accurate in order to better manage ongoing programmatic activities. A Session Border Controller does exactly that & much more. It provides real-time comprehensive performance reports on live calls.

• Intelligent Alert System

A robust intelligent alert system provides additional security to the service provider’s network. It provides different types of alerts for the unusual system, performance, customer behavior & recharge. A feature like this in an SBC saves communication service providers an immense amount of money. Based on the triggering factors, they can decide on actions beforehand to be taken by the SBC in those situations; saving resources, frauds & in turn increase their profits.

• Extensive SIP Interoperability

One of the major functions of SBC is to provide seamless sessions between different VoIP solutions. Different vendors & VoIP networks may communicate in incompatible protocols & codecs. This will result in a loss of traffic. So, deploying an SBC provides a smooth experience in terms of interworking & interconnecting different networks and the protocols running over them with the help of SIP normalization.

• Transcoding & Interworking

One of the major jobs of Session Border Controller is to transcode calls & media services. SBC allows communication providers to offer more services with lower investment but with higher ROI (return on investment). The interworking function enables the connection of networks between different IPs, making it possible for voice & video calls coming from different switches to work seamlessly. Thereby, allowing the communication services providers to provide flawless services.

The reasons mentioned above make a session border controller an extreme necessity for communication service providers, in today’s time. If you think, you need an SBC for your business, take a free demo of REVE SBC. First, try and then decide.
