Today, SBCs are an indispensable part of the SIP-based VoIP networks due to their ability to protect these networks from various types of cyber-attacks as well as add quality to the flow of communication. Talking about the evolution of SBCs, initially, hardware-based SBCs that required complex configuration with the business’s PBX system were the only option to secure the network perimeters. But in today’s cloud-first world, cloud-based SBCs are taking over the market, of course for good reasons.
In this post, we are going to highlight how cloud SBC software reduces infrastructure costs and the complexity of a business.
Easy to Scale
When it was about appliance-based SBCs, a major challenge was choosing the right sized infrastructure for a business network. Opting for a low-end session border controller might appear as a good way to start due to its lesser cost but it carries along the risk of creating bottlenecks when the demand increases. On the other hand, deploying a high-end session border controller could be really expensive for the business and would often result in excess capacity.
However, the cloud approach is more scalable. While there is no on-premise hardware to worry about, cloud SBCs can easily increase /decrease concurrent calls as per the company’s requirements.
Offers Comprehensive Security
IP communications systems are an indispensable and critical part of business communications. DDoS attacks, eavesdropping, and fraudulent toll calls are common types of attacks faced by VoIP networks. Modern-day Cloud SBCs are capable enough to mitigate the risk of extortion, intrusion, and theft of services. Cloud SBC blocks unauthorized traffic and conceals private network topology from malicious entities to secure critical business communications.
- Topology Hiding is a key feature of SBCs wherein the private IP addresses of an application are not exposed to the outside world but are masked. This is done to prevent the mapping of the private network.
- By detecting, deflecting, and limiting the frequency of attempts, SBCs prevent DoS and DDoS attacks on the network which otherwise could bring the company’s operations to a complete halt.
High Availability
Running a VoIP wholesale business demands 99.99% uptime. If we look at the traditional hardware-based SBCs, then achieving high availability would mean the installation of an additional SBC programmed to take over whenever the primary system goes down. This simply means either you have to burn a hole in your pocket or simply run your business with the risk of no backup. But with Cloud Session Border Controller, this problem does not arise. Cloud SBC provides carrier-grade redundancy through standby Virtual Machines which assure a high level of service performance and availability. That’s certainly a more cost-effective solution as compared to that costly redundant hardware.
Reduced Operational Costs
In the past, SBCs were on specialized purpose-built hardware platforms, using proprietary appliances. Today the trend is towards deploying SBCs in the cloud. This software-centric, low up-front cost solution allows businesses to “pay as you grow” with an array of platform choices. The powerful routing capabilities of the Cloud SBC along with SIP interworking lowers service delivery costs through simplified operations.
Smooths Complexity in Connections and Communications
A business handles different types of networks and protocols in real-time through a variety of IP applications. Different types of streaming formats, audio codecs, media, etc., are some of the elements that make up unified communications. SBCs ensure interworking between incompatible protocols, codecs, and SIP variants by acting as a real-time translator. It fully supports each party throughout each session to ensure that there is no loss of features.
Simplifies Session Gatekeeping and Routing
By performing Session Admission Control, SBCs act as network gatekeepers to determine who has the authorization to access the SIP network. With this, bad actors remain at bay from the system as well as the network traffic remains in order.
For fairly large SIP networks, multiple SBCs can be used at multiple network borders. So rather than individually configuring each controller, they can be dynamically managed as a central system using one set of routing and policies. This saves a lot of time and money for the business.
Excellent Customer and Employee Experiences
There are several ways in which SBCs improve the quality of service when used as a part of UCaas i.e. Unified Communications as a Service or CCaaS i.e. Contact Center as a Service. Take a look:
- By analysing traffic and optimising routing, SBCs increase data speeds significantly and also improves the quality of voice calls.
- During higher loads, SBCs can prioritize and redirect sessions so as to maintain performance.
- By detecting and normalising different SIP dialects, SBCs ensure that your agents enjoy seamless and high-quality calls across multiple devices that too in real time.
