What is session border controller

Increasingly however, providers are moving towards the virtual SBC model, where they can handle it from their cloud environment. As many companies are choosing the option of having less hardware to manage on premises, SBCaaS is a good fit for companies using more cloud-based services. It means that IT teams can utilize the benefits of virtualizing servers, storage and other infrastructure. Those benefits include faster deployment, higher utilization rates, ease of management and scalability, resulting in lower overall operating costs.

SBCs are mission-critical for enterprises and service providers. As such, you need to work with a vendor who has the experience and expertise to deliver a resilient, high availability solution with a low to zero failure rate.

The modern unified communications UC ecosystem is often comprised of complex, multi-vendor systems, and its efficient operation relies on the compatibility and communication between all the moving parts - including session border controllers. Get the support you need to effectively monitor, troubleshoot and optimize SBCs, and deliver seamless, reliable and high-quality customer and remote working interactions.

Session border controller trends Summary. Related Articles. A guide to disaster recovery and business.. The only certain thing in the business world is that nothing is for certain. 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. SBCs can handle the task of monitoring communication traffic and applying policies in real-time much better than conventional networking devices like routers, firewalls, and traffic shapers. SIP is an open signaling protocol that the SBC uses to establish, maintain, and terminate communication sessions between two endpoints.

The SBC will then route the session data to the public network. Most SBCs enable interoperability across different vendors by normalizing signaling stream headers and messages.

More specifically, SBCs convert data between multiple dialects of SIP to ensure different systems can communicate with each other. SBCs are also capable of creating connections that translate between multiple voice or video codecs like H. In some cases, SBCs may also transcode signals into higher or lower quality bandwidths to match the current network capabilities.

This ensures that communication sessions happen seamlessly, despite having connections taking place over complex and multi-vendor telephony infrastructures. Once the necessary session data reaches the public network, carriers route calls across the PSTN network to their destination.

With Microsoft Calling Plans, Microsoft is the carrier and requires individual plans for each country. When using MS Teams Direct Routing, however, most third-party providers have a global network of carriers available.

When using Calling Plans, this is taken care of by Microsoft as part of their services. SBCs are a critical aspect of cloud telephony infrastructure. Their granular control over communication sessions offers enormous benefits to organizations in terms of quality of service, security, and reliability.
