What is a Session Border Controller (SBC)?
A Session Border Controller, sometimes called an SBC, is a dedicated device that controls and safeguards IP communication flows. As their name suggests, Session Border Controllers are installed at network boundaries to manage IP communications sessions. SBCs were first designed to protect and manage VoIP networks. Still, they handle all real-time communication channels, including VoIP, SBC voice, IP video, text chat, and collaboration sessions.
Enterprise Session Border Controllers are dedicated hardware devices or software applications that govern session initiation, conduction, and termination in Voice over IP (VoIP) networks. Essentially, they act as the intermediaries between the internal and external networks, ensuring the smooth flow of SBC voice and video communications. SBCs also play a crucial role in enhancing network security, routing, and policy adherence.

The demand for SBCs will increase as businesses adopt more sophisticated UC networks due to call routing, security, interoperability, and network administration demands.
2. Knowledgeable Management
Enterprise Session Border Controller can guarantee that every organization has the best path to deliver a call to its destination, in addition to increasing the security of VoIP network interactions. Therefore, in the era of the customer experience, the call routing procedure is becoming more and more crucial. Intelligent call routing ensures the appropriate dialogue gets to the proper person to increase satisfaction and reduce business costs. Even better administration of SIP connections through multiple devices is made possible by the intelligent control that the Session Border Controller renders. As a result, businesses have greater flexibility in using the solutions required for an improved communication strategy.
3. Calls for BYOD
With businesses implementing BYOD policies, SIP communications traffic will keep growing as the workplace becomes more adaptable and mobile. Due to the BYOD movement, organizations must manage more SIP devices for end-to-end security. An ideal Session Border Controller solution will be able to handle the increasing traffic demands of evolving enterprises and give them the resources they require to accommodate a shifting workforce. SBC solution providers are increasingly investing in SBC solutions that offer security and the scalability that businesses need as they examine various facets of their digital transformation roadmap.
4. The need for BYOC
Over the past two years, organizations have been pushed to adopt cloud-based collaboration systems like Microsoft Teams and Zoom due to the rise in remote and hybrid working. They are now attempting to connect these new platforms with outdated telephony systems as they return to their workplaces. Enterprise Session Border Controller can help enterprises keep their current phone systems and phone numbers while utilizing the power of the cloud by routing legacy phone traffic to platforms like Teams and Zoom. The ownership of the SBC will pass from the end user or a service partner to the carrier itself, thanks to programs like Operator Connect.

Functions of a Session Border Controller
SBCs control media streams and IP communications signaling to perform several tasks, such as:
-
Security
SBCs provide media and signaling encryption to assure confidentiality, guard against impersonation/masquerade, safeguard against toll fraud and service theft and provide Denial of Service (DoS) and Distributed DoS (DDoS) assault protection.
-
Interoperability
To reduce multi-vendor incompatibilities, SBCs standardize the headers and messages of the SIP (Session Initiation Protocol) signaling stream.
-
Interworking
SBCs allow for the interoperability of several protocols (such as SIP-to-H.323) or codecs (such as g.711 to g.729 transcoding).
-
QoS Assurance
SBCs implement call admission control (CAC) rules, type of service (ToS) tagging, and rate limitation to ensure service quality.
-
Session Routing
SBCs route sessions across network interfaces, allowing least-cost routing (LCR) or high availability.

How Do Session Border Controllers Work?
Overseeing the signals and frequent media streams involved in initiating, conducting, and ending phone calls or other interactive media encounters is the primary responsibility of the SBC Session Border Controller. In addition to providing improved security features, including call admission control, toll fraud detection, and denial-of-service (DoS) protection, they can translate the protocol. SBCs use sophisticated regulations and guidelines to ensure that only authorized sessions are conducted.
SBC Voice also safeguards VoIP networks’ Session Initiation Protocol (SIP). SIP is one of the most crucial installation components for conventional service providers. It is a fundamental standard that controls how gadgets talk to each other virtually.
