OVERVIEW

What is a Session Border Controller (SBC)?

In simple terms, a Session Border Controller (SBC) is like a traffic cop for internet-based communication (voice and video calls). It helps manage and organize the flow of data between different devices or networks, ensuring that the communication is secure and runs smoothly. The SBC handles tasks like keeping communication connections safe from threats and controlling the quality of the communication experience.

SBC Features

A Session Border Controller (SBC) offers several features to improve the performance, security, and compatibility of Voice over IP (VoIP) and Unified Communications (UC) networks:

Border Control

SBCs manage traffic between different networks, such as a private IP network and the public internet, to prevent unauthorized access and ensure the security of communication sessions.

Protocol Normalization

SBCs can translate between different communication protocols, allowing devices with different communication standards to communicate with each other.

Improved Call Quality

SBCs can prioritize and manage network traffic to ensure high-quality communication sessions, even in congested network environments.

Load Balancing

SBCs can distribute network traffic evenly across multiple servers or network paths, ensuring optimal performance and reliability.

Interoperability

SBCs can enable communication between different devices and systems, such as VoIP phones, video conferencing systems, and mobile devices.

Monitor & Reporting

SBCs can provide detailed logs and analytics about network traffic and communication sessions, allowing administrators to monitor network performance and troubleshoot issues.

Benefits of SBCs

SBCs provide a comprehensive solution for VoIP and UC networks, offering protection, compatibility, enhanced voice quality, scalability, and cost savings.

SBCs & Microsoft Teams

The Session Border Controller (SBC) acts as a key middleman in a Microsoft Teams Direct Routing setup, enabling voice and video communications between Microsoft Teams and the public telephone network. This enables seamless and secure connectivity, allowing users to make and receive calls, take part in video conferences, and share screens with others both within and outside their organization.

BENEFITS

Protecting your network

SBCs act as a security guard for your VoIP and UC networks, defending against cyber threats like Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks while preventing unauthorized access.

Connecting different systems

SBCs ensure seamless communication between various VoIP and UC systems, allowing them to work together effortlessly, regardless of the underlying protocols, codecs, or signaling technologies.

Enhancing voice quality

SBCs optimize network performance, prioritizing voice traffic, controlling jitter, and minimizing latency, ultimately leading to improved voice quality and fewer call failures.

Scaling up your network

SBCs support large-scale deployments, managing network resources efficiently and handling high traffic loads, ensuring smooth operation and uninterrupted service as your network grows.

Reducing operational costs

SBCs help lower expenses by managing network resources, optimizing bandwidth usage, and minimizing network maintenance costs, resulting in overall cost savings.
