A Session Border Controller (SBC) is a vital element in modern VoIP and SIP-based communication networks. It acts as a gatekeeper between different networks, securing the flow of voice, video, and messaging traffic while ensuring seamless interoperability across platforms. Whether you’re an enterprise using SIP trunks or a telecom provider managing large-scale communications, an SBC helps safeguard your network from threats like toll fraud and DDoS attacks, maintains call quality through traffic control and media optimization, and ensures compliance with telecom regulations. With features like NAT traversal, encryption, and protocol normalization, SBCs are the backbone of secure, high-performance real-time communication systems.

Sheerbit provides full-cycle deployment and configuration of Session Border Controllers for on-premise, cloud, or hybrid environments. Our team ensures high availability, media anchoring, and optimized call routing for carrier-grade reliability.
We help businesses integrate SBCs with their SIP trunks to ensure secure and interoperable communication between internal VoIP infrastructure and external SIP carriers, with support for NAT traversal, media handling, and protocol normalization.
Our SBCs act as a security firewall, offering deep packet inspection, DoS/DDoS protection, signaling encryption (TLS/SRTP), topology hiding, and fraud detection, ensuring your voice traffic stays secure and compliant.
Sheerbit delivers customized multi-tenant SBC solutions for VoIP service providers, enabling isolated, secure communication channels for each tenant while maintaining centralized management and scalability.
We configure SBCs to implement intelligent call admission control (CAC), bandwidth policing, and Quality of Service (QoS) prioritization to maintain high call quality, even under heavy network load.
Sheerbit SBC solutions enable seamless communication between different SIP variants, codecs, and network topologies by performing SIP normalization, header manipulation, and codec transcoding.
For businesses seeking scalable and cost-effective solutions, we offer SBC-as-a-Service hosted in secure data centers or cloud platforms, managed and monitored by our expert team.
We integrate real-time monitoring, CDR logging, and advanced analytics with your SBC environment. You gain actionable insights into call flow, performance, and security events.
Sheerbit offers 24/7 SBC support with proactive maintenance, firmware updates, and SLA-based services to ensure your SBC infrastructure stays updated, secure, and optimized.
Session Border Controllers serve as a critical security layer between internal VoIP systems and the outside world. They protect voice networks from threats such as denial-of-service attacks, toll fraud, SIP spoofing, and unauthorized access.
One of the key strengths of SBC solutions is their ability to support protocol and codec interoperability. They allow seamless communication between systems that use different VoIP standards by handling SIP-to-SIP normalization, codec transcoding, and even translating between SIP and H.323 protocols
SBCs play a vital role in maintaining consistent voice and video call quality. They actively manage media traffic to prevent jitter, echo, latency, and packet loss. Through bandwidth allocation, traffic prioritization, and real-time performance monitoring, they ensure high-quality communication across varying network conditions.
In modern distributed environments, many VoIP endpoints are located behind firewalls and NAT devices. SBCs are designed to overcome these barriers by enabling NAT traversal. This allows remote users, mobile SIP apps, and home office setups to establish secure and reliable voice sessions without manual network reconfiguration.
Many industries require strict compliance with communication regulations. SBCs often come with built-in features such as session logging, call detail record (CDR) generation, and lawful interception support.
SBCs provide intelligent call routing mechanisms that improve overall network efficiency. They handle tasks such as least-cost routing, failover management, and load balancing across multiple SIP trunks or media servers.
Sheerbit brings years of hands-on experience in VoIP architecture and SIP protocol optimization, ensuring that your SBC deployment is both secure and high-performing.
Whether you need SIP normalization, NAT traversal, or traffic routing, Sheerbit crafts SBC solutions specifically aligned to your telecom infrastructure and compliance needs.
