AudioCodes Mediant SBC

A Session Border Controller (SBC) is a network device that sits at the boundary between your enterprise phone system and the public SIP network, protecting voice traffic from security threats, ensuring compatibility between different SIP implementations, and maintaining call quality. An SBC is essential for any organization connecting a PBX to SIP trunks or enabling Microsoft Teams Direct Routing.

Yes. The full AudioCodes Mediant portfolio is Microsoft Teams Direct Routing certified. This certification ensures seamless interoperability with the Teams voice platform, including support for Local Media Optimization to improve call quality for internal Teams calls.

AudioCodes Mediant SBCs are available as physical hardware appliances, virtual editions running on VMware, KVM, or Hyper-V, and cloud native editions hosted on AWS, Azure, GCP, or Kubernetes. This range allows organizations to choose the deployment model that best matches their infrastructure and scaling requirements.

AudioCodes Mediant SBCs include SIP header manipulation, protocol normalization, and media transcoding capabilities that allow them to bridge incompatible SIP implementations between legacy PBX systems and modern IP networks. Organizations can migrate incrementally from TDM or older SIP systems to Microsoft Teams or a modern cloud platform without replacing all endpoints at once.

AudioCodes Mediant SBCs include TLS and SRTP encryption for all voice traffic, DoS and DDoS protection against SIP-based attacks, topology hiding to conceal internal network structure, and intrusion detection and prevention capabilities. These features protect enterprise voice infrastructure from the most common VoIP security threats.
