AudioCodes Mediant SBC

A Session Border Controller (SBC) is a device or software that sits between your company phone system and the outside network, such as a SIP trunk provider or Microsoft Teams. It protects calls from attacks and toll fraud, fixes SIP differences so systems work together, routes each call to the right place and keeps call quality steady. SURIA supplies, configures and supports AudioCodes Mediant SBCs in Indonesia.

An SBC (Session Border Controller) is built to handle voice calls at the edge of your network. A normal firewall filters traffic but is not built to manage phone calls. An SBC understands SIP calls, can fix differences between phone systems, hides your internal network, and keeps call quality stable. Many companies use both.

It is strongly recommended, and required for Microsoft Teams Direct Routing. Some IP PBXs can connect to a SIP trunk directly, especially over a private link from the provider. An SBC adds protection from attacks and toll fraud on the public internet, fixes differences between your PBX and the provider's SIP settings, and gives you one controlled point for all calls in and out. SURIA can check whether your setup needs one.

Yes. Microsoft lists AudioCodes Mediant SBCs from the Mediant 500 to the Mediant 9000, plus the Virtual and Cloud Editions, as certified for Teams Direct Routing. This certification ensures seamless interoperability with the Teams voice platform, including support for Local Media Optimization, which keeps call audio on the local network for users in the office to improve call quality.

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.
