Sangoma Session Border Controllers

The Right Way to Protect your VoIP Environment

A Session Border Controller (SBC) will allow you to connect your remote workers and SIP trunk(s) securely to your phone system without compromising security, automatically detecting VoIP threats and taking action. 

Additionally, Sangoma SBCs  can automatically translate codecs and audio with built-in interoperability and transcoding capabilities.

When Would You Use a Session Border Controller?

Remote Workers

Connect remote workers to the corporate phone system without opening up ports in the firewall. The SBC monitors all the traffic for any malicious registrations or threats and takes immediate action.

Cloud Phone Systems

In a hosted environment, enterprises rely on the service provider for all their phone system services. An SBC protects their networks while managing any interoperability issues.

SIP Trunking

Service providers can use an SBC to not only protect their network but also introduce new revenue streams by providing SIP services to customers using legacy PSTN equipment.

Security

SBCs provide protection against malicious attacks such as Denial-of-Service, toll fraud, and SIP/RTP flooding, while hiding network topology to keep network routes unexposed.

Session Border Controller Features

VoIP Protection

Protects VoIP networks from malicious attacks.

Call Routing

Provide low-cost routing and load balancing across trunks.

Call Limiting

Limit the amount of traffic through call paths to ensure quality of service and mitigate risk of toll fraud.

Simplified Licensing

All SBCs are field upgradable and licensing is per session-based, meaning all the features are always included.

Media Transcoding

Generate the best quality of service the connection can provide, from HD voice quality to small bandwidth optimized codecs.

Flexible Routing

Advanced flexible call routing with automatic failover and bypass routing.

Advanced Troubleshooting

Built-in call tracing and debugging utilities.

Hardware Redundancy

Ensure business continuity during catastrophic hardware failures by mirroring two SBCs together.
