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.

Encryption
TLS and SRTP encryption ensures there is no way to “eavesdrop” on calls as they move between the IP phones and IP PBX.
Business Continuity
Maintain essential services while transitioning between phone systems or SIP trunks, or due to catastrophic scenarios.
Interoperability
Ensure compatibility between VoIP carriers and endpoints.
Remote Connectivity
Securely connect remote users to the corporate phone system without requiring a VPN.

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