Network Connectivity

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.

What are SBCs? We're glad you asked!

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 its networks while managing any interoperability issues.

SIP Trunking

Service providers can use an SBC to protect their network and introduce new revenue streams by providing SIP services to customers using legacy PSTN equipment.


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