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.

Session Border Controller Features

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.
Ensure compatibility between VoIP carriers and endpoints.
Remote Connectivity
Securely connect remote users to the corporate phone system without requiring a VPN.
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 optimised codecs.
Hardware Redundancy
Ensure business continuity during catastrophic hardware failures by mirroring two SBCs together.
