Session Border Controller (SBC) Hosting


Sangoma’s Session Border Controller’s (SBC) are advanced and flexible Session Border Controllers that allow you to interconnect different SIP networks securely to perform SIP trunking and general SIP call routing with its advanced XML-based routing engine. Our software creates rock-solid virtual environments, enabling the underlying hardware to enjoy better resource utilization, enhanced security, and unrivaled performance.

If you wish to maintain a secure and efficient network, that handles the different types of signals produced by different components with ease, it’s time to shop for the right Session Border Controller for your application.

Just as the firewall protects the data network, a Session Border Controller (SBC) is required to protect both the data and voice network when VoIP is integrated into the system.

All of Sangoma’s SBCs provide the same carrier-grade functionality, including prevention of toll fraud, denial of service attacks and eavesdropping. They enable VoIP traffic to navigate firewalls and ensure interoperability between different SIP implementations.

Frequently Asked Questions

Have Questions? No Worries. We are here to help.
Can one SBC VPS protect multiple PBX Servers? If so do I just need to purchase the additional call paths to handle the volume of calls for those PBX’s (up to 30 call paths)?

One Hosted SBC VPS server can protect any number of Carriers and FreePBXs (VPS’s). Only the number of “Max Call Licenses” are needed to be purchased to handle the call volume for all of the FreePBX servers. In the near future we will be releasing larger plans to handle high call volume.

Do I need to purchase a Hosted SBC VM for every FreePBX VPS?

No, One SBC can route calls to and from any number of FreePBX Servers.

What is a call path defined as? Is it calls coming in and out via SIP trunks? Or is it all connections including a SIP Phone (extension)?

One Call License = 1 Trunk Provider to SBC Session + 1 SBC to PBX Session


One Call License = 1 Remote Phone to SBC Session + 1 SBC to PBX Session

Another Example;
Two Call Licenses = 1 Remote Phone to SBC Session + 1 SBC to PBX Session + 1 PBX to SBC Session + 1 SBC to Trunk Provider Session
