Leveraging Open Source Development to Stay Revolutionary

Sangoma Technologies is the primary developer and sponsor of the Asterisk project, the world’s most widely used open source communications software, and the FreePBX project, the world’s most widely used open source PBX software. That makes Sangoma the largest open source telecommunications company in the world.

Sangoma's Open Source Mission

Sangoma has its roots in open source technology. From its founding in 1984, Sangoma has supported various open source projects with its offering of affordable and reliable networking cards and communication products.

Recognizing the importance and value of Asterisk and FreePBX in shaping the modern telecommunications industry, Sangoma sought to preserve the open source vision of these vital projects while ensuring their continued growth and development. Accordingly, Sangoma acquired Schmooze, the Wisconsin-based sponsor of FreePBX, in 2015, and Digium, the birthplace and sponsor of Asterisk, in 2018, in order to gain primary sponsorship of the open source projects.

As proof of Sangoma’s sponsorship in good faith of Asterisk and FreePBX, both open source projects have continued to grow and make major releases, expanding functionality and enhancing application security. Sangoma values the diversity of needs and people we serve. That’s why we offer products and services to facilitate and complement the communications networks of both the open source community as well as those who need a fully-supported, turn-key commercial solution.

Open Source: The Future of Tech and Telecom


Are you looking to engage with the open source community in a friendly, casual environment? If so, we invite you to join us at the monthly Open Source Lounge. It’s an opportunity for our community members, along with our developers, engineers, and support teams, to chat about Open Source and the meaning of life alongside members of the Asterisk & FreePBX community. The Open Source Lounge takes place on the second Thursday of each month at 6 PM CDT. 

We would love to hear your Open Source story. Whether it’s a particular Asterisk or FreePBX implementation, an experience, or a hack you’ve discovered, we encourage you to share it with peers during an Open Source Lounge. If you are interested in a “Show & Tell” spot, simply complete the form below so we can get you scheduled.  

Show & Tell Format –

  • Presentations should be no longer than 20-30 minutes.
  • It’s okay to mention your employer, but please don’t treat this talk like a marketing opportunity.

Industry Disruption: Open Source in Telecom

Sangoma is the primary developer and sponsor of the Asterisk and FreePBX open source projects.


Asterisk is the premier open source framework for building multi-protocol, real-time communications applications. As such, it is not an application itself but a platform that provides a flexible yet reliable basis for developing powerful and secure communications solutions.

The power of Asterisk took the industry by storm, gaining millions of users around the world. In fact, Forbes described Asterisk as “wreaking havoc on the multibillion-dollar phone equipment business.”


FreePBX is a web-based open source GUI (graphical user interface) that controls and manages Asterisk. Initially called the Asterisk Management Portal, FreePBX saves users time by allowing organizations with less technical expertise or resources to use Asterisk.

With over one million production systems worldwide and 20,000 new systems installed monthly, the success and popularity of the FreePBX platform has built a supportive community.

What is Open Source?

The open source method leverages the power of community to develop software. It does this by organizing a project around building a specific tool or program, then making the source code, design documents, and content publicly available under various open source licenses. This allows a community of like-minded developers to work together in building or improving the source code without needing to consult the original publisher or producer for permission. 

Why Open Source Matters

Open source software is more cost-effective, more agile, and more transparent than proprietary development models, and support for releases is typically more robust and lasts much longer. Rather than starting from square one, open technologies afford new and existing developers the opportunity to take advantage of research that has already been done by others in developing new products or contributing improvements to others.

PBXact: Flexible IP PBX Based on FreePBX

The PBXact phone system is Sangoma’s IP PBX designed for advanced deployments where the installation environment requires complex configuration and customization. PBXact is based on FreePBX, making it a very flexible platform without vendor-locking you into proprietary endpoints. The software is tightly controlled by Sangoma, ensuring  the stability and reliability of the software. 

The PBXact GUI is feature-rich, but importantly allows administrators and developers to access  the software in order to integrate third party applications. Commercially supported, PBXact is the solution for administrators and integrators requiring the interoperability of an open source-based PBX.
