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 has its roots in open source technology, supporting various open source projects since 1984 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.

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

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.”
