Sangoma

Sangoma Technologies is a publicly traded communications technology company (TSX: STC) headquartered in Markham, Ontario, Canada. Through a series of strategic acquisitions — most notably Digium (the creator of Asterisk and FreePBX) and Star2Star Communications — Sangoma has assembled one of the most comprehensive portfolios in the SMB-to-mid-market UCaaS space.

Open-Source Heritage

Sangoma's acquisition of Digium brought ownership of Asterisk — the world's most widely deployed open-source telephony engine — and FreePBX, the GUI that has made Asterisk accessible to hundreds of thousands of deployments globally. This heritage gives Sangoma an unmatched position with IT teams and MSPs that have built their telephony expertise on the open-source ecosystem, and enables a level of platform customization that proprietary cloud UCaaS providers cannot match.

Cloud PBX via Star2Star

The Star2Star acquisition added a mature, enterprise-tested cloud PBX platform to Sangoma's portfolio — the foundation of the company's PBXact Cloud and Switchvox Cloud UCaaS offerings. These platforms deliver carrier-grade hosted communications with a 99.999% uptime SLA for organizations that want cloud economics without fully abandoning the configurability of an Asterisk-based architecture.

Hybrid Deployment Flexibility

Unlike most UCaaS providers that mandate cloud-only deployments, Sangoma supports on-premises, cloud, and hybrid architectures — a meaningful capability for organizations with edge computing requirements, data residency restrictions, or existing hardware investments they want to extend rather than replace.

Acquisitions Depth

Beyond Digium and Star2Star, Sangoma's acquisition of NetFortris (managed security services) and VanillaSoft (sales engagement CRM) reflects an ambition to extend beyond pure UCaaS into adjacent technology categories — particularly relevant for sales organizations and security-conscious mid-market companies.
