What Symbio does

Symbio is an Asia-Pacific-focused cloud communications platform provider that delivers wholesale voice, SIP trunking, numbering, messaging, and white-label connectivity services to two distinct customer segments: enterprise and government organisations, and service providers, telecom resellers, CPaaS/UCaaS/CCaaS platforms. The company operates a fully interconnected, geo-redundant voice network across Australia, New Zealand, Singapore, and Malaysia, with planned expansion into Taiwan and a stated 2030 vision to support 100 million numbers on its network. Founded in 2002 as Symbio Networks (formerly part of MNF Group, now consolidated under Symbio Holdings Limited and owned by Aussie Broadband Group, ASX: ABB), Symbio has grown through both organic market entry (notably Singapore, where it became the first fully interconnected carrier to build a local voice network in over 20 years) and acquisitions, including TNZI (Telecom New Zealand International, 2015) and the Intrado UCaaS business in Australia (2023).
