Fusion Connect

Fusion Connect is an Atlanta, Georgia-based managed communications provider that has built its UCaaS offering on top of Microsoft Teams Direct Routing, positioning the company as a single-vendor solution for organizations that want Microsoft Teams as their primary communications platform without managing the PSTN connectivity layer independently.

Platform Architecture

Fusion Connect's UCaaS service leverages Microsoft Teams Direct Routing, enabling organizations to make and receive PSTN calls through the familiar Teams interface while Fusion Connect manages the SIP trunking, number porting, and carrier-grade voice network behind it. This architecture is particularly compelling for organizations already operating in the Microsoft 365 ecosystem — it eliminates the need to introduce a separate UCaaS application alongside Teams.

Network Infrastructure

Unlike pure software UCaaS providers, Fusion Connect operates its own nationwide network infrastructure — the same fiber and MPLS footprint that serves its connectivity customers. This ownership model delivers a 99.999% uptime SLA backed by genuine network-level control rather than reliance on third-party carrier agreements. For organizations that procure both connectivity and UCaaS from Fusion Connect, a single managed services agreement governs both layers, reducing vendor complexity and support escalation friction.

Vertical Strengths

Fusion Connect has built particular depth in healthcare, legal, financial services, and state/local government — sectors where CPNI compliance, HIPAA-eligible configurations, and carrier-grade call quality are non-negotiable requirements. The company's managed services model means clients receive dedicated support rather than self-service portals, which aligns with the expectations of IT teams in regulated industries.

Contact Center and Collaboration

Microsoft Teams-native contact center integrations and collaboration capabilities are available through Fusion Connect's managed platform, enabling organizations to consolidate their entire communications stack — employee voice, team messaging, video, and customer-facing call queues — under one vendor relationship with a single support escalation path.
