VoIP Wholesale Business Model: How MSPs Make Money

The VoIP wholesale business model gives MSPs a way to turn business communications into recurring revenue without building their own carrier network. MSPs earn margin on seats, trunks, numbers, usage, services, and new products such as AI Voice Agents. The difficult part is protecting that margin from telecom taxes, billing complexity, support labor, provisioning, and disconnected systems. This guide breaks down the economics behind reselling voice and the operational costs MSPs need to watch. It also explains how Viirtue, ViiBE, and Viirtue’s white-label partner model address those margin pressures.
