Case Study: One Horizon Group accelerates global VoIP growth with Microsoft Azure

Optimized VoIP startup gains global markets with move to the Microsoft Cloud

One Horizon Group, a telecommunications company from Ireland, faced a significant challenge scaling its optimized VoIP solution due to a sales blocker: a high upfront hardware cost and long setup time required for its on-premises platform. This business model deterred large telecom customers and made expanding into markets like China particularly difficult. To overcome this, the company turned to Microsoft and its Azure cloud platform for a solution.

By migrating its entire operation to the Microsoft Azure cloud, Microsoft provided a scalable and globally distributed infrastructure. This solution eliminated the capital cost barrier for customers, dramatically reduced sales lead times, and enabled easy expansion into new markets. The measurable results for One Horizon Group included a 93% reduction in storage costs, a one-third decrease in licensing costs, and the ability to service over 43 million subscribers, significantly accelerating their global growth.
