Voxbone enables telephony applications such as conferencing platforms and call centers to send and receive phone calls, text messages and faxes in 60+ countries making up 93% of global GDP,^[2] with the company’s services accessed through a web platform or REST API.^[3] Voxbone's services are delivered over a private IP network that interconnects with local phone networks in the countries where it operates.^[4]

Voxbone customers include Uber, Zoom, Skype, Dialpad, 8x8, Deutsche Telekom, Telefonica, NTT, Level(3) and Orange.^[5][6][7]

Voxbone was founded in Brussels, Belgium, in 2005 by Rodrigue Ullens and Francois Struman as Voxbone SA/NV.^[8] As a consultant for telecom operators, Ullens noticed the growing demand for phone numbers from other countries and decided to create the business.^[9] The founders’ mission was to offer simplified access to telephony resources through the cloud.^[10]

In 2011, the company launched a “global capacity-sharing model” to tackle the complex tasks and costs associated with planning and managing global voice traffic. Customers are charged according to their peak simultaneous sessions globally (vs. total minute usage per country, or geographical origin of calls, in traditional models).^[11]

In August 2015 Vitruvian Partners LLP (“Vitruvian”), a leading independent European private equity firm, announced that it had acquired a majority stake in Voxbone SA.^[12]

In March 2019 Voxbone announced the launch of its enterprise platform.^[13] Built for business end users, the platform provides voice and messaging in 65 countries.

On October 12, 2020 Voxbone announced its acquisition by Bandwidth for €446 million EUR.^[14] On November 2, 2020, it was announced that the deal had been finalized.^[15]

Voxbone provides two-way voice and messaging services from the cloud for businesses including local, national, mobile and toll-free phone numbers (commonly known as direct inward dialing numbers). Telecommunication providers and/or enterprises use these numbers to extend the reach of their voice networks to international locations, without requiring a local office, network or license for each country.^[16] Voxbone also supports local number portability and offers the ability to port existing local telephone numbers from other local service providers to its network.^[17][18]
