From telecom operator to cloud PBX.

Mixvoip started in 2008 in Luxembourg and grew into one of the country's largest fixed-line operators, serving businesses across Luxembourg, Belgium, France, and Germany. Along the way it earned the trust of 30% of Luxembourg's municipalities and 45% of its care homes, the kind of customers who cannot afford a phone system that fails.

Voxbi exists because businesses also need their phones to work with the tools they already run. Microsoft Teams, Odoo, calendars, CRMs. So Mixvoip built Voxbi: phone software that lives in a browser tab, connects natively to those tools, and scales from 5 users to 5,000 on the same platform. Voxbi is the tech company; Mixvoip stays the operator underneath, carrying the numbers, the carrier network, and the regulatory duties.

We build in the open and stay close to our customers. Mixvoip is a Gold sponsor of the Odoo Community Association, keeps Microsoft-certified engineers on staff, holds a 4.64 out of 5 customer satisfaction rating, and plants a tree for every piece of feedback received.

Built in Europe

European by design.

Calls, recordings, and metadata stay in European data centers. GDPR and EU AI Act compliance are built into the platform itself, and every call and configuration is protected with encryption over HTTPS, SIP TLS, and WebRTC. Even the AI stays on European soil: call transcription, summaries, and sentiment analysis are processed on MeluxINA, Luxembourg's national supercomputer.
