📞 Mixvoip: the Luxembourg operator that publishes its prices
Founded in 2008. ILR-licensed. Second-largest fixed voice operator in Luxembourg. Also the operator behind pbx.lu and the parent company of Voxbi. Here is what that actually means for a business choosing a phone system.

🏢 Who Mixvoip is
Mixvoip holds its own operator licence from the ILR (Institut Luxembourgeois de Régulation) and runs its core infrastructure from Luxembourg data centres. This is worth pausing on. Many providers marketed as Cloud PBX in Luxembourg are resellers of international platforms. Mixvoip is the operator itself.
In practice, calls, numbers, and support all live under one Luxembourg-regulated entity, with GDPR applied locally.
📦 What Mixvoip offers
Mixvoip covers four business service areas. Most competitors cover one or two. This matters when you want a single point of accountability for voice, data, and mobile.
🔌 SIP trunks
Certified for 3CX, Innovaphone, and Wildix. Connects an existing PBX to the public network over the internet. See the SIP trunking glossary entry for a plain-language explanation.
☁️ Cloud PBX (Voxbi)
A fully managed hosted phone system. Softphones, mobile app, desk phones. No hardware on premise. See the Voxbi features overview for details.
🌐 Business internet
Dedicated connections, plus a backup path over Eltrona's coaxial network, physically independent from fibre infrastructure.
📱 Mobile services
Business SIM cards on the POST mobile network, mobile device management, and mobile data backup.

👥 Typical client profiles
Based on how Mixvoip positions itself and the kind of clients it wins most often.
🛠 IT resellers and integrators
Deploy 3CX, Innovaphone, or Wildix for their own clients. Need certified SIP trunks with a non-compete clause that protects the end-client relationship.
🏬 SMEs with 5 to 250 employees
Want a fully managed Cloud PBX with multilingual local support and no in-house IT requirement.
🌍 Multi-site businesses across the Greater Region
Offices across Luxembourg, Belgium, Germany, and France. Need one provider covering all four countries.
🔒 Teams with business continuity requirements
Need a backup internet path physically independent from fibre infrastructure. The Eltrona coaxial backup is unique to Mixvoip.
🎯 Where Mixvoip stands apart
Three positioning points that the comparison table above does not fully capture.
💶 Transparent published pricing
Voxbi pricing is public on voxbi.com. SIP trunk pricing is public on mixvoip.com. Most Luxembourg operators use quote-only models, which makes it difficult to compare costs before entering a sales process.
🔁 Coaxial backup path via Eltrona
A secondary internet route over Eltrona's cable network. Because it does not share physical infrastructure with fibre, it survives most fibre-related outages. Unique to Mixvoip among Luxembourg providers.
🔀 Both SIP trunks and Cloud PBX from one operator
Most providers sell one model or the other. A business keeping an existing PBX today can migrate to hosted later without switching operator.
