Voxbi Cloud PBX is the first mention of the platform here. After that, we refer to it simply as Voxbi. Choosing a PBX or hosted phone system in Luxembourg can feel complex, especially when teams need reliable reachability across offices, remote setups, and hybrid schedules. This guide compares the options on the market and explains why Voxbi has become a default choice for companies that want predictable service wrapped in local expertise.
What is Voxbi?
Voxbi replaces traditional PBX hardware with a EU-hosted platform that keeps the same extension logic your team already knows. Employees handle calls from desk phones, mobiles, or browsers, and the system keeps their professional identity consistent. Core capabilities such as queues, presence-aware routing, analytics, and fixed-mobile convergence are built in. Direct Routing support connects Voxbi with Microsoft Teams, so organisations that standardise on Teams can keep a single interface for collaboration and calling.
Why businesses in Luxembourg choose Voxbi
- Transparent pricing that scales - licences follow a per-user model with optional add-ons, so finance teams can scale telephony at the same pace as headcount.
- Local trust - more than 4,800 organisations in Luxembourg and the Greater Region already run their day-to-day calls on Voxbi, from five-person consultancies to multi-site service desks.
- Advanced features without the admin burden - fixed-mobile convergence, presence-based routing, role-based access, and detailed analytics arrive as standard without forcing teams into heavyweight management tools.
- Integrations that save time - native connectors link Voxbi with Microsoft 365, Teams, Odoo, CTI stacks, ESPA-X, and Salary.lu. The
/featurespage covers the complete catalogue and explains how each component is deployed. - Multilingual, local support - support engineers across Luxembourg and neighbouring countries speak English, French, German, and Luxembourgish, which keeps troubleshooting and onboarding straightforward.
Comparing PBX providers in Luxembourg
The Luxembourg market includes several long-standing suppliers. This neutral snapshot highlights how they position their services:
Voxbi
Cloud PBX designed for hybrid business communication. EU hosting, Microsoft Teams Direct Routing, fixed-mobile convergence, cross-platform softphones, and locally delivered support make it suitable for teams that need flexibility without losing control.
POST · DEEP
POST’s DEEP brand combines connectivity, ICT, and telephony. Its hosted PBX leans on Cisco Webex integrations and bundling with other corporate services.

Frequently asked questions
- What is the difference between PBX and cloud PBX? A PBX is hardware hosted inside your office. A cloud PBX delivers the same call control as a managed service, reachable from anywhere.

- Does Voxbi work with Microsoft Teams? Yes. Direct Routing lets Teams users place and receive external calls using their Voxbi number.
- Where is Voxbi hosted? Infrastructure sits within the European Union, so data governance and redundancy follow EU regulations.
