BI Voxbi

BI Voxbi

Voxbi is the cloud PBX software brand of Mixvoip, a Luxembourg telecom operator registered since April 2008. Voxbi is the software and admin layer; Mixvoip carries the numbers, network, and regulatory status. Best fit: LU and Greater Region SMEs that want EU-hosted calling with published prices. Worst fit: buyers needing 24/7 phone support on a low-cost plan.

A. House card

Three genuine strengths

1. Complete public price list for both lines, plus a downloadable per-destination call rate table covering 667 destinations. Source: voxbi.com/pricing and voxbi.com/pricing/call-rates, 11 Aug 2026.
2. Regulated operator status in depth, not just an EU sales office: ILR (LU), IBPT 4065 (BE), Bundesnetzagentur 18/010 (DE), ARCEP MXVP (FR), ACM/25/196334 (NL), plus ten more. Source: mixvoip.com/legal/impressum/, 11 Aug 2026.
3. ISO 27001 certificates published as downloadable PDFs for the Luxembourg, Belgian, and German entities. Source: mixvoip.com/company/accreditations/, 11 Aug 2026.

Three honest limitations

1. No phone support and no SLA with downtime credit on any Voxbi One plan, including the €3.10 tier. Source: voxbi.com/pricing comparison table, 11 Aug 2026.
2. The published partner directory lists four partners, all in Luxembourg and Belgium, while the homepage claims integrators "across Europe". No Germany, France, or Netherlands partner is named. Source: voxbi.com/partners/find, 11 Aug 2026.
3. AI transcription is capped at 15 analysed calls per month on Free, Starter, Plus, and Channel. Only Plus AI is uncapped, and the AI feature page does not mention the cap. Source: voxbi.com/pricing table versus voxbi.com/features/ai, 11 Aug 2026.

Three approved one-liners

• "Two lines: run it yourself from €0, or have us run it with an SLA from €5.20 per user."
• "Numbers, network, and regulatory filings sit with a notified operator, not a reseller."
• "Every price is on the website, including a 667-destination call rate table you can download as CSV."

Three things never to say

Disqualifiers

A2. Claims register

B. Fit qualification questions

Cost and billing model

1. How many people need their own extension, and how many calls do you actually run at the same time? Fewer concurrent calls than users points to Voxbi Channel at €14.50 per channel rather than per-user pricing.
2. Do you already own phone numbers, or do you need new ones? Paid Voxbi One plans include zero numbers, at €1.60 each.
3. Which countries do you call most? Starter and above reach Zone International; the Free plan is limited to Zone EU plus the United States and Canada.
4. Is a predictable flat monthly bill more important than the lowest headline price? Voxbi Managed publishes flat unlimited user rates alongside metered ones.

Feature and gating

1. Do you need call analytics dashboards? Those start at Plus on Voxbi One and at Business on Managed.
2. How many calls per month need an AI transcript? Above 15, only Plus AI or Managed Enterprise fits.
3. Do you need Microsoft Teams calling? That requires Plus or above plus €50 per month flat, plus a Microsoft Teams Phone licence you buy from Microsoft.
4. Do you need to keep your existing SIP carrier? BYOC starts at Plus.
5. How long must call recordings be retained? Voxbi One does not publish a retention figure; Managed publishes 3, 14, 60, or 120 days by tier.

Operational and support

1. Does anyone on your team need to reach a human by phone when calls stop working? No Voxbi One plan includes phone support.
2. Do you want a written uptime guarantee with financial credits? That exists only on Managed, and only above the Basic SLA level.
3. Who will build and maintain your call flows? Self-service means your team; Managed means ours.
4. Do you need on-site intervention? On-site is limited to Luxembourg, Belgium, and select regions of Germany and France.

Strategic and compliance

1. Does your auditor need to know exactly where call recordings sit? Voxbi publishes "EU data centres" but does not name the country or facility.
2. Do you need Luxembourgish-language call transcription? Support is limited across all vendors, ours included.

Ten FAQ entries

Five commercial BOFU pages

pbx.lu maintenance list, strictly factual

1. "A fully managed Cloud PBX service" and the section "Fully managed, not self-service" are both wrong. Voxbi One is a self-service line with a free tier.
2. "The product targets businesses from 5 users upward" and "Voxbi is available from 5 users upward" are wrong. The Free plan serves up to 3 users.
3. "Look elsewhere if you have 1 to 3 users and need the simplest possible setup" is wrong. That is exactly the Free plan's target.
4. "Look elsewhere if you are deeply embedded in Microsoft 365 and want Teams-native calling" is wrong. Voxbi provides managed Direct Routing.
5. "Microsoft Teams integration" is listed among included integrations. It is a €50 per month add-on requiring Plus or above.
6. "Greater Region numbers: LU, BE, DE, FR" needs checking against the published self-service catalogue, which names DE, FR, NL, ES, IT, PT.
7. "Running its own core network from Luxembourg data centres" is stronger than voxbi.com supports. The site says EU data centres without naming a country.
8. "Support languages: 4" carries no source. The site publishes EN, FR, DE, NL, which is a website-language fact, not a support-language fact.
9. "Desktop softphone for PC and Mac" is now confirmed as native apps on both, and should also mention the browser client and the absence of a Linux app.
10. The coaxial backup path over Eltrona's cable network was not verified in this pass and should be re-sourced or removed.
11. "Updated April 2026" needs refreshing, and the read-time line should be rechecked after edits.
12. "Subscription, hardware, and numbers are listed separately" is half right. Hardware is not priced on voxbi.com.

12. Retention and switching

13. Evidence gaps and unknowns

• The EU country and data centre that host calls, recordings, transcripts, and metadata
• ISO 27001 certificate numbers, certification body, scope statements, and expiry dates
• Whether the MeluXina claim on the About page is confirmed by LuxProvide
• Call recording retention on Voxbi One
• Minimum contract term, notice period, and termination terms on both lines
• Setup, onboarding, and porting fees
• The definition of "flat, unlimited" on Voxbi Managed and which destinations it covers
• The price or behaviour of AI usage beyond the 15-call monthly allowance
• The full list of countries where numbers can be bought and where porting is supported
• Whether TAPI CTI is gated by plan
• Whether Microsoft Teams is included or extra on Voxbi Managed tiers
• The methodology, sample size, and period behind the 4.64 satisfaction rating and the municipality and care-home percentages
• Whether an uptime status page exists
• Independent review platform presence
• Partner commission rates and partner certification requirements
• Whether the Eltrona coaxial backup path referenced on pbx.lu is still offered
