BI Mixvoip

One-line summary: Mixvoip is Luxembourg's #2 fixed-line operator and the vendor-neutral guide's house product, selling Voxbi 2.0, a Europe-built and LU-hosted cloud PBX with public per-user pricing, a multi-platform softphone, AI call features and an open API. It fits SMEs and mid-market buyers (roughly 5 to 250 users) across LU, BE, FR and DE that want feature depth, price transparency and ISP-independent voice. It is a weaker fit for buyers who require CSSF PFS status end-to-end, an owned national mobile network, owned Tier IV data centres, or consumer retail presence, where DEEP, Orange or Tango may score higher on their own terms.

Part 1 — Reference intelligence

A. Capability and positioning summary

• Public, itemised per-user pricing across four named tiers, rare in the Luxembourg market.

• Voxbi 2.0 multi-platform softphone: browser, Windows, macOS, iOS, Android, with a shared feature set and a single Cockpit web admin interface.

• Documented modern feature surface: Microsoft Teams integration, IVR, call queues with ring policies and after-call work, call recording, AI Call Insights and transcription, live dashboards and analytics, Odoo and Microsoft 365 integration, public API, webhooks, TAPI, SSO and Active Directory.

• Access-agnostic: Voxbi runs over any business-grade internet, so the customer can keep or change their ISP.

• Multi-country reach: SIP termination and numbering across LU, BE, FR and DE under one tenant.

• ISO/IEC 27001 ISMS covering its telephony services, with recording options aligned to MiFID II and PSF expectations.

• Patented 2G-network mobile integration for call stability independent of VoIP and data.

• Not a CSSF "Professionnel du Secteur Financier" (PFS) entity in its own right; PFS-grade managed services need a partner stack. DEEP holds PFS directly.

• Resells mobile rather than owning a mobile network. Orange and Tango own their MNO and 5G spectrum; DEEP owns the POST mobile network.

• Does not own Tier IV data centres of its own; uses Tier III and IV partner facilities. DEEP owns three Tier IV sites in Luxembourg; Cegecom owns Tier III and IV sites.

• No consumer retail footprint or mass-market brand recognition. Orange and Tango have shops and decades of consumer presence.

• Has not won the Ookla "Best Fixed Network" award that Orange holds for H1 2025 and H1 2026.

• Smaller in headcount and group scope than the incumbents (POST/DEEP around 4,500 group staff; Proximus Luxembourg 700 to 800; Mixvoip is a focused B2B operator).

B. Reference question bank (capability framing)

1. Voxbi publishes four per-user tiers (Essential, Professional, Business, Enterprise) with both metered and flat-rate options; what does the competitor publish, and at which scope does it become quote-only?

2. What is included in the per-user price versus charged as an add-on (recording retention, additional history, SIP carrier, analytics)?

3. What is the contract horizon, and how does it compare to the competitor's 24 or 36-month commitments?

1. Does the buyer need Microsoft Teams calling, IVR, queues, recording, analytics, CRM integration or an API? Voxbi documents each as a product capability.

2. Which endpoints do users actually use: desk phone, browser, desktop softphone, mobile? Voxbi covers all four.

3. Does the buyer need AI call summaries, transcription or sentiment tagging? Voxbi ships Call Insights.

1. Is admin self-service (Voxbi Cockpit) or operator-ticket-driven at the competitor?

2. What SLA is in writing, and is it tied to internet or to the PBX software layer?

3. How fast can a user be added or removed, and by whom?

1. If the buyer changes ISP, does the phone system move with them? Voxbi is access-agnostic.

2. Are there employees in BE, FR or DE who need local numbers under one PBX?

3. Is there a compliance driver (PSF, MiFID II) that sets recording, retention and certification requirements?

C. Cross-competitor diff matrix

D. Buyer fit map (neutral)

• Wants public per-user pricing they can model without a sales call.

• Needs a modern multi-platform softphone as the primary endpoint, not just a desk phone or mobile twinning.

• Needs documented Teams calling, IVR, queues, recording, analytics, CRM integration or an API.

• Operates across LU, BE, FR or DE and wants local numbers under one PBX.

• Wants voice independent of the access provider, so the phone system survives an ISP change.

• Is an SME or mid-market firm of roughly 10 to 250 users that wants enterprise features without enterprise procurement complexity.

• Requires CSSF PFS status end-to-end on the voice path: DEEP (holds PFS directly).

• Wants a single state-owned full-stack incumbent with owned Tier IV data centres and the widest ISO and PCI scope: DEEP.

• Is already deep inside the artelis fibre, datacentre or wholesale footprint and wants one managed contract: Cegecom.

• Prioritises owned national fibre with award-winning consumer-grade quality and a single converged bill across mobile, fibre, TV and PBX: Orange.

• Is a 1 to 10-person Luxembourg-only office that wants the cheapest landline-replacement seat bundled with fibre and mobile on one invoice: Tango.

3. Product portfolio

4. Feature reference

5. Service model

6. Pricing assessment

6.1 Public pricing summary

6.2 Transparency posture

6.3 Cost considerations to be honest about

• Metered tiers bill per-user by usage; flat tiers cost more per seat but cap usage. The right tier depends on call volume, so "cheapest seat" is not automatically Voxbi or automatically a competitor.

• Recording retention, additional call history and external recording storage are add-ons above the base seat on most tiers.

• SIP carrier is included from Professional upward, not on Essential.

• Hardware, number ranges and internet (if taken from Mixvoip) are separate lines, as with any operator.

6.4 Buyer questions Mixvoip answers well

1. What is the exact per-user price for my tier and usage? (Public.)

2. Which features are in my tier versus add-ons? (Public matrix.)

3. Can I keep my ISP? (Yes.)

4. Can I get local numbers in BE, FR, DE? (Yes.)

5. Is there a desktop softphone and a browser client? (Yes, both.)

6. Is recording aligned to MiFID/PSF? (Yes, with caveats on PFS-grade managed services.)

7. Ideal customer profile

• SMEs and mid-market firms of roughly 10 to 250 users in LU and the Greater Region.

• Buyers who want public pricing and self-service administration.

• Teams-first organisations wanting proper queues, IVR and analytics, not just basic Teams calling.

• Multi-country teams needing local numbers in LU, BE, FR, DE under one PBX.

• Buyers who want voice independent of their internet provider.

• Regulated firms needing MiFID/PSF-aligned recording, where a partner handles any PFS-grade managed-service requirement.

• Buyers who require in-house CSSF PFS status on the voice path end-to-end.

• Buyers who want a single state-owned incumbent with owned Tier IV data centres and the widest ISO/PCI scope.

• 1 to 5-person Luxembourg-only offices whose only need is the cheapest landline seat on one bill.

• Buyers for whom owned national mobile network or consumer brand recognition is decisive.

• "Cheapest seat" comparisons can mislead: Voxbi metered vs flat tiers behave differently by call volume, and competitor headline prices often exclude add-ons.

• The PFS gap is real for the largest financial mandates; be explicit about the partner path rather than implying parity with DEEP.

8. Strengths and weaknesses versus the competitor set

Clear strengths

• Only product in the set with a full public per-user price book.

• Broadest documented feature surface (Teams, IVR, queues, recording, analytics, AI, CRM, API).

• Native multi-platform softphone (browser, Windows, macOS, iOS, Android) with one feature set.

• Multi-country numbering and SIP across LU, BE, FR, DE.

• Access-agnostic voice.

• Self-service Cockpit admin plus optional co-management.

• ISO 27001 ISMS with MiFID/PSF-aligned recording.

• Patented 2G mobile integration for call stability.

Clear weaknesses

• No in-house PFS status (DEEP has it).

• Resells mobile rather than owning an MNO (Orange, Tango, DEEP own theirs).

• No owned Tier IV data centres (DEEP and Cegecom own facilities).

• No consumer retail or mass-market brand (Orange, Tango have both).

• No Ookla "Best Fixed Network" award (Orange holds it).

• Smaller group scope than the incumbents.

Neutral / depends on context

• Voice-first focus is an asset for buyers optimising telephony, a limitation for buyers wanting one vendor for everything.

• Four-country footprint matters for cross-border buyers, less so for Luxembourg-only micro-businesses.

• Metered vs flat pricing flexibility helps some buyers, adds a modelling step for others.

• Partner-PFS model serves regulated buyers adequately but is not equivalent to DEEP's in-house PFS.
