One-line summary: Visual Online (VO) is a 30-year-old Luxembourg internet, telephony, TV and hosting operator, 51% owned by POST Luxembourg, whose Cloud PBX is a resold Mitel MiVoice/MiCollab platform with public per-user pricing; it serves LU-centric SMEs that want one local vendor for connectivity plus phones, and is weakest for multi-country teams and buyers who want an independent, fast-moving cloud platform, which is where Mixvoip and pbx.lu are favourable.
Part 1 — Sales-ready intelligence
A. Sales battle card
Elevator pitch (theirs). VO is a long-established Luxembourg operator, backed by POST, that sells internet, Cloud PBX, SIP trunking, hotspots, hosting and TV from one local supplier. Its Cloud PBX is built on Mitel, with monthly per-user pricing and equipment billed separately.
Top 3 differentiators in our favour (Mixvoip / pbx.lu):
- Mixvoip runs its own cloud PBX platform (Voxbi), so feature velocity, AI Insights and integrations are not gated by a third-party vendor's roadmap.
- Mixvoip is regulated in 20+ countries (ILR, BNetzA, ARCEP, IBPT and more), so cross-border LU/BE/FR/DE teams sit on one regulated stack.
- Mixvoip holds ISO/IEC 27001 certification for its ISMS; no equivalent certification is published on VO's sites.
Top 3 differentiators in their favour (honest):
- POST Luxembourg owns 51% of VO, giving deep financial backing and access to POST's national FTTH footprint.
- VO operates its own Contern data centre and international backbone, so more of the stack is owned in-country.
- VO bundles TV (VOtv), hosting, colocation and domains alongside telephony, which suits buyers wanting a single broad local supplier.
Three pre-approved zingers:
- "Both of us host in Luxembourg and port your number. The real question is whose phone platform keeps shipping features every quarter."
- "VO resells Mitel. We build Voxbi ourselves. When you need a change, you call the people who write the code."
- "If your people work in Brussels, Trier and Metz too, ask who is the regulated operator in all of those countries."
Three things never to say:
- "VO is not a real operator." (False; VO is ILR-notified with its own carrier code and data centre.)
- "POST backing is a weakness." (It is a genuine strength; attacking it sounds defensive.)
- "Mitel is finished." (Mitel emerged from restructuring in June 2025 and keeps operating; overstating this is inaccurate and backfires.)
Walk-away signals (qualify out):
- Prospect is an existing POST/VO fibre customer mid-contract who only wants phones bolted onto that line and values single-invoice simplicity above all.
- Buyer specifically wants a Mitel desk-phone estate kept as-is, with no appetite to change platform.
- Pure-LU micro-business with no cross-border need, no integration need, and price as the only criterion at the entry tier.
B. Discovery question bank
Cost discovery
- Is your Cloud PBX quote per user per month, and are handsets inside that figure or billed separately?
- Did you get a written, itemised SIP trunk price, or was it quote-only after a call?
- What did installation and onboarding add on top of the monthly per-user price?
- Are call bundles (national, mobile, international) inside the licence or metered on top?
Feature discovery
- Which features sit only in the top tier, and which tier did you actually land on?
- How is your phone platform updated, and how often do new features arrive?
- Can your phone system talk to your CRM and to Microsoft Teams the way you need today?
- Where does call recording live, for how long, and who can pull analytics from it?
Operational discovery
- When something breaks, do you reach a Luxembourg team, and is the response time written into an SLA?
- If you open a site in Belgium, France or Germany, who is your regulated operator there?
- How are emergency calls and number portability handled if you move office?
- Who owns the platform your phones run on, and what is that vendor's roadmap?
Strategic discovery
- Is your telephony tied to your internet contract, and how easy is it to change one without the other?
- Does your provider hold a published information-security certification?
- Over the next three years, do you expect to consolidate more vendors or keep them separate?
C. Objection handling matrix
Objection | Why they say it | Underlying concern | Calibrated response | Proof point |
"VO is backed by POST, so it must be the safe choice." | POST is the national incumbent. | Stability and longevity. | POST backing is real and worth respecting. The phone platform itself is Mitel, not VO's own code. What happens when you need a feature changed: do you wait on a vendor in another country, or call the team that builds the platform? | Mitel filed Chapter 11 in March 2025 and emerged in June 2025; VO Cloud PBX page names the MiVoice/MiCollab platform. |
"We want one local supplier for everything." | Simplicity, single invoice. | Vendor sprawl. | Single-supplier simplicity makes sense. Mixvoip also delivers internet, mobile, SIP, IT and cloud PBX from Luxembourg on one invoice. Which services would you actually consolidate, and across how many countries? | Mixvoip offers internet, mobile, SIP, IT, cybersecurity and Voxbi cloud PBX across LU/BE/FR/DE. |
"VO already runs our fibre." | Incumbency. | Switching friction. | Keeping your fibre is fine; telephony can still move independently. If your phones and your line are locked together, how easily can you change one without renegotiating the other? | VO markets Cloud PBX and internet as a combined "all-in-one" proposition. |
"VO's Cloud PBX is cheaper at entry." | VO Basic starts at €5.00/user. | Budget. | The entry numbers are close; Voxbi Essential is €5.20. What matters is which tier carries the features you need and whether handsets are included. Which tier did your quote actually land on? | VO tiers €5/€7/€9/€11; Voxbi €5.20/€7.70/€11.20/€17.10, equipment separate in both. |
"Mitel is a trusted enterprise brand." | Mitel's long history. | Platform credibility. | Mitel is a serious brand. It is also pivoting to hybrid and handed its pure-cloud line toward a partner after restructuring. For a cloud-first deployment, does a hybrid-focused vendor roadmap match where you are heading? | Mitel discontinued MiCloud (now via RingCentral); MiVoice Connect is end-of-life. |
"We get number portability with VO." | Keeping the number. | Migration risk. | Portability is standard for any ILR operator, including us. So that is a tie. What else would make switching feel safe to you? | Both VO and Mixvoip are ILR-regulated and port LU numbers. |
"VO has its own data centre." | Contern facility. | Data location and resilience. | True, and your data stays in Luxembourg with us as well. Their Contern site is generally classed Tier 2; do your resilience requirements call for a higher-tier facility, and is that written anywhere? | VO Contern listed as carrier-neutral Tier 2 by data-centre registries; Voxbi hosted in LU cloud. |
"We only operate in Luxembourg, so cross-border does not matter." | Local-only footprint. | Relevance of multi-country. | Fair today. Many LU teams have staff commuting from or based across the border within a year or two. If that happened, would you want one regulated operator or a patchwork? | Mixvoip is regulated in 20+ countries incl. BE/FR/DE. |
"Their sales team will tailor a SIP trunk for us." | Bespoke feel. | Getting the right fit. | Tailoring is fine, but it usually means no public price. Would you rather start from a published rate card you can check, or from a number you cannot compare? | VO SIP trunk page is quote-only; Mixvoip publishes SIP and call-rate pages. |
"We trust a 30-year Luxembourg name." | Brand familiarity. | Trust. | Three decades is a real asset. Trust also comes from certifications you can verify. Does your provider publish an ISO 27001 certificate you can point your auditor to? | Mixvoip publishes ISO/IEC 27001; no VO equivalent found as of 23 June 2026. |
"Switching phone systems is too disruptive." | Change fatigue. | Downtime. | Most pain comes from poor migration planning, not the switch itself. If we mapped a cutover that kept your numbers and ran old and new in parallel, what would still worry you? | Number portability plus parallel running is standard practice for LU operators. |
D. Win/loss pattern map
We win when: the buyer has people or sites across LU/BE/FR/DE and wants one regulated operator across all of them; the buyer wants deep Microsoft Teams, Odoo or CRM integration and AI call insight; the buyer values a phone platform owned by the vendor with a visible roadmap; the buyer wants published SIP and feature pricing they can verify; the buyer needs an ISO 27001 supplier for procurement or audit.
We lose when: the prospect is already a POST or VO fibre customer who wants phones simply added to that line on one invoice; the prospect is committed to a Mitel desk-phone estate and culture; the buyer weights "national incumbent backing" and a single broad local supplier above platform agility; the deal is a pure-LU micro-business choosing only on the lowest entry tier; the buyer wants TV, colocation and domains from the same supplier as a hard requirement.
The deciding factor: whether the buyer values an owned, fast-moving, multi-country cloud platform (favours Mixvoip) or a POST-backed, broad, single-vendor local bundle (favours VO).
E. Pricing intelligence (estimated)
Public. VO publishes Cloud PBX pricing as four monthly per-user tiers, excluding VAT and excluding equipment: Basic Voice €5.00, Entry Voice €7.00, Standard Voice €9.00, Standard Plus Voice €11.00. Fibre Business is advertised from €43.00/month. SIP trunk pricing is not public and is quote-only via the sales team. Handset prices, installation, onboarding and call bundles are not published. VoIP call rates are exposed through a per-destination pricing tool on tools.vo.lu.
Item | Estimated range | Basis | Confidence |
Cloud PBX per user / month | €5.00 to €11.00 (published) | VO Cloud PBX page | High |
Mitel IP desk phone (one-off) | €90 to €350 per unit | Typical Mitel 6900-series street pricing; not on VO site | Low |
SIP trunk channel / month | €5 to €15 per channel | LU market norm; VO quote-only | Low |
Installation / onboarding (one-off) | €150 to €800+ | "Competitive installation costs" claim, unpriced | Low |
Fibre Business / month | from €43.00 (published) | VO internet page | High |
Number block / DID range | Not publicly confirmed | No public rate card | Low |
All non-published figures are analyst estimates only and must not be quoted to a prospect as VO's prices.

Part 3 — Deep research
1. Executive summary
Visual Online (VO) is one of Luxembourg's original internet providers, founded in 1996 and now 51% owned by POST Luxembourg through EPT, with the founding vehicle Trade-Comm holding 49%. It is a notified ILR operator with its own carrier code, its own backbone and a carrier-neutral data centre in Contern. Its business portfolio spans Fiber Business and Direct Internet Access (FiberConnect), Cloud PBX, SIP trunking, hardware, hotspot.lu, hosting, colocation, email, domains and the VOtv television service.
VO's Cloud PBX is a resold Mitel MiVoice platform with MiCollab collaboration, sold in four published per-user tiers from €5.00 to €11.00 per month, scaling to 250 users, with equipment billed separately. Public pricing on Cloud PBX is a transparency strength. SIP trunking, by contrast, is quote-only.
For a Luxembourg buyer, VO's appeal is a long-established, POST-backed local vendor that can supply connectivity, telephony, TV and hosting together, with everything kept in-country. Its constraints, viewed against Mixvoip, are a Cloud PBX tied to a third-party platform (Mitel, which restructured under Chapter 11 in 2025 and is pivoting toward hybrid), a single-country regulatory footprint, no publicly evidenced ISO 27001 certification, limited public feature and SLA detail, and weaker depth on modern integrations and AI call analytics. Mixvoip counters with its own Voxbi platform, multi-country regulation, published feature and SLA matrices, ISO 27001 and a faster cloud roadmap.
2. Company and market position
Visual Online S.A. was established as an S.à r.l. on 24 March 1996 and incorporated as an S.A. on 21 December 2000, with a share capital of €563,500. Its shareholders are EPT (POST Luxembourg) with 51% and Trade-Comm S.à r.l., the founders, with 49%. Claude Schuler is Managing Director; the board is chaired by Gaston Bohnenberger (EPT), with Claude Schuler as deputy chair and Gabriel de La Bourdonnaye (EPT) and Christian Gatti (TC) as directors.
VO positions itself as a hyperlocal Luxembourg operator: offices, technology and parent company all in-country. As a 51% POST subsidiary it draws on POST Technologies' national FTTH network, which independent coverage analysis ties to over 83% of Luxembourg households per ILR 2024 data. VO operates its own data centre in Contern, classed by data-centre registries as a carrier-neutral Tier 2 facility of roughly 3,300 square metres, with redundant power, UPS and generators, climate control and 24/7 secured access. VO is also a domain registrar via its dns-stock.com platform and runs the VOtv service, which is unusual in being open to any Luxembourg resident regardless of their internet provider.
In market terms VO is a credible second-tier Luxembourg operator: smaller and more telephony-light than its parent POST, but with genuine network and data-centre assets. Its telephony business overlaps directly with Mixvoip's core SME segment.

5. Service model assessment
VO presents a managed, advisor-led service model rather than self-service. Cloud PBX enquiries route to a named PBX expert and a contact form; SIP trunks route to the sales team; there is no online self-checkout for telephony. Onboarding is described in general terms ("rapid migration to the cloud", "competitive installation costs", "support included at no extra cost") without published timelines, SLAs or fees.
Local presence is a genuine strength: Luxembourg offices, Luxembourg data centre, Luxembourg-based staff, and a public website in English, French and German. Support is offered through a helpcenter and support portal, though response times and hours are not published. Migration support and number portability follow standard ILR-operator practice.
For SME friendliness, the published Cloud PBX tiers and a simple four-step ladder are approachable. For enterprise readiness, the picture is mixed: the platform scales to 250 users and offers ACD, CRM and operator console at the top tier, but there is little public detail on SLAs, multi-site architecture, redundancy of the PBX layer itself, or security certification. Hardware is Mitel-led and billed separately, which suits buyers who want managed desk phones and accept a capital outlay.
6. Pricing assessment
6.1 Public pricing summary
Cloud PBX is transparently priced at four monthly per-user tiers (€5/€7/€9/€11, excluding VAT, equipment separate). Fibre Business is advertised from €43/month. Per-destination call rates are exposed via an online tool. SIP trunking, handset prices, installation and onboarding are not public.
6.2 Transparency score: 3 / 5
VO earns credit for publishing Cloud PBX tiers and a live call-rate tool, which many LU competitors do not. It loses points because SIP trunk pricing is quote-only, equipment and installation are unpriced, and there is no public SLA or full feature matrix. By comparison, Mixvoip publishes a complete Voxbi feature-and-price matrix plus SLA tiers, which sets a higher transparency bar.
6.3 Likely hidden-cost risks
- Handsets and installation billed on top of the per-user price.
- SIP trunk cost only knowable after a sales conversation.
- Features such as ACD, CRM and operator console sit in the top tier, pushing some buyers up from the headline €5.
- Possible coupling of telephony pricing to a VO internet contract.
- Call bundles and international destinations metered separately from the licence.
6.4 Buyer questions to ask before signing
- Is the per-user price metered or flat, and what counts as a "user"?
- Are handsets, installation and onboarding quoted in writing and itemised?
- What exactly does each tier include, and which tier do I need for my features?
- What is the SIP trunk price per channel, and is there a minimum term?
- Is there a written SLA with response and repair times?
- Where is call recording stored, for how long, and at what cost beyond the default?
- Is telephony pricing conditional on taking VO internet?
- What are the one-off and recurring costs over a full 36-month term?
- Which integrations (Teams, CRM) are included versus chargeable?
- What are the exit and porting terms at end of contract?
- Is the Mitel platform roadmap and EOL position documented for my product?
- Do you hold an ISO 27001 or equivalent certificate I can give my auditor?
7. Ideal customer profile
Best fit
- Luxembourg SMEs that want one local, POST-backed supplier for internet, phones, TV and hosting.
- Existing VO or POST fibre customers adding telephony on the same line and invoice.
- Buyers comfortable with a Mitel desk-phone estate and managed, advisor-led onboarding.
- Organisations that value in-country data residency and a known 30-year local brand.
Poor fit
- Teams with staff or sites across Belgium, France or Germany needing one regulated operator.
- Buyers wanting deep Teams, Odoo or CRM integration and AI call analytics.
- Procurement that requires a published ISO 27001 certificate.
- Price-sensitive buyers who want fully public SIP and feature pricing to compare.
Watch-outs
- Platform dependence on Mitel and its hybrid pivot.
- Quote-only SIP pricing and unpriced equipment.
- Limited public detail on SLAs, security and PBX-layer resilience.
- Telephony potentially bundled with connectivity.
8. Strengths and weaknesses versus Mixvoip
Clear strengths (VO)
- POST Luxembourg majority ownership, with the financial and infrastructure depth that brings.
- Own Contern data centre and international backbone; more of the stack owned in-country.
- Access to POST's national FTTH footprint for connectivity.
- Broad single-vendor bundle including TV, hosting, colocation and domains.
- Public Cloud PBX pricing and a live call-rate tool.
- Long, stable 30-year local track record and trilingual local support.
Clear weaknesses (VO, vs Mixvoip)
- Cloud PBX is a resold Mitel platform, not VO-owned, so feature velocity depends on a third party that restructured under Chapter 11 in 2025 and is pivoting to hybrid.
- Single-country regulatory footprint; no own operator status in BE/FR/DE, where Mixvoip is regulated.
- No publicly evidenced ISO 27001 certification; Mixvoip holds one.
- Quote-only SIP pricing and no public SLA or full feature matrix; Mixvoip publishes both.
- Thinner modern integration story (Teams, Odoo, TAPI, AI Insights) than Voxbi.
- Equipment billed separately with no public handset pricing.
Neutral / depends-on-context
- Entry Cloud PBX pricing is close (VO €5.00 vs Voxbi €5.20).
- Both host in Luxembourg, are ILR-regulated and port numbers.
- Both use Gigaset DECT; VO standardises on Mitel desk phones, Voxbi on Yealink and Gigaset.
- VO owns a Tier 2 data centre, while Mixvoip layers over partner backbones and LU cloud; neither runs a Tier III/IV facility of its own, so infrastructure ownership is a genuine VO talking point but not a top-tier-DC claim.

ILR 2025 market data (official, end-2025)
The ILR Rapport statistique 2025 (data to 31/12/2025) partially closes the market-share evidence gap noted in section 13. Visual Online appears in exactly one ILR segment breakdown, the business-internet market, which fits its B2B-connectivity profile:
- Business internet: 3.0% of subscriptions, and declining (4.5% in 2021, 3.8% at end-2024, 3.0% at end-2025). Among non-incumbent providers it sits behind Mixvoip (7.8%), Orange (4.2%) and Proximus / Tango (3.6%), ahead of Cegecom (1.7%) and Luxembourg Online (1.3%); Post Luxembourg leads the segment at 78.3%.
- Not separately listed in the ILR residential-internet, mobile, fixed-telephony or TV operator tables. Its consumer-side and voice volumes fall within "autres" or roll up into its 51% parent, POST.
Accuracy note: this figure is from the ILR semestrial Excel series, whose labelled multi-period data show Visual Online steady-to-declining at roughly 3 to 4.5% since 2021. The published PDF pie (Graphique 40) appears to transpose Visual Online with Mixvoip, showing VO at 7.8%; the Excel series is the correct reading and the recommended citation. This resolves part of evidence gap 13 (VO's LU market share), though a telephony-specific share is still not broken out by ILR.

Bottom line
A Luxembourg business should seriously consider Visual Online when it wants a POST-backed, long-established local supplier to provide connectivity, telephony, TV and hosting together and is comfortable with a Mitel-based phone platform kept inside the country; it should look at Mixvoip instead when it needs an independently owned, fast-moving cloud PBX, multi-country regulated coverage across LU/BE/FR/DE, published feature, SLA and SIP pricing, and an ISO 27001-certified provider.
