One-line summary. Cegecom is the original alternative Luxembourg B2B telecom operator (1999), now part of the VSE-owned artelis group. Best fit for mid-market and enterprise buyers already inside the artelis fibre or datacentre footprint. Weakest for SMEs that want transparent pricing, a modern softphone, and ISP independence. Pbx.lu wins on per-user clarity, multi-platform Voxbi softphone, documented integrations, and ISP-agnostic voice.
Part 1 — Sales-ready intelligence
A. Sales battle card
Elevator pitch. Cegecom is a strong fibre and datacentre operator, but its cloud PBX is a quote-only, project-led product built on a third-party UC platform. Buyers who want clear per-user pricing, a modern multi-platform softphone, and independence from a single fibre vendor are better served by a modern cloud PBX.
Top 3 differentiators in our favour.
- Public per-user pricing and clear contract terms.
- Native multi-platform Voxbi softphone (web, Windows, macOS, iOS, Android) with click-to-dial and FMC.
- Documented CRM and automation integrations (Odoo, Office 365, Zapier, Make.com, public API).
Top 3 differentiators in their favour.
- Owned fibre network of over 1,500 km, with a low-latency Luxembourg–Frankfurt route.
- First Luxembourg Operator Connect partner for Microsoft Teams (AudioCodes SBC).
- Tier III and Tier IV data centres in Luxembourg, ISO 9001/14001/27001/45001 certified.
Three pre-approved zingers.
- "Ask them to send a per-user price by email. See how long that takes."
- "Their smartphone app is built by a German UC vendor (TeamFON), not by them."
- "Their managedLAN remote management runs Monday to Friday, 8 to 5. The world has moved on."
Three things never to say.
- Never say "they don't have fibre". They do, and they built much of it.
- Never say "they don't host in Luxembourg". They do, and they have ISO 27001 to prove it.
- Never say "they don't do Teams". They were the first Luxembourg Operator Connect partner.
Walk-away signals.
- Buyer demands a single-vendor wrap covering fibre, datacentre, and voice.
- Buyer has a named Cegecom project manager and a recent, successful migration.
- Buyer's primary driver is Luxembourg–Frankfurt low-latency connectivity.
B. Discovery question bank
Cost discovery.
- What is your all-in monthly cost per active user, including handsets and DECT licences?
- When is your next contract renewal date with Cegecom?
- Have you seen separate line items for managedLAN, dedicated lines, or feature package upgrades on your invoice?
- Do you know the exact wording of your termination clause?
Feature discovery.
- Which softphone do your users actually use on their laptops day-to-day?
- Can you show me where in the admin portal you configure call recording retention?
- Which CRM is connected to your phone system today, and how was that integration set up?
- How do you handle hybrid workers in France or Belgium who use a Luxembourg number?
Operational discovery.
- When you raise a ticket, what is the typical response time, and is there a public status page?
- Does Cegecom publish a roadmap for Managed Com that you can refer to?
- When did you last receive a feature upgrade, and what was it?
- Have you ever needed weekend support, and how did that go?
Strategic discovery.
- Are you considering moving fully to Microsoft Teams Phone for voice?
- Is there a CRM migration planned in the next 12 months?
- Who in your organisation decides to renew or switch telecoms?
C. Objection handling matrix
Objection | Why they say it | Underlying concern | Calibrated response | Proof point |
"Cegecom is a Luxembourg fibre operator, we trust them." | Brand familiarity, regulator-grade reputation | Data sovereignty, regulatory comfort | Acknowledge the trust. Point out we also host in Luxembourg with ISO 27001. The difference is in the cloud PBX product, not the infrastructure. Ask if they want to see the certificate. | Mixvoip ISO 27001 page, Luxembourg datacentre location |
"They are the only Operator Connect partner in Luxembourg, we need Teams Phone." | Familiarity with the marketing | Teams compatibility | Teams Phone has three paths: Operator Connect, Direct Routing, BYOC. Direct Routing works for most LU SMEs today. Offer a 15-minute review of which path fits best. | Mixvoip Teams Direct Routing page |
"Cegecom did a full audit and project-managed our last migration. We can't lose that." | Risk aversion | Migration risk, internal capacity | Project-led migrations are standard for any switch. We can show the playbook before any commitment. Offer three customer references. | Migration playbook, customer references |
"Their support is local." | Local relationship value | Response time and quality | Our support is also in Luxembourg, rated 4.64/5. Ask what their last response time was. | Mixvoip support ratings |
"Cegecom is cheaper than you." | Negotiation tactic, sometimes true | Cost pressure | Ask if that price is on paper. Some customers find the headline is lower but the all-in cost is not. Offer a line-by-line comparison of last 3 invoices. | TCO comparison sheet |
"They include Teams licensing." | Bundle convenience | Licensing simplicity | Teams licensing is usually a separate Microsoft purchase. Ask the buyer to check what their Microsoft 365 invoice currently includes. | Microsoft 365 licensing reference |
"We use their leased line, so we have to take their voice." | Bundle perception | Operational simplicity | That is a common perception. Operationally, voice can run over any business-grade internet. Offer to show how customers split the two. | ISP-independent customer story |
"Switching is too risky for our staff." | Change management | Operational disruption | Most migrations run a 2–4 week parallel period where both systems work side by side. Ask what they want to see at week one. | Parallel-run schedule |
"Cegecom is part of a big group, you're smaller." | Vendor stability | Risk of vendor failure | Mixvoip is the #2 fixed-line operator in Luxembourg and handles over 10% of all national traffic. Ask if there is a specific stability concern. | Mixvoip market position article |
"They have Tier IV data centres." | Trust in infrastructure | Reliability | True, and we host with the same class of partners. For cloud PBX, reliability is mostly in the application layer, not the data centre. Ask what uptime SLA they were offered. | SLA comparison |
D. Win/loss pattern map
We win when: the buyer is an SME under 100 users, values transparent per-user pricing, wants a modern multi-platform softphone, has a CRM project under way (Odoo, HubSpot, Salesforce), or wants to keep an existing internet provider.
We lose when: the buyer is a large mid-market or enterprise account already inside the artelis fibre or datacentre footprint, has a strong named-project-manager relationship at Cegecom, or requires a single-vendor wrap covering fibre, datacentre, and voice.
The deciding factor: whether the buyer wants a modern self-serve cloud PBX or a fully managed legacy-replacement project.
E. Pricing intelligence (estimated)
Public. No public price list for any Cegecom voice product as of 11 May 2026. Managed Com Business, Managed Com Corporate, Operator Connect, Direct Routing, and SIP-TRUNK are all quote-only. The only public Cegecom tariffs are the regulated RIO interconnection prices for other operators.
Our estimates. Confidence is low unless stated otherwise. These ranges are starting points for negotiation, not facts.
Item | Estimated range | Basis | Confidence |
Managed Com Business, per user/month | €25–45 | LU market range, RFP benchmarks | Low |
Managed Com Corporate, per user/month | €35–80+ | RFP benchmarks, dedicated-line dependency | Low |
Operator Connect, per user/month (excl. Teams licence) | €15–25 | Market benchmarks | Low |
Setup fee, mid-market project | €2,000–€8,000+ | Phase 1 audit + cutover scope | Low |
Handset (Yealink T54W class) | €180–€280 | Standard handset pricing | Medium |
ManagedLAN add-on, per site/month | €100–€500+ | Managed network add-on benchmark | Low |
SIP trunk per channel/month | €5–€15 | LU market range | Medium |
Contract length, typical | 24–36 months | Project-led migrations | Low |

Part 3 — Deep research
1. Executive summary
Cegecom S.A. is a Luxembourg-based alternative B2B telecom operator founded in 1999 as a spin-off from Cegedel (now Encevo/Enovos). It is a wholly owned subsidiary of the artelis group, majority-owned by VSE (Saarland, Germany). Cegecom runs more than 1,500 km of owned fibre, Tier III and Tier IV data centres in Luxembourg and Germany, and holds ISO 9001, 14001, 27001 and 45001 certifications. It targets enterprises, public institutions, and wholesale carriers. It does not serve consumers.
For voice, the commercial focus is Managed Com (cloud PBX, in Business and Corporate variants), Microsoft Teams via Operator Connect (positioned as Luxembourg's first Operator Connect partner, technically via AudioCodes) and Direct Routing, plus SIP trunks (8/30/60 channels) and legacy analogue/ISDN lines bundled inside the COMPLETE Internet packages. The smartphone app is built on the TeamFON platform.
Strengths: owned fibre, Luxembourg-hosted core, robust enterprise positioning, four ISO certifications, strong wholesale and datacentre bench, Operator Connect lead. Weaknesses: zero public pricing, dated public product pages, no public desktop softphone story, contact-form-only funnel, B1-level SME marketing, dependence on a third-party UC stack (TeamFON), and bundle bias.
Versus Mixvoip, Cegecom is enterprise-led and project-led; Mixvoip is SME-friendly, self-serve, and transparent. Cegecom is the right call for buyers who already buy artelis connectivity or datacentre services and want a single managed contract. Mixvoip is the better call for any SME that wants a modern softphone, clear pricing, and an ISP-agnostic stack.
2. Company and market position
Cegecom S.A. (RCSL B65734, VAT LU19245840, 3 rue Jean Piret, L-1027 Luxembourg, +352 26 499-1) was founded in August 1998 and launched commercially in 1999 as the country's first alternative fixed-line operator, created to use Cegedel's electricity corridors for fibre deployment.
In 2006, Cegecom and German operator VSE NET formed artelis. In 2017, Encevo sold its remaining stake to VSE AG, leaving artelis majority-owned by VSE (Saarland), with SaarLB as a minority financial holder. VSE sits within the wider E.ON energy group, which current management has publicly referenced as the parent ecosystem. The artelis group employs around 240 people in total, roughly 70 of them in Luxembourg.
Leadership: Serge Eiffes became CEO of cegecom, artelis and VSE Net on 1 January 2025, succeeding Didier Wasilewski. Eiffes has publicly framed the next chapter as a move from "alternative telecom operator" to "trusted ICT service provider", with new partnerships at Nexus 2025: Luxcontrol for cybersecurity audit and Dotika for AI strategy.
Market role: Cegecom is a Luxembourg B2B telecom and wholesale operator, not a consumer brand. The centre of gravity is connectivity (high-speed fibre, dark fibre, low-latency Lux–Frankfurt), data centre housing, security, and large enterprise voice. Cloud telephony is one part of a wider portfolio, not the core product.
3. Product portfolio for business telephony

5. Service model assessment
Onboarding. Project-based, three phases: site audit (numbering plan, call flows, network, mobile fleet), parallel-run installation, controlled cutover by the Cegecom NOC. A Cegecom project manager is assigned. Cegecom "reserves the right to revise this offer" after the audit, so the initial quote is not binding.
Migration. "100% managed and operated by cegecom". Number portability under ILR. Existing devices can sometimes be kept; the catalogue is the path of least resistance.
Support. A NOC with stated 24/7 response. Some service components (managedLAN remote management) are bounded to Mon–Fri 08:00–17:00. Contact-form and phone-line driven. No public chat, forum, or status page.
Languages. Website in FR/EN/DE. Support multilingualism plausible given LU/DE footprint but not advertised in detail.
Local presence. Single Luxembourg site at 3 rue Jean Piret. Group operations split Luxembourg and Saarbrücken. "Made in Luxembourg" badge.
Managed vs self-service. Strongly managed. Cegecom decides the architecture, ships the network terminal, defines the demarcation point, runs the platform. Customers manage extensions and forwards via UC myPortal or app. No self-onboard.
Hardware and provisioning. Cegecom supplies and provisions phones and DECT. DECT, FMC, DeskShare, and virtual subscribers each need at least Feature Package S.
Portability. Standard ILR. No accelerated timelines published.
SLA. Internet has tiers (ESSENTIAL, COMFORT, ELITE). Voice SLA referenced contractually, not published.
Enterprise readiness. Strong. Tier III/IV, four ISO certifications, geo-redundant, dedicated project management, low-latency Lux–Frankfurt route.
SME friendliness. Moderate to low. No public pricing, no self-serve, no online ordering, no tier for under-10 users. SMEs are filtered through a contact form into a sales process scaled for mid-sized projects.
6. Pricing assessment
6.1 Public pricing summary
No public price list for any Cegecom telephony product as of 11 May 2026. Managed Com Business and Corporate, COMPLETE, SIP-TRUNK, Operator Connect, and Direct Routing are all quote-only. The leaflets do not include per-user prices, setup fees, or hardware list prices. The RIO document is a regulated wholesale interconnection tariff, not a business buyer pricelist.
6.2 Transparency score
1 / 5. No per-user price, no published bundle, no published handset rate, no setup fee, no SLA upgrade fee, no contract length, no minimum term, no indexation clause. Even feature-package pricing (S/M/L) is referenced as a private "committed pricing table".
6.3 Likely hidden-cost risks
- Per-user feature package upgrades (S → M → L), with Package L gated by a paid workshop.
- ManagedLAN monthly fee if the customer LAN does not meet the published baseline.
- On-site service for customer-requested reconfigurations after handover.
- Delay charges for missed site access.
- Handset and DECT licensing per device.
- Dedicated-line / leased-line costs for Managed Com Corporate.
- Operator Connect minute-bundle overage outside the included zone.
- Likely 24–36-month contract length (inference, not confirmed).
- Termination conditions, not public.
6.4 Buyer questions to ask before signing
- What is the all-in monthly cost per active user across the smallest and largest feature pack, including handsets, DECT and FMC licences?
- What is the minimum contract term and the early termination fee?
- Is the per-site dedicated line included in the Managed Com Corporate per-extension fee or invoiced separately?
- Is managedLAN required for our network, and if so what is the monthly fee?
- What is the SLA for voice services, with response, restoration, and credit clauses?
- What is the Operator Connect bundle definition (included countries, minute caps, overage rate)?
- What is the call recording retention policy and where is it stored?
- Which CRM integrations are supported today, and which are on a dated roadmap?
- Is there a desktop softphone for Windows and macOS, or are users expected to use a desk phone, mobile app, or Teams?
- What happens to our service and our numbers if we move our internet to a different ISP?
- What is the migration cost to and from Cegecom, including porting, setup, training, and parallel-run?
- Does the proposal include usage-based fees, monthly minimums, or yearly indexation?
7. Ideal customer profile
Best fit
- Mid-market and enterprise customers already buying connectivity, fibre, or colocation from Cegecom / artelis.
- Financial-services and regulated firms in Luxembourg City wanting an ISO-27001 certified provider with Luxembourg-hosted voice.
- Multi-site Luxembourg or LU–DE corporates wanting free internal calls across customer sites.
- Companies standardising on Microsoft Teams Phone who want a Luxembourg-based Operator Connect carrier and a single SBC contract.
- Customers that value a managed-service relationship with a named project manager and a Luxembourg NOC.
Poor fit
- Micro-businesses (1–10 users) wanting fast, transparent, low-friction pricing.
- Companies that want full self-service and a 30-day rolling contract.
- Buyers who want a modern, multi-platform softphone as the primary endpoint.
- Buyers wanting a public roadmap, status page, release notes, and an active product community.
- Companies needing deep CRM integrations or strong API/automation tooling.
- ISP-agnostic buyers who do not want bundled internet, leased lines, or managed LAN as a precondition.
Watch-outs
- "100% migration managed by cegecom" is attractive, but the audit phase reserves the right to revise the offer.
- The Managed Com Business smartphone app is built on TeamFON (third-party UC vendor).
- Operator Connect lock-in: numbers must be ported out if you ever leave.
- 24/7 NOC ≠24/7 managedLAN support (Mon–Fri only).
8. Strengths and weaknesses versus Mixvoip
Clear strengths
- Owned 1,500+ km fibre network and own Luxembourg data centres (Tier III/IV).
- Strong wholesale and low-latency Luxembourg–Frankfurt route.
- ISO 9001, 14001, 27001, 45001, all current.
- Operator Connect for Microsoft Teams, Luxembourg first; AudioCodes SBC.
- 26 years of regulated operator history under ILR.
- Made-in-Luxembourg label and broad ICT positioning.
Clear weaknesses
- Zero public pricing across all telephony products.
- No publicly named desktop softphone for Windows or macOS comparable to Voxbi desktop.
- Mobile app developed by a third-party (TeamFON).
- Dated English product pages.
- No visible CRM connectors, public API, or automation surface (Zapier / Make / n8n).
- No public roadmap, release notes, status page, or customer satisfaction score.
- Heavy reliance on a contact-form sales funnel.
- Voice is one item in a broad ICT portfolio rather than the core product.
Neutral / depends on context
- Managed-service-heavy approach: asset for buyers with no IT staff, friction for autonomous buyers.
- Bundle bias (COMPLETE, dedicated lines) is good for "everything from one vendor" buyers, creates lock-in for ISP-agnostic ones.
- TeamFON-based stack is mature but ties Cegecom's UC roadmap to a German vendor.
- Greater Region free internal calling is useful for LU/BE/DE/FR clients, rare for fully Luxembourg-only SMEs.
- 2025 pivot toward "ICT services provider" broadens the offer; dilutes attention on telephony.

Bottom line. A Luxembourg business should seriously consider Cegecom when it is mid-market or larger, already buys fibre or colocation from artelis, is standardising on Microsoft Teams Phone via Operator Connect, and is comfortable with a project-led, quote-only sales process anchored by a Made-in-Luxembourg ISMS story. A Luxembourg business should look at Mixvoip instead when it wants transparent per-user pricing, a modern multi-platform softphone, ISP-independent voice, documented CRM and automation integrations, and a vendor whose primary product is cloud telephony rather than one item in a much broader ICT catalogue.
